Hi guys,
Just a quick warning -
Those Vicor VI-B62 modules are "booster" modules, intended to run with
a standard VI-J62 module (that's what the B in the part number means).
Booster modules don't have any of the control circuitry needed for
standalone operation, they won't work on their own.

Well folks I feel the jury is still out on the E-Volks Conversion.
I have one ... You get what you pay for ...
The key does not turn on the motor.
Okay, could you describe how yours works? Does yours have a
controller? If not, what does control the motor? Is the charger the
one shown on the website? Have you had any motor heating
issues? Does yours still have the exhaust system and gas tank? Is
the wiring properly done? Basically, does your's match this one? I
was struck by the contrasts in this one. It seemed as though the
rear battery rack, adapter and motor mount were well fabricated, and
some of the components well chosen, then the rest was a
hodge-podge. It was almost like the guy who had it together quit the company.

Where does someone go to fix a dc/dc converter? I have a DC Power converter
that has been acting up but I can't find anyone who will take a look at it.
(It doesn't help that I live on an Island in a sea of corn, Springfield
Illinois) I did buy a new one from Canadian EV but then the DC Power one
started working. BTW Randy took care of me on the return. Very high regards
to CEV or as a rapper would say a big shout out to CEV.
Thanks

Tim,
I agree with Lee in that the converter may be easy to fix.
Lee: Because the controller sends the 800 Hz PWM signal to the
converter, and the converter is always connected to the pack, is it
possible that the controller is doing all the regulation, and that the
converter is just a set of switching transistors? That might even make
it easier to fix.

Then why I'm drawing less amperes and can can double the speed at the same
voltage. Can run up a long hill at 60 mph at 300 amps for 2 minutes with no
problem, while the Warp 9 goes into over ampere!!!!
There was a test done between two engines with the same 225 HP rating in the
same vehicle. One engine was a 2 stroke and the other a 4 stroke. The 2
stroke accelerated twice as fast and had twice the speed as the 4 strokes. The
2 stroke had more torque than the 4 stroke even though the hp was the same.
I can explain the difference between the Warp 9 and GE 11.5 buy just looking at
the motor and battery amp and volt meters plus a E-meters and the feel of the
acceleration of the two different motors.
I can drive the EV in 4th gear with the GE which has a overall ratio of 5.57:1
at the same speed and ampere as the Warp 9 which is in the 2nd gear which has a
overall ratio of 13.925:1.
The GE is rated at 32 HP at 175 volts at 165 amps at 6000 RPM. I do not know
what the Warp 9 is rated at. There is no motor label on it. Some say it is 29
HP at 70 volts and the HP goes up with a voltage increase. Other say its is 65
hp at a higher voltage and I still cannot get what the maximum RPM of what it
should be.
The aluminum case Warp 9 motor runs a lot hotter and there is more brush arcing
then the GE. This is a brand new motor and there is a lot of brush noise which
is way more than the GE. The Warp 9 commentator is more rough than the GE
commentator. The GE commentator is Micro Mirror as well as the surface of the
silver brushes which are set at a steep 15 degree angle that bridges 4
commentator bars. The Warp 9 brushes only bridges two bars of the commentator
and the sharp edges are starting to chip away while the GE brushes are still
sharp after 20 years of usage!!

Hi All;
Have been holding my tongue on the State of the Onion address. Will
comment once, and be done with that.Seconding Michaela on that. All Bush had
to do was declare a National Emergency in the "Patriot Act" Theme.
Appropriate the Battery Tech Patents for the Panasonic type battery, sorry
Chevron and Texico, it's a National Emergency!Do a Manhattan Project type
thing. For you young non History Channel whippersnappers, the "Nuclr" bomb
was brought from a idea to a working example in about 5 years. Think of what
we could do for relatively simple battery teichnology, in less time.And a
hellova lot cheaper.like 2700 of our guyz ,an' counting, cheaper!
OK Back to the real nuts 'an bolts world. Got a Jetta flywheel, took it
down to my frendly machinist, chucked it up in the lathe and started pealing
off pounds of scrap iron. We cut it from 13 lbs down to SIX lbs!That should
make the car go easier. Got my Surraco Pressure plate and gunna assemble
things and hunt down a balancing place to get it balanced for 5-6 grand.No
more warn out bearings and a smoother than Diseasel EV now!?Put it together,
with my new, old 5 speed, instead of a 4speed, and a Rabbit with wall to
wall floors, no more flintstone mobile, seeing the road pass by underneith.
Lottsa stuff to do!

I have an ADC 9" with the regular fan inside. In reading the list for a
few years now, I wanted to
make sure I had plenty of cooling. And I'm always looking for ways to
improve efficiency. I'm up
in CT near Bob R. but in a hillier section. I can't go anywhere without
climbing a hill.
Hills really need the tranny in 1st . There are some here in florida , yes
we call them bridges and some are steep . I see the same amps going 60 as I
do going up one of these in 1st . keeping the motor rpm up is the key I
think .
I figured overcooling wouldn't hurt. And I could cool the electronics at
the same time.
If you have the time , Many times things trun out different than what you
think . I would have done alot of things different in my race truck , All
that time and money fooling with the clutch , for nothing , . Is your extra
cooling going to get in the way of maybe extra batteries ? Is there other
stuff you could be doing , like putting meters inside , batteries boxes ect.
Its easy to over do stuff , like the zilla cooling that was talked about ,
this is so simple but we did find may ways to "improve" on it here on the
list . I'm using the old gas lines .
Since I
haven't got the motor installed yet (still waiting for the adapter plate)
it's the perfect time to
do it.
Sounds like your looking for things to do , while waiting for the plate , .
Have you got all the bat boxes and stuff done . ?
I'm only an hour away from Limerock Park, one of my fantasies is to run
the car on that track.
There's a fairly active Porsche club in the area and I'd like to see if I
can impress anyone. More
fanatasy.
Unlike a lot of Fantasies this one will probable be more fun that you
though. Like showing up at a air show with a fly sauser , how fast or how
far won't matter much , and no airplane in the show will get the attion that
your UFO will .
y
Of course, it's all talk until I actually do it. Lot's of planning while
I'm waiting. Maybe too
much thinking about it. CAN'T WAIT to get started. But I can live
vicariously through the list
members.
I just started a conversion with a couple who live in the next town , this
will be number 16 for me and I am feeling that same way again . ,
Keep up with the lawn mower stories. I have a 6.7" motor destined for my
lawn tractor. I hope to
convert it in between the snow blowing and lawn mowing season.
I've had my mind blown twice in less that a year , ev lawn mower and the
race
truck , brains are all over the place :-)

Thanks for the input

Hey Rolan, all
News flash... Warfield uses OEM GE comm's on their Warp9 at least on the few
I've seen now. I've seen several posts on how GE comms can do 10K rpm's and
such, well I'd say they didn't or they got lucky, maybe an old steel comm
version, bottom line they are OEM GE comms on the Warp9's. As to a larger
motor, well more mass and turns equals less work and heat for the larger ones.
As to an aluminum case, I'm not sure what you mean as the housing is steel. As
to the brush to bar ratio, I've never seen a GE motor with larger brushes than
the GE style brush that Wafield uses on the Warp9. Warfield actually uses a
nice H100 grade and is a nice brush, although I don't much care for the metal
holders. The only reason that you are bridging 4 bars is do to a larger bar
count and the way the armature is wound. It sounds like the Warp9 is just to
small a motor for the load you have, in which a bigger motor is able to drive
the load easier and cooler and so gives you a better bru!
sh life
and less comm damage. Being I've yet to see a Warp 11 I have no input but I'm
sure the Comm's are OEM GE comms as well. Just thought I'd throw some info for
you guys to chew on.

I was shocked batteries were mentioned
But just a soundbite
Administration backs off Bush's vow to reduce Mideast oil imports
By Kevin G. Hall
Knight Ridder Newspapers February 2, 2006
WASHINGTON - One day after President Bush vowed to reduce America's
dependence on Middle East oil by cutting imports from there 75 percent by
2025, his energy secretary and national economic adviser said Wednesday that
the president didn't mean it literally.
What the president meant, they said in a conference call with reporters, was
that alternative fuels could displace an amount of oil imports equivalent to
most of what America is expected to import from the Middle East in 2025.
But America still would import oil from the Middle East, because that's
where the greatest oil supplies are.
The president's State of the Union reference to Mideast oil made headlines
nationwide Wednesday because of his assertion that "America is addicted to
oil" and his call to "break this addiction."
Bush vowed to fund research into better batteries for hybrid vehicles and
more production of the alternative fuel ethanol, setting a lofty goal of
replacing "more than 75 percent of our oil imports from the Middle East by
2025."
He pledged to "move beyond a petroleum-based economy and make our dependence
on Middle Eastern oil a thing of the past."
Not exactly, though, it turns out.
"This was purely an example," Energy Secretary Samuel Bodman said.
He said the broad goal was to displace foreign oil imports, from anywhere,
with domestic alternatives. He acknowledged that oil is a freely traded
commodity bought and sold globally by private firms. Consequently, it would
be very difficult to reduce imports from any single region, especially the
most oil-rich region on Earth.
Asked why the president used the words "the Middle East" when he didn't
really mean them, one administration official said Bush wanted to dramatize
the issue in a way that "every American sitting out there listening to the
speech understands." The official spoke only on condition of anonymity
because he feared that his remarks might get him in trouble.
Presidential adviser Dan Bartlett made a similar point in a briefing before
the speech. "I think one of the biggest concerns the American people have is
oil coming from the Middle East. It is a very volatile region," he said.
Through the first 11 months of 2005, the United States imported nearly 2.2
million barrels per day of oil from the Middle East nations of Saudi Arabia,
Kuwait and Iraq. That's less than 20 percent of the total U.S. daily imports
of 10.062 million barrels.
Imports account for about 60 percent of U.S. oil consumption.
Alan Hubbard, the director of the president's National Economic Council,
projects that America will import 6 million barrels of oil per day from the
Middle East in 2025 without major technological changes in energy
consumption.
The Bush administration believes that new technologies could reduce the
total daily U.S. oil demand by about 5.26 million barrels through
alternatives such as plug-in hybrids with rechargeable batteries,
hydrogen-powered cars and new ethanol products.
That means the new technologies could reduce America's oil appetite by the
equivalent of what we're expected to import from the Middle East by 2025,
Hubbard said.
But we'll still be importing plenty of oil, according to the Energy
Department's latest projection.
"In 2025, net petroleum imports, including both crude oil and refined
products, are expected to account for 60 percent of demand ... up from 58
percent in 2004," according to the Energy Information Administration's 2006
Annual Energy Outlook.
Some experts think Bush needs to do more to achieve his stated goal.
"We can achieve energy independence from the Middle East, but not with what
the president is proposing," said Craig Wolfe, the president of Americans
for Energy Independence in Studio City, Calif. "We need to slow the growth
in consumption. Our organization believes we need to do something about
conservation" and higher auto fuel-efficiency standards.

Hello to All,
Wow, 2006 is really shaping up to be quite busy for us at Plasma Boy
Racing! The year's excitement starts out in just two weeks, when Father
Time and I display our racing electrics at the prestigious Portland Rod
& Custom Show. Both White Zombie and Blue Meanie have been shown in the
original Portland Roadster Show in years past, and the hi pro EVs
created quite a buzz. A few years back, this spin-off show was started,
and today it's one of the biggest hot rod shows on the west coast.
J.N Foods, the folks Father Time built the blue Legend electric car for,
are hosting the booth and have invited us to bring White Zombie and
display it along-side the Legend car and one of FT's electric drag
motorcycles. You can catch a glimpse of the Legend car here:
<http://www.jnfoods.com/>
<http://www.suckamps.com/index.php?page=build_team_vehicles>
The details for this show can be found here:
<http://www.hotrodshows.com/prcs.html>\
This should be a real hoot, and it will be a great showcase for our hi
pro electrics. 10s of thousands will attend this show, so the EV
exposure will be huge. I can hardly wait to see the reaction of
hotrodders when they see '12.151 @ 106.25 mph' posted next to WZ and
watch it on video blow off muscle car after muscle car! We plan on
promoting NEDRA EVents, daily EVs as alternatives to the foreign oil
dependent gas car, and of course, the fun of building and driving a
muscular electric hotrod on the streets!
Maybe I should sent a personal email to President Bush and invite him to
see what patriotic Americans have been building in their backyards?
That'd make a pretty good photo-op, the president doing a burn-out in
White Zombie...or, dressed in leathers on Father Time's electric drag bike!

Hello to All,
This Sunday, Feb. 8th, we are having another one of our fun electric
breakfasts here in Portland at the Village Inn restaurant at 102nd &
S.E. Stark St. at 9:00 AM. All friends and EVers are invited to pull up
a chair, stuff their face, and enjoy the rowdy noise at our table.
Notable EVers that I know will be there so far, are Father Time, Rod
Wilde, Tim Brehm, Jim and Matt Husted, and yours truly. Rudman usually
can't resist the temptation, and Marko Mongillo might make it, too.
Hopefully, Victor can bring his ACRX and Ralph Merwin can show up in his
immaculate electric Prism. Tim and I will be driving White Zombie and
Blue Meanie, so local EVers, drive electric if you can.
See Ya.......John Wayland

Since it has an aircraft generator, the accellerator should have
controlled a rheostat, which sets the field current. This would have
provided very nice speed control and regen control. The fact that they
didn't suggests the builder is very unfamiliar with EV and motors.

No controller ... single contactor.
Originally the 36 Volt system. Purchased 2 extra batteries for 48
volts.
Key turns on Vehicle electrics ..
Throtle pedal connected to switch which energizes contactor which
turns on motor. Key must be turned on in order for throtle switch to
work.
Charger is a 12 - 72 volt 10/5 amp charger plus trickle charger for
aux bat.
Motor heating may be an issue depending on voltage .... What is too
hot ???
Gas tank and exhaust system intact ....
wiring and welding not up to my standards .. motor mount needs to
be stronger...
Vehicle is a shell needing work
Main problems ... No vacuum brakes !!! Motor noise (maybe thats how

Since it has an aircraft generator, the accellerator should have
controlled a rheostat, which sets the field current. This would have
provided very nice speed control and regen control. The fact that they
didn't suggests the builder is very unfamiliar with EV and motors.
Hm. Once you add field weakening, you really need to include a circuit
to watch armature current and bypass FW if armature gets too much power.
That might make for weird feelings when driving down the road.

I could take a look at it for you, and possibly fix it (depending on the
problem). After my DCP unit zorched -- multiple times, I've had it apart
and basically understand how everything is implemented inside. Though,
hopefully yours doesn't have the same problem(s) as mine and Mark
Farver's DCP units, or it's not going to be fun to fix (if at all). Did
I mention that I'm at school in Peoria, so I'm like an hour away.

OK, I'm kinda breaking my own rule about not talking about Bush, but
it's still relevant and tragically funny:
http://www.miami.com/mld/miamiherald/business/national/13768901.htm
"after President Bush vowed to reduce America's dependence on Middle
East oil by cutting imports from there 75 percent by 2025, his energy
secretary and national economic advisor said Wednesday that the
president didn't mean it literally."

My first EV had this setup; an aircraft generator, with the field
current set by a rheostat operated by the accellerator. It was actually
quite drivable. The accellerator response is odd; it acts like the
setting for a cruise control. At any given position, the vehicle tried
to hold a constant speed, whether up hill or down, motoring or regen as
needed. The current goes to whatever it takes to hold that speed; +500
to -500 amps.
The current could get excessive, but these generators have a (weak)
series field as well; connecting it in series softens the current peaks
and "cruise control" effect a bit.
This setup accellerates (and regens) so strongly that a beginner is
likely to break something. I burned up battery terminals, welded
contactors, etc. You really must include at least a fuse or circuit
breaker!

Considering Mr. Bushs' track record ie. No child left behind, which has
never been fully funded, in fact funds cut and that Bush is an Oil man; I
doubt his administration will support any real effort for this. Like most
Americans we wait for a crisis to fix a problem and the crisis has not
gotten bad enough to make a change.. People may gripe about gas prices but
they still buy big cars and truck and pay the price, it doesn't hurt that
much!!! Yet!
Just a thought. John

Subject: Bush mentions battery tech, EVs
I'll admit I've gotten out of the habit of listening to the US President's
State of the Union Address in the past few years, among other reasons
because the current president's delivery pattern just rubs me the wrong
way. Something about uncontrollable twitching when I hear "nukular" I
suppose.
But a few moments ago, Mark Farver informed me that yesterday's was one I
shouldn't have missed, and I'm surprised that it doesn't seem to have been
brought up on the list today. About 3/4 of the way through the speech,
Bush actually mentioned plans to "increase our research in better
batteries for hybrid and electric cars" among other energy initiatives
(nuclear, hydrogen, wind, solar, methanol, etc).
Maybe I'm overreacting, and I realize it's just one sentence in a speech,
but just that he included the terms "better batteries" and "electric cars"
in the same sentence during such an important address seems absolutely
huge to me. This wasn't an off-the-cuff comment; I think it's safe to
assume this was a speech worked over word-for-word, for days if not weeks.
Could this imply even a small shift in policy? Perhaps this might bring a
little less of the hydrogen extremism in government grant spending that
killed so much battery research in the past few years...
What do folks here think about this? Am I reading too much into this?
Positve and negative opinions welcome. (I guess if it's *really* negative,
maybe mail me privately...)

Yea I got it also from some Spam from Powerelectronics mag.
I looked into SiC free wheel diodes about a year ago. They could make some
gains in the power stage of my smaller chargers, but the forward voltage
drop was greater than some of the current
Infineon Die Silicon FRED diodes that I am currently using.
So the main power loss is forward conduction losses in our PFC chargers,
we would not have gained, and in fact we would have had more losses. On the
radiated emmissions created by the reverse recovery current spike, the SiC
diodes would basicly eliminate that effect.
I tried to get samples last year, and was not succesfull. I walked away
from the idea, until they get to be in stock and available in a TO-227
package.
Upping a 3 phase inverter from 12Kw to 110Kw is a RATHER large gain. I find
this amusing since the size and parts and everything else needed to move
110kw makes for a totally different machine.

The motor of choice will be a Netgain Impulse 9, which has the
same mounting bolt pattern as an ADC 8" motor.
Same bolt pattern, but longer shaft, so the adaptor needs to be
thicker. Although NetGain is working on this issue, as it currently
stands this motor is NOT a direct bolt-in replacement for the ADC 8",
so be aware of this difference in any adaptor design.

Hello Jim,
When I received this Warp 9, the first thing I look at was the difference of
brushes in the Warp and the GE. The Warp brushes are more soft graphite type
while the GE are more hard silver steel type. The GE commentator was Micro
Mirror, while the Warp commentator had a rough finish.
The brush holders in the GE hold the brush tight, while the brush holder in the
Warp lets the brushes rock a little. When I broke in the Warp brushes by
running it for 8 hours at 12 volts, the brushes make a clacking noise which can
be heard over 100 feet away. You cannot hear anything from the GE motor.
I received the GE motor in 1975 which was a proto type motor of only six had
its field and commentator windings wound a certain way, and they will not
release this info as of now. They were made for the Transformer I proto type
EV.
I order a spare brush set at the time, which I still not used yet. Back in
1976 these brush sets cost over $500.00!! That is half the cost of the Warp 9
motor!
Boy, I thought the housing was aluminum, so I went to look at it again and put
a magnet to it. The front 4.5 inches is aluminum and the back 2 inches is
aluminum and the center section is the steel part.

Hey Rolan, all
News flash... Warfield uses OEM GE comm's on their Warp9 at least on the
few I've seen now. I've seen several posts on how GE comms can do 10K rpm's
and such, well I'd say they didn't or they got lucky, maybe an old steel comm
version, bottom line they are OEM GE comms on the Warp9's. As to a larger
motor, well more mass and turns equals less work and heat for the larger ones.
As to an aluminum case, I'm not sure what you mean as the housing is steel. As
to the brush to bar ratio, I've never seen a GE motor with larger brushes than
the GE style brush that Wafield uses on the Warp9. Warfield actually uses a
nice H100 grade and is a nice brush, although I don't much care for the metal
holders. The only reason that you are bridging 4 bars is do to a larger bar
count and the way the armature is wound. It sounds like the Warp9 is just to
small a motor for the load you have, in which a bigger motor is able to drive
the load easier and cooler and so gives you a better b!
ru!
sh life
and less comm damage. Being I've yet to see a Warp 11 I have no input but
I'm sure the Comm's are OEM GE comms as well. Just thought I'd throw some info
for you guys to chew on.

Then why I'm drawing less amperes and can can double the speed at the same

There was a test done between two engines with the same 225 HP rating in the
same vehicle. One engine was a 2 stroke and the other a 4 stroke. The 2 stroke
accelerated twice as fast and had twice the speed as the 4 strokes. The 2
stroke had more torque than the 4 stroke even though the hp was the same.
I can explain the difference between the Warp 9 and GE 11.5 buy just looking
at the motor and battery amp and volt meters plus a E-meters and the feel of
the acceleration of the two different motors.
I can drive the EV in 4th gear with the GE which has a overall ratio of
5.57:1 at the same speed and ampere as the Warp 9 which is in the 2nd gear
which has a overall ratio of 13.925:1.
The GE is rated at 32 HP at 175 volts at 165 amps at 6000 RPM. I do not know
what the Warp 9 is rated at. There is no motor label on it. Some say it is 29
HP at 70 volts and the HP goes up with a voltage increase. Other say its is 65
hp at a higher voltage and I still cannot get what the maximum RPM of what it
should be.
The aluminum case Warp 9 motor runs a lot hotter and there is more brush
arcing then the GE. This is a brand new motor and there is a lot of brush noise
which is way more than the GE. The Warp 9 commentator is more rough than the GE
commentator. The GE commentator is Micro Mirror as well as the surface of the
silver brushes which are set at a steep 15 degree angle that bridges 4
commentator bars. The Warp 9 brushes only bridges two bars of the commentator
and the sharp edges are starting to chip away while the GE brushes are still
sharp after 20 years of usage!!

Perhaps you could explain what you mean here. If you have the same HP
and rpm then you have the same torque because torque times rpm divided
by 5252 equals horse power (HP * 5252 / rpm = torque in ft/lb.)
