I would appriciate some help around battery pack (A123, 20Ah pouch cells).
What configuration will be best:
112.2V, 60Ah, 6.732kWh
85.8V, 80Ah, 6,864kWh
Thanks

get a 144v 400A Kelly, then go 48s 2p (160v 40Ah A123 pouch) 6336kWh
Those motors dont mind higher voltage but high amps will kill the magnets.
But be sure to get the ME0913 (28 turn winding) and not the ME1012 (12 turn)

Thanks for the answer.

I have already bought 120V,300A controller so I am limited with this one. So the best way is to use higher voltage and reduce amps. And yes it is me913 motor.

Really?

Great

Always thought that not more than 96v voltage me0913

If you use 144v, so 144x57 = 8208rpm

Speed ​​too high

Rotor may crash? ?

it wont turn that fast on 165v, maybe 5500 free spin
on the road wont go past 4800

Strong thanks

I will buy me0913

Bought directly by

Magnet will not change, like you,

Therefore, high voltage will cause too much worry about the speed of

See Figure 80v voltage test can go to 4500rpm

==================================

I hope to drive high-voltage low-current motor

==================================

I used the google translator to communicate

Please understand

This is my idea

Another question...

I have removed fan cover and figured out that is only for turning in right direction, but for my aplication it has to turn left.

Is there any bidirectional fan or any other option?

Thats really a question for John at Motenergy
but yes I think he has made a new centrifugal diffuser fan for that motor.

Hi Ripperton,

Once again all the info and reports on your experiments are just great to see and hear about.

This is a question about cooling the PMAC-DS, ME0913 motor if it was installed in a VW bug. If a shroud were built to make a chamber around the cooling exhaust slots of the motor and then a good sized fan pulled a "vacuum" on that chamber do you feel it would work very well or be beneficial?

Thanks

Thanks

Thanks Zak
Nope, axial air flow doesnt work.
I already tried it, It just moves heat from one coil to the other.
And def dont use a 0913 in a bug, too small.
try this, they can supply a water cooled version
