HELLO

I'm trying to duplicate what Michael did here:

Using the G-29 Aircraft Generator, and no flywheel...a
direct connection to the transmission.

I have a 1204 upgraded controller from logi
48-72volts, and I ran 48volts to the armature through
the controller, and separate 24volts directly to the
field.

I used 8 awg wire for the 24 volt pack, and used a
RY115 relay, which I thought was 30 amp, but it blew,
so I removed a relay and connected through a 30 amp
fuse.

I then started the car, and I really did see that much
difference.

I guess all have to try a 72 volt pack, but I never
found those improved coil springs for the geo
metro...so I really didn't want to add another 200 lbs
in the rear.

Mike, I purchased from JCWhitney a set of helper
springs that bolt to the rear axle of a front wheel
drive vehicle. They have them rated from 1000lbs to
2000lbs. I purchased the 2000lbs version and so far
so good. I've got 13 golf cart batteries in the back
of the Eclipse.

If you aren't getting enough torque with the 24volt
field pack, you might try 36vdc. I seem to have
plenty of torque at 24vdc, but am running a 78vdc pack
for the armature.

Here's a link to the coil helper springs at JCWhitney:

Do these replace the rear springs I have?

Or is these an additional set?

They don't replace the original springs, just add them
to the axle just beind the others, as close to the
wheel you can. I believe a gentleman did post a
website earlier in the list of a company that sells
replacement coil springs to your weight specification.
I believe these addon springs I used are less
expensive though.

I'm working on a tight no money budget with my
project, so I've had to keep cost to a minimum. Still
hoping someday, I'll walk outside, and find that a 1K
zilla happened to be left on my doorstep to be adopted
by my EV....... LOL

DO NOT USED HELPER SPRINGS.
A friend of mind used them to fix bad springs which
where just worn out to get by on the Cheap. He was
driving down the freeway and hit a rough spot and the
helper springs Shot out side-ways and blew out both
rear tires. Car was not a pretty site after wards.

There has been a several discussion of this that you
need to order custom wound springs from a specialty
shop. I discovered going to a suspension shop for hot
rods that they will measure your car up for custom
springs and get them ordered up for you. a 4x4 custom

I bet that was an experience, that you'd not want to
do again for sure (was it an EV?). Thanks for that
heads up, I'll go back and install rubber bumpers on
the top portion of the car, where the springs sit, so
the springs are restricted from side to side movement.

I have a thought for you. instead of a separate battery pack for
the field, how about a DC\DC converter?
I found a Curtis 72/96 volts nominal, that puts out 10.7 amps at 28
volts. If the amperage is high enough it could save you a lot of
space and weight.

This machine has been garaged for 17 years.
I am upgrading it and getting it running. Tabitha,
my daughter, named it, "Pikachu". It's yellow and black,
electric and contains Japanese parts, so I went with it.

Yes, I've thought of that, but I think it needs more
amps, but not sure.

I'll have to measure the amps.

Could just use two 12v batteries, and put them on a
separate charger.

Well, it works

The problem is that these free old UPS batteries are
weak. I drove 6 miles.

I'm a little concerned about downshifting. It didn't
seem it wanted to do it.

What do you do when slowing down?

thanks

I haven't figured out anyway to really downshift with
the direct drive manual transmission either. I just
take it out of gear, and coast as much as possible,
and apply brakes gingerly. My EV isn't setup for any
REGEN, so I hope that taking it out of gear when
slowing down, and coasting to a stop is easier on the
controller, motor, and brakes.

Maybe a trip to the wrecking yard would suffice.
For example. I think the springs off of a jeep are the same diameter as
the rear springs on the 300zx, but stiffer and longer.

To downshift my clutchless EVs, I'd take my foot off the accelerator so
it's coasting, shift into neutral and then into the lower gear. The
transmission's synchronizers pulled the motor speed down to match. If
there was no need to hurry, a shift took a couple seconds. If I wanted
to do it more quickly, I pushed harder on the gearshift lever so the
synchronizers pulled the speeds together faster.

This works well with some transmissions, poorly with others.

Which car are you using with clutchless?

If it doesn't work, maybe I should live it in a lower
gear...

But I need to do more testing with a better battery
bank.

I have an '85 Geo Metro that shifts this way.

Hey Mike,

Michael had some problems with low starting torque. I
was able to give him help. I might be able to help

The shunt field should be a lot less than 30 amps.
Take the resistance and let me know.

Did or did not? What is your problem? Sorry if I
missed that in a previous post. What is it doing and
what is it not doing?

The higher pack voltage will help at higher speeds.
If you're working at lower speeds, like acceleration
from a stop, you should be in current limit and higher
pack voltage on the armature shouldn't play a role.

Give me some more details and I might offer some help.

A trick with early Rabbits when converting to EV was to double up the rear
struts, using two stock struts per side.

I measure 2.5 Ohms in the field, so using 24 volts is
pretty far from 30 amps. Not sure why it blew the
relay, maybe the initial surge kills it, and I need to
use a contactor?
