Other Parts Discussed in Thread: DRV8353
Dear Team,
We are testing our motor controller based on DRV8353RH in 1x mode. Motor has 27 Poles and hall sensor placed 120 degrees apart.
We could observe noise and oscillations while the motor is running. Also, the noise is more in while rotating in one of the directions when compared to the other direction.
We have tried with 25kHz and 40 kHz PWM with 20%. Board consumes around 1 Amp @ 48V, Motor RPM is around 210.
When we increase the dulty cycle to 40%, the current consumption is increased to 2.4 Amp and the noise is high
Please support us on to resolve this for the smooth motor operation.
With Best Regards,
B.Saravana Vikram.
