I'm trying out Uve's and EVConvert's calculators. I've finally found my
gear ratios; they were posted online yesterday (two days too late!):
Honda AWD 5-speed transmission gear ratios:
SL: 4.512
1st: 3.384
2nd: 1.950
3rd: 1.275
4th: 0.941
5th: 0.783
Rev: 3.000
Reduction Ratio: 4.428
I assume I multiply the gear ratio by the reduction ratio and enter that
into the calculator. In this case, I get 19.979 for SuperLow! That's
*way* higher than any gear currently on the list.
With 175 70R13 tires, this results in a top speed of 23mph, limited by
motor rev. I was going 20mph on a 15-year-old used motor; that
corresponds to 6000 RPM.
Mystery solved. Tach sender and limiter ordered. About $300 of
investment to protect my next motor, just a few days too late.
I especially want to thank everyone on the list for your concern and
help. I've received numerous offers off-list for help repairing or
replacing the motor, including one who was willing to put off his own
motor install long enough to get me up and running again. I'm probably
going to rebuild this motor, or have it rebuilt.
This is the best mailing list I've ever been a part of. We may get
snippy over some issues, but we come together when a lister needs help.
Thanks again!

Every time I see hopeful claims by some company or university, instead of
getting excited I get a sick feeling, because there seems to be so much patent
squatting and such. I just read a post from Noel Adams on another list about
how MIT (much like the Chevron/Texaco/Cobasys thing) just sits on the research
or discovery and doesn't go forward with it, much to the dismay of the actual
discoverer/inventor as the rights belong to MIT not to the researcher.
Chet
P.S. I heard from someone else that whoever actually provides the funding for
the research is the owner of anything discovered. Is this true?

Hey there everyone,
RAN is movin' and shakin', so we're hiring a new campaigner for the Zero
Emissions /Jumpstart Ford Campaign. Join an amazing team of 4 at a
visionary and hard-hitting organization! Good pay and great benefits.
Apply and pass it around!
(And for those of you who are interested in the nitty gritty of our recent
restructuring, Jen Krill was promoted to Program Director and I've moved up

RAN Job Opening
Zero Emissions Campaigner
***********************************
Position: Zero Emissions Campaigner
Supervisor: Zero Emissions Campaign Director
Salary: DOE, plus benefits
Status: Full time, salary
Location: San Francisco
Close Date: August 14, 2006
Position Summary:
Rainforest Action Network (RAN) runs hard-hitting campaigns to protect the
world's forests and their traditional inhabitants from extractive industries
and the effects of climate change. Our campaigns focus on high-impact
market sectors including the logging, private financial and automotive
industries. RAN seeks to galvanize the public's existing belief that
irresponsible resource extraction in endangered ecosystems is unnecessary,
that climate change is a threat to global ecosystems and the global economy,
and that a mature, modern society must build towards a more just and
sustainable future. The Zero Emissions Campaign focuses on the auto
industry, and is campaigning to Jumpstart Ford, working to end our
dependence on oil and eliminate global warming pollution from vehicles. Ford
Motor Company has the worst fuel economy and the worst per-vehicle
greenhouse gas emissions.
The Zero Emissions Campaigner is responsible for executing grassroots and
online organizing strategies to build broad movement support for the
Jumpstart Ford campaign and RAN's work in general. The campaigner will work
as the third member of the Zero Emissions team and collaborate closely with
the larger campaigns and grassroots organizing teams.
Qualifications:
The Zero Emissions Campaigner position requires superior written and verbal
communication skills, coalition building skills, and networking skills.
Prioritizing tasks, volunteer coordination, and the ability to empower and
motivate grassroots activists in carrying out campaign tactics are
necessary. The position requires good decision-making skills, strategic
insight, professional initiative and results-oriented behavior. Previous
successful campaign or organizing experience is required; nonviolent direct
action experience is an asset.
Expertise and experience in working with indigenous and affected communities
and on issues of oil and climate justice is strongly preferred. Knowledge
of issues including grassroots organizing, corporate social responsibility,
climate change, biodiversity, human rights, fossil and renewable energy
politics, the auto industry, and common solutions to the internal combustion
engine is an asset. Must be able to travel frequently.
Specific duties include:
. Execute grassroots campaign strategies to pressure Ford Motor
Company to dramatically improve its fleetwide fuel efficiency and to
eliminate greenhouse gas emissions by 2020, and to build plug-in, or
gasoline optional (GO) hybrids.
. Strengthen RAN campaigns by working with campaign staff to mobilize
grassroots activists on key forest and climate change issues;
. Strengthen, broaden, and diversify RAN's network of climate change,
human rights, peace and justice, and forest activists and groups;
. Build capacity within the movement and support grassroots efforts
with organizing advice, resources, materials, and campaign strategy;
. Co-coordinate gatherings and trainings of RAN-affiliated activists;
. Direct, facilitate, and participate in other regional and national
organizing and campaign training sessions;
. Maintain relationships with close coalition partners and allies
through organizing, outreach and corporate negotiations;
. Develop a plan with the Zero Emissions Campaign team and other
interested parties at RAN to coordinate with organized labor on the Ford
campaign;
. Prepare materials for the Zero Emissions campaign and RAN as a
whole, including website, fact sheets, action alerts, etc;
. In conjunction with appropriate Campaign Director, Organizing
Director, and Communications Director, develop and implement regular
strategic communications with RAN members, funders and activists;
. Maintain Jumpstart Ford activist lists within RAN's online activist
community, and coordinate with other lists within RAN in order to grow RAN's
online activist presence;
. Coordinate annually (and as needed) with the Zero Emissions
campaign team to design the strategic plan and budget for the Zero Emissions
campaign;
. Represent RAN at environmental conferences and provide motivation
and tools to grassroots constituencies. Act as a public spokesperson for RAN
and the Zero Emissions campaign as needed;

diversity initiatives, and training sessions. Share office responsibilities
to maintain a healthy and safe work place;
. Report to Zero Emissions Campaign Director regularly on
accomplishments and plans of action;
. Participate in annual performance reviews with the Zero Emissions
Campaign Director as well as weekly campaign team meetings.
RAN values diversity, educates staff on issues including privilege and
oppression, and integrates these values into all of our work. We are seeking
candidates who have a commitment to engage in this process and work with us
to create a just, inclusive, and sustainable work environment and world. RAN
provides all people with equal employment and volunteer opportunities.

Doug please tell us more about this motor. I didn't realise there was
something like this. How is the efficiency and power compared to other DC
brushless and brushed systems? How would it work in the 72 to 120v range on
a motorcycle weighing a maximum of 850 pounds with a 250 pound rider?
Lawrence Rhodes...
This is a brushless DC motor, with permanent magnet rotor and the 3-phase
windings on the stator. The circuit board is the electronic commutator,
that does the function of brushes with MOSFET switches. (So it is quite
different construction than the E-tek brush type motors.) Because of the
electronic commutator, the CMG motors can be speed controlled using
conventional DC motor controllers, such as the Alltrax series, or operated
without a controller, with the built-in ramp-up/soft start, for constant
full speed applications.
The choice of model depends mainly on the RPM required, power/current level
and battery pack voltage. Contact me direct if interested - I am a
distributor for eCycle.
Best Regards,
Doug

Hi MIke. I was wondering why you need the upgrade? Are you having trouble
with speed? Is the motor you now have capable of bringing the boat up to
waterline length speed? It might be possible to save your current setup
with a few tweeks. Don't forget if you do upgrade to put your used
components on the EV Tradin Post. Lawrence Rhodes......

When I plug in a single phase motor to the outlet, it should spin on
its own right? So then the dc motor should try and spin the induction
motor a little quicker. So the faster it spins the more current I can
push into the grid? So what motor should be powered first? If the
inductions motor starts spinning then the dc motor becomes a generator.
I think a load of around 25 amps on a 6.5ah pack would only take 1/4 hour.

Yes; for generating single-phase AC, you use a single-phase induction
motor.

. Chelsea made her
grand entrance by driving the RAV into the courtyard were we had the other
cars on display. It was a great team effort to get everything to happen,
but
would have been just an EV sitting outside the theatre if not for Charles'
extreme passion for EVs. Thanks Charles!!!
Hi all , the wktec event for me was like the last few EV events I've been to
, a very hard push to get some EV done and there , working on the Ev right
up to the last min , but in the end feeling like it was all worth it . I had
talked with Paul about putting all the EV parts from my race truck into one
of His
Diablo's but wasn't thinking of the movie or any time frame.
Some how Charles gets us promision to park some Ev's in the court yard at
the theatre ( not an easy job ) and now both Charles and Paul are thinking
"EV Diablo
needs to be their" . Charles didn't stop with just getting the news papers ,
and the star of the film to come , he's on the phone to me , " Sure would
be nice if you and Paul could get that Diablo for the show ". Last year
before the BBB event (Florida's first ev drag race ) when the truck was
flying together for the event and I had the last min problems , Charles gave
me the "pep talk " and somehow I made it , I didn't think it was going to
happen this time , not in 2 weeks and no spare time . He must of said the
right things to Paul as he to was bugging me to try to get it done to and
was going to have his guys working on it also . . I drove my 40 golf cart
bat EV work truck the 70 miles to Paul's and we pulled the engine out of the
Diablo kit car and I headed back with the tranny in the back . This is
summer and I'm mowing my butt off trying to keep up with the lawn business .
I have to pull the motor out of the race truck for starters , make the
adapter plate and coupler and somehow find time to get it back to Paul .
part 2 , a new way to kill an e meter ,

Hi EVerybody;
Well, Gees! I didn't know how far ahead of things I was with my 65 Monza
conversion, back in the early 70's! I piled my usual 120 volts worth of
Exide 90 sumething green badd-eries aboard, A Yale forktruck motor and my
Rectacter controller, which lived on to go in my Rabbit much later. I
really liked that Corvair, It had Drum brakes all around, Had to put Buick
springs all around to get it off the blocks. Would do about 70 wide open.
Had a decent 50 mile range, was fire engine red, like YOUR'S , Lee! I see
that 'vair in yur driveway, and with a 9 inch motor and at least a Rapture,
or Zilla, you would have a cool retro EV! I blew out the motror a few times
and when I left Citicar in Sebring I sold it to a guy who liked Corvairs and
(Gasp) was gunna convert it to GAS!It may STILL be in Sebring Fla, sprewing
oil down the road?Corvairs made nice conversions, lottsa room to stuff
badd-eries, 9 went in front, 4 behind the back seat and the rest in the
engine room.I would imagine they are harder to find nowadaze than
Rabbbits!?I remember scrounging parts on long road trips, stupid shit, like
tail lite lenzes, bumperettes etc.Like TRYING to find a clean Nissan corner
marker lite nowadaze on my relatively new Sentra.As they wern't common , the
too door coup, at least.I think the old Ford Falcon's would make EV's. They
are light, kids had a few, pushing dead ones around was easy! But I don't
wanna spend EONS fixing it up as a car, before putting a EV motor in it!But
I think the retro thing would be fun. Kid bought a CA Falcon in oh so-so
condition, drives it in the summer, just for fun.Boy are they EASY to work
on !!All the gas stuff is right THERE when you open the hood!Bare Bones
Basic Gas tech!And they get decent miliage, too.But I like my Prius
better.My trusty old Ford van, ya might of met it at Joliet is like that.
Easy to fix, faithful, swallows up a big load of whatever, lumbers along as
a tow vehicle, in the 50's all day, on one tank of gas! Had I put the Rabbit
on a trailer, probasbly STILL would have it? Ford wouldn't have cared. A few
thousand lbs?
Sooooo IF ya can find a clean ' Vair, go for it. Convert it and do car
shows and cruise nights!
My two watts worth.

I would connect up the induction motor to the grid with a low wattage
incandescent light bulb, an ammeter, and the motor in series, light bulb
should be bright but the motor should not turn.
Now bring the DC motor up to speed and as you do the light bulb should get
dimmer until it goes out. Flip a switch that shorts out the light bulb and
then speed up the DC motor a bit more until you get the current you want.

Hey Ron;
You didn't say if a 45 mile commute was RT or OW?? This is a biggie here.
I ran a 82 Rabbit, maybe Golf in the UK? A lite shitbox car stuffed with 20
golf cart batteries, so I could get home for sure IF my plugs were Iced at
work.I ran on the turnpike at 60-70MPH like yur Motorways, most of the way.
I worked at the RR as a train driver, and wired a set of plug-in's at the
roundhouse area, nobody cared, whats a few amps in a train yard of electric
trains?I lived happily for YEARS with a 120 volt outlet and a 100 foot or
more 'stench chord!THAT was my dropping resister for a Bad Boy charging
setup! In UK build a 240 volt car and just plugitin with a simple full wave
bridge.There MUST be nice lite small cars in UK that would make good donar
cars?Or do all your older cars disolve in dismaying blights of rust in 10
years as they do in CT, USA?

Doug,
Thanks for your reply.
My research on the internet has not found much, other than marketing info,
about the ecycle motor.
Can you tell me about users' experiences with the motor either in a
manufactured product (outboard, etc) or in a "homegrown" project?
I'd like to know how long some of your customers have been using the motor.
Does its performance seem to match the marketing info? Is it really 95%
efficient (does motor stay cool)?
One of the few messages I found about the ecycle claimed that the earlier
versions had problems with loose components on the circuit board causing
"shorts". Has this been solved? Any other problems to be aware of? What is
your return rate?
Thanks.
Mike

Hi Jim;
Well, ya probably couldn't get the link? Dammit! was a great tunnel vid
camera catching great spinouts in a iceed tunnel in Russia, water had leaked
in and frozen. Can you think Black Ice? Cool bus shalums, with the
articulated veriety, no less, an Olympic TEN on that one. The two streight
trux piling up so elegently!I'll bet it was on "You Tube", too. Go to you
tube for great vid clipsYou can waste HOURS in there!Like RR stuff for
me.-I'll keep tryin! S

I've been looking at these little Toyota vans for a while. They seem to
me to be a reasonable candidate for conversion. I found one in a
parking lot one day so I got out my tape measure and poked around under
neath it. I think I could get 24 batteries under the floor if I can get
enough ground clearance for an 11" tall battery box. The vans came in a
4wd configuration that has a lot more ground clearance than the 2wd
version. The GVWR is about 5000 lbs, while the curb weight of the 2wd
version is about 3200lbs. This is starting to look promising. They use
a 3Y-EC or 4Y-EC engine and came with either a 3speed automatic or 5
speed standard transmission. They are rear wheel drive and have either
leaf springs in the rear or 4 link. The front is torsion bars.
I'm thinking that if I could find a 4wd, I'd swap out the transmission
for a 2wd standard type and take out all the fwd equipment. I'd also
get one with leaf springs so that I can add helper springs. I'd be
looking for a lift kit to get the loaded ground clearance from the floor
pan to be in the 20" range.
The 2wd version has about an 15" ground clearance unloaded. I haven't
found a 4wd version sitting still that I can measure yet. Does anyone
have access to one that they could get me this measurement?
Then comes the problem of attaching the battery boxes under the floor of
a unibody design. I'd need some serious mechanical consulting to get
this right so that the batteries are easy to drop.

The performance specs are extremely dubious! It is so very easy to just type
in your assumptions without any real proof.

Simply spin an induction motor above synchronous speed, and connect it
to the grid. It automatically becomes a generator.
The winding voltage and frequency have to match the AC line's voltage
and frequency. This is easy with a single phase motor, as the winding
voltage *is* the line voltage. For example, a single-phase motor rated
"115vac 60hz 3450 rpm" has a synchronous speed of 3600 rpm (slip is
3600-3450=150 rpm). So spin it at 3600+150=3750 rpm to *generate* 115vac
60hz.
With a 3-phase motor, just use one phase for generating single-phase AC.
The challenge will be finding a motor that has a 115vac winding! Most
3-phase motors are for higher voltages. Plus, the windings may be
Y-connected; this means three 120vac phase windings have one end tied
together internally, and the other ends are the 3 phase supply wires;
this makes a 208vac motor. You'd have to take it apart to get at the
other end of one of the phase windings.

Right again! The motor-generator pair works exactly like a transformer
(except that the DC side is drawing/generating DC current).
The AC induction motor wants to run very near synchronous speed. If your
DC motor is PM, it therefore has to run at that same speed. It therefore
wants to produce the same DC voltage. It generates current if you try to
slow it down, and absorbs power (pushes it back into the AC line) if you
try to spin it faster.
To use this setup as a general-purpose charger/load, a DC motor with a
wound field would be best. That lets you adjust the DC side's voltage,
and consequently control the current flow.

Approximately correct. The amphour capacity is reduced though at higher
currents.

Take a look at our BEST group's website www.bestoutreach.com for ideas.
BEST mentors 4th-6th graders to design and build their own vehicles from
scratch. They have to scrounge for materials and spend less than $100.
Their vehicles typically use a 12v 30amphour sealed battery, and one or
two automotive 12v motors (like those used for radiator fans, heater
blowers, etc.) They use a lot of bike parts, scrap lumber, plastic pipe,
broken furniture, etc. Their vehicles usually go 10-20 mph and have a
range of 10 miles or so on a charge.
Their designs are often EXTREMELY imaginative. We've had beds on wheels,
fan-driven cars, 2-wheel Segway clones, cardboard cars, cars made out of
wooden hobby horses, etc. The kids construction is usually ramshackle
"Little Rascal" quality, but they work!
An adult built version can be a lot sturdier and more reliable. Just
don't get carried away in "perfectionist" mode!

Last year, each BEST team used a Hawker SBS60/2 12v 54ah battery
(www.surpluscenter.com intem 11-3096, $34.95) and a Warner Electric
gearmotor, 12v 20amps 150rpm (www.surpluscenter item 5-1524, $39.95).
With an adult and a 100-pound vehicle, geared for about 10 mph, these
parts would give you about a 10 mile range. Use two motors and batteries
for more.

Yes, you could make this work. You need an inductor, as shown in your
schematic, because the controller is designed to only work into an
inductive load. The motor's series field is good enough. Connect your
battery pack in place of the series motor's armature.
