Hello Simple FOC Community,
I came across a strange problem that needs a bit of advice on how to resolve it. The hardware setup that I am using is a DRV8302 power driving board connected with an ESP32 microcontroller. First I was using a 52 W 4pp BLDC (Hall sensors) motor running at 24 volts. The motor was working perfectly but it had a low torque of 0.125Nm.
I change the motor to FlipSky 5065, 1500 W 7pp (Hall Sensor) BLDC motor and tried to run that BLDC motor on the same hardware. According to motor specification, it can be run at (11.1- 29.6 V). Now by changing the motor, I am unable to move this motor. I changed all the parameters in the software, i.e. pp value and the Hall sensor is working fine as well. I am running the motor at torque control and whenever I give any voltage value the motor move a bit and start a humming noise. Even during the pole pair search it doesn’t move smoothly and always gives different pp values.
Can someone advise me on how can I make this motor run?
