Ah, yes, the convenient click:
http://www.yahoo.com
Although they are touting fuel cells and things that much of this list
considers B.S., I am very pleased to see mainstream media promoting
EV's.
Nice work John, Bill, Rod, and others for getting attention in the race
community. Actually, I should say nice "play", as I am jealous and
wish I had the time and $$$$ to play too!
Racing is valuable for pushing certain performance characteristics of
technologies applicable to racing, as well as getting some positive
press, but it is important that this attention is backed up by vehicles
entering the market with the range, price, and other performance factors
that apply to everyday transportation demands.
I saw a Zenn car parked downtown yesterday. Cute, but not too many
people can pay $12,000 bucks for something having a 35 mi range and a
top speed of 25mph (realizing that some of these performance
limitations are to comply with classification statutes).
The start gun has been fired, the torque and speed hurdles have been
cleared, more hurdles and work to do before crossing the finish line.
OKay, OKay, I'll stop stating the obvious.

I know there are a FEW SEVA folks who read the EVDL, but may not
be on the SEVA E-Mail List... So here goes:
-----------------------------------------------------------
This is to announce that the April 10th SEVA Meeting will be
held at a NEW Location. ONE Block North, and One Block WEST of Chuck's
house At the Mosaic Community Coffee House. 44th St. and 2nd Ave.
It is in the Bacement of the Discovery House Church Building. South Side
of the Building. People who need to CHARAGE, could plug-In at Chucks,
and walk round the block to the Coffee House.
Check it out at: http://www.mosaiccoffeehouse.org/directions.html
Chuck, Dave B. and I have all checked it out, and it looks GOOD.
Lots of OFF Street Parking in the North Lot of Discovery House.
(Which is right in back of the Dicks Burger Place. Dave C....)
The COST is FREE for folks like US, but they do ask us to visit their
coffee house counter, and buy something (optional) The prices are also
OPTIONAL.. more like a reasonable DONATION.. That may be a little
confusing. I donated a few bucks for coffee and a beagle.
SEE YOU ALL THERE... For those NOT on the WEB or receiving E-mail from
SEVA, Chuck will have a sign, and directions up on his house.

there are many environmental issues with hydro-power that most folks are not
aware of. its effects on the carbon cycle being one of them. when a large
area becomes flooded the weathering of the rocks in the area changes and
depending on the composition much carbon can be released
But California and Canada

I was rather surprised by the amount of carbon generated, even by utilities
that get most of their power from hydro. EWEB (a local utility) published
their output, compared to PGE, another utility available locally. According
to their figures, they produce about 10% of the greenhouse gas output of
PGE, per kWh.

Hello
I'm looking for opinions and info about the Briggs & Stratton Etek DC
Electric Motor.
They claim:
-15 HP Peak, 8 HP continuous.
-Voltage........................12-50 VDC
-Max Nonload Current.....6 AMP.
-Max Nonload Speed........3600 RPM.
-MIN Nonload Speed.........3300 RPM.
-Min Speed at 160 Lbln.....3200 RPM.
-Max Current at 160 Lbln...150 AMPS.
-Shaft Size .......................1 3/4" x 7/8".
-Voltage Constant: 72 RPM per volt.
-Torque Constant: 1.14 in lbs/Amp.
-Continuous Current: 300 A 30 Sec.
-Weight: 20.8 lbs.
-Motor Diameter: 7.91"
-Motor Length: 5.64"
-Shaft Diameter: 7/8"-3/16" Keyway
- 50% smaller and 20% lighter (only 22.3 lbs.) than a competitive electric
motor - high power to weight ratio.
The number one choice of Evers everywhere.
At this stage of the game for me (learning stage) I'm clueless about the
significance of the numbers other than HP, Volts and current, but that
sounds a little fantastic for that size of motor.
So my question is this: Can a motor that small put out that kind of power?
Or is that pretty much inline with that is basically an 8" motor?
Thanks

Too bad this guy didn't see you FIRST! The Baldors make better boat

baldor in the Rabbit and fried it in a few weaks!Brushes are too small, comm
just doesn't have enough area. Maybe it'll run, but he';ll be looking for a
real motor soon enough!Is the Curset any good? If not, they will take eons
to get fixed?

Might be at a different temperature. Or it could be that the electrolyte is
a bit more concentrated in that battery. Is the manufacture date on that
battery the same as the rest of them?

I've been thinking for years that there should be a way to use the poly
strapping that often binds shipping crates. However, the gadgets I've found
to "buckle" it are some kind of untreated metal, which is apt to rust
ferociously.
I think I've seen the strapping secured in a way that looks like plastic
welding, but I don't know how one would do that at home. Anyone familiar
enough with the material I'm describing to have any ideas?
Also, am I wrong about the strapping's ability to stand up in service as a
battery restraint? Will it handle acid (or alkaline) spray and the like?

The issue here is that you'd have to hold the pressure below
10millitorrs (one atmosphere is ~750 torr ) to make a difference, if
it goes above that you'll be worse off.
That's some serious vacuum. It will be impossible to seal that
kind of vacuum in a motor that size unless you are actively
pumping during your run.
In my vacuum evaporation system (it goes to 1 micron... 1 micron
= 1 millitorr) there are no moving seals and I still have a hard
time keeping the vacuum there. When I close the vacuum pump off,
the chamber begins to climb to over 100 millitorr in a few seconds.
The off-gassing of the brushes (which are somewhat porous) would
take several hours to stabilize enough to maintain that kind of
vacuum, even with a fairly large vacuum pump. By the way, I use
my vacuum evaporation system to make studio condensor microphone
diaphragms. The vacuum pumping system is somewhat fragile and
bulky, too. I have a hard time moving it across the basement
without making it leak a bunch, let alone in a moving vehicle.
Each time I move it, I end up spending five or six hours
trying to find the leak.
To get things to seal against this vacuum level, every scratch
needs to be smoothed out. 2500 grit paper on a granite table
works well for this. Any electrical connection needs to be
run through a proper vacuum feedthrough. You can make these,
but it needs it. No bolts or screws or anything are allowed
between the inside of the motor and the outside. It becomes
very difficult.
Of course, at this point you might ask yourself, why not go AC and get
rid of the weak link.
I think this sounds right - the cost of a vacuum system to pump
down that low is about the same cost as one of the Azure AC
controllers - I bought the vacuum system and it was expensive.
I probably have put about $2500 into my evap system and the
vacuum pumps are still too small to deal even with tiny leaks.

The Etek is a good permanent magnet motor, but it is no 8"! ;^>
The 6.7", 7", 8", 9", etc. motors that people refer to are series-wound
DC motors, and are different animals from the permanent-magnet Etek.
Depending on what you plan to build, an Etek might be a good choice. It
is not suitable for on-road type vehicles other than motorcycles
perhaps.
Just for comparisons sake, an Advanced DC (brand) 8" series-wound motor
is rated 21.7HP continuous and 83HP peak (on 120VDC). At the same 150A
that the Etek develops 160in-lbs of torque, the ADC puts out 210in-lbs.
The ADC 8" is heavier than the Etek, which allows it to be run at higher
output for longer without overheating; the little Etek has little mass
and so will heat up more quickly and will overheat if asked to deliver
higher levels of power for extended periods (such as would be required
in an onroad/heavier vehicle climbing a grade, etc.).
Hope this helps,
Roger.

Hey all
Being my wife and mother-in-law work for the local
newspaper and what with all the fun stuff going on
(not to mention their nagging) 8^o I put together a
little write up about a local motor dork who's
building motors for a bunch of crazy, hairy ass
kissing (hey that's what I heard, LMAO), electric
record setting wacko's.
Being they were gonna do it with or without me I
figuered I'd better do it to get the tech stuff like
that correct 8^)
With Killacycles new record and being in last months
HotRod, not to mention Waylands record and Car and
Driver just coming out and with Shawns motor being
worked up the timing I figuered might be ripe for a
little rooster crowing. If it gets picked up I'll try
my best to not make a fool of myself and to make sure
to throw as much love to EVeryone both racers and
dailies as they will let me spout.
Keep you posted, wish me luck 8^) specially in the not
looking stupid part 8^P Watch the motor guys brain
flashover during a TV spot, LMAO, hehe. It's a small
town only other time she did this was for my haunted
house and I made the newspaper, radio, and TV crew at
the house! Let's see if they show up when it matters
8^)
Here's hoping!

How about flooding the comm area with inert gas under pressure during the
run.
Like a modified paintball gun with replaceable cartridges.
Would also provide motor cooling

I actually did a service call on them a number of
years ago. I can't remember why but I remember seeing
those big long motors 8^) I had one look at the
monsters and had to tell them I wasn't setup for
anything that big 8^( It was a fun trip though worthy

I rode in a ICE (Inter City Express) train in Germany last year. They
do very good energy management with speed and inertia. They go up
to 250kph and then almost all sound stops. Just wind and tracks.
It slowly looses speed until reaches 150kph where they brake
to 100 if they have to pass thru a station they are not stopping or
just brake to a stop if they will.
It was very well timed. They almost never had to re-apply power...

I'd look at the PMG-132 instead of the Etek. It looks to be a much stronger PM
motor, and can be used up to 72vdc. Motor Perm-Motor PMG-132 12-72 VDC

Vacuum limits you to 1 atmosphere.
Pressure has no (practical) limit.
The pressure vs. voltage breakdown curve for dry air is bath-tub shaped - U.
Pressure could reduce arcing, and even blow out an arc - as done at the
high voltage DC station here in Sylmar.
Leakage might even be a cooling advantage.
It might work for an EV.

I think inert gas would flash over also. Inert gas can become a plasma.
Gas under pressure would reduce flashover. Gas at partial vacume would be
worse. High vacuum would be O.K. but impossible to achieve. Just opinions
from my limited knowledge.

Nylon won't work for lead acid batteries, but would be O.K. for NiCd's which
have KOH electrolyte. Most tie wraps are nylon so won't work. It's possible
to custom mold glass reinforced poly urethane hold downs secured with
stainless bolts. Make molds with RTV. Or use 1/2 thick by severl inches
wide glastic strips to simultaneously hold down batteries in a pack.

I know that you can have nice low pressure lamps, so if you are able
to get a transparent part on the motor housing, then you can inspect
it as soon as you put some voltage on it - it will start glowing
internally all by itself.
You may be wasting some power there, not arcing but glowing away...
Cooling of the motor will also be zero, as normally these
motors are forced-air cooled (blower or internal fan)
Any bearing lubrication will disappear quickly and become a
different color in your 8" gas discharge lamp...
Other than that, it is a neat idea - besides the practicality
of a gas-tight seal under pressure at 5000 RPM.....

Subject: Re: Preventing Motor Flash Over (was RE: KillaCycle Update)
I was just thinking that if you could tighten the motor up enough that it
would hold the vacuum for 10 minutes or so, you could draw it down with a
big vacuum pump right before the race. No extra weight added to the vehicle.
It only has to hold the air out til you get to the end of the track. The
downside is extra heat build up inside without open inspection ports. Maybe
a forced air (or CO2) cooling shot after you get back to the pits.
Am I missing something here, would you not want to put NOS through an arcing
motor? Or are we considering the extra boost you'd see when the motor blows
of the rigging ;-)

Are you putting together a history display?
I hope you do not intend to put it in service,
next you will be asking for a vacuum tube motor controller?
If you want something historic and robust, the best choice
is an old SCR controller....
If you don't mind the howling and growling and reduced
efficiency of the peak-loading of your batteries (Peukert).
