Hi everyone,
I have designed a BLDC driver for 24V, 300W BLDC hub motor using Allegro's A3931kjpt IC. my digital inputs are,
PWM freq=20KHz
DIR,COAST,MODE,ESF,BRAKE=1
internal current control with Vref=3.5V
Vdsth=3.5V.
With this setup my motor runs from 0% to 100% duty cycle. But it is not able to provide the torque. Even at 100% duty cycle if I try to stop the motor, it stops.
Can someone suggest me the solution?
