Erratic braking on vesc using large hub motor.

Hi all,

Im currently building a large electric scooter im using the VESC 100/250 when i use the regen braking its cuts out like its pulsing off and on really fast. In the app i was getting an over current error but the regen is set at 10 amps and it still does it im running out of ideas on how to resolve this issue.

Cheers

Try Setting Stator Saturation Compensation to 15%. Sounds like the Vesc is losing the Rotor Position while braking.

Thanks for the reply. 

I reduced the flux linkage by 10% and its working fine now.
