Leaf motor

Hi all

I am a bit confused. I taught Leaf motor was 4 pole PMSM. It states that here...
https://avt.inl.gov/sites/default/fi...nissanleaf.pdf

But i got other sources that say otherwise! Like this paper here it suggest that stator is 8 pole winding.

From your experience what is correct then?

It is 8 pole (4 pole pairs). Here's a video I just finished with testing it on our go-kart. I don't think it would spin if the pole pairs were wrong:

Whohoho! Very good! Only 50A phase 96Vdc and no shaking. I want to spin my motor now!!!

Seriously you should consider adding one switch to define direction. Put it on pin 10 maybe and we will cheer you try it .

Thanks for the great response i've been looking for crashed leaf or volt but they seem to be hard to find around here. I've been dooing some more research and found that the motor came out of a U.S. electricar back in the mid 90's.
I am looking for a dolphin controller or more documentation so I can interface it with Paul and Sabrina's controller.

Leaf Blog

I will try to show how i assemble and test my inverter here. Later i will probably try to log my second car conversion. Have fun reading.

Here's a quick demonstration of 50 amps of battery regen current, which was enough to make it skid to a halt:

Paul i am working on encoder mount now and will mount it the same way as resolver is mounted. Now since i have open collector A, B, Z signals i will have to pull them up to 5V with resistors. Can you suggest R value? I see you use 1K resistors to protect micro pins. Do i use 1K also, or could i use 4.7K. Or should i rather use 470R to make ports react faster? Or would you recommend changing input resistors from 1K to 470R?
RLS has 20mA draw limit for their encoder chip.

tnx

Arber
