DRV10970: motor speed & torque

Part Number: DRV10970

Hi:

      I want to ask about the DRV10970, now ,I drive the motor at 30 rotations per second, but the torque is very small, and it stops with slight load. Sometimes the 5s can be restored, and sometimes it stops completely. I need to increase the power by myself,How do you solve this problem?

  • Can you provide a little more information?

    What are the characteristics of the motor (motor resistance, Kt, inductance)?
    Does the motor always restart after 5 seconds?
    Does the RD signal go high when the motor stops?
    Can you provide the current waveform for phase U?

    Thanks,
    Brian
