Hello everybody
This is my first post and my first ev conversion.
Alot of questions but hopefully not too many.
I want to know if anyone can recommend 2 x
pancake or axial-gap motors to run the rear
wheels of my datsun b10. 1 motor 1 driveshaft x
2.
I would like something more powerful than the
Lynch LM200 or Etek. Also does anyone know if
Zebra will sell their z5 packs to the public or
group buy? from what Ive read in all the forums
Ive read, that it seems tp be the cheapest, most
reliable, durable and practical solution in the
long run. Apart from supplying them to the
military is there a reason why this 185kg pack is
not a common choice for those wanting less than
80klm range?
Kind regards, David.

Yeah, their eMini has very cool hub motors, but is it OK to not have
mechanical brakes (at least legality-wise in the EU)? How many of us
EVistas wish they had the $$$ for 4 corners of hubmotors and A123
pack...

Hi David,

I'd advise to stay away from those motors for a car or
truck. Even using two of them. I suggest you use a
wound field motor. And, if you do elect to do what
you suggest, you will need gear reduction between each
motor and wheel.

And as for Zebra? Don't know. Not too common around
here. I suspect they are expensive and only want to
deal with OEMs, not guys like you. Those are Sodium
Nickel Chloride or Sulphide, IIRC, and operate at very
high temp. Need thermal management systems and
special chargers, BMS, etc. Again, probably not a
good component choice for the beginner.

But hey, just my opinion. If you're up to it, go for
it.

Hope this helps,

Jeff M

Actually, I think the Zebra Sodium Nickel Chloride battery is a great
choice for the beginner since the thermal management and any required
BMS are already integrated into the battery package.

What everyone seems to overlook is that every chemistry needs some sort
of thermal management and/or BMS for best life and performance. NiMH
and NiZn don't like warm/hot temps and need cooling in most climates;
PbA don't like cold (reduced capacity) or hot (reduced life) temps, Li
don't like hot temps, etc.

The beauty of the Zebra in this regard is that it operates at a
temperature sufficiently above ambient anywhere on the planet that it
only needs heating no matter where your EV is operating, and the heating
system is built into the battery so you don't have to provide it.

The big downside is that last I heard they still weren't selling to
individuals, just OEMs.

Cheers,

Roger.

Yeah, a B210 is small, but probably not as small as other cars that
have used PM motors:

Don't know if a PMG-132 would be any better than an LEM-200, but it's
several hundred $'s cheaper.
