    I'm having a bit of trouble getting a motor to freewheel. If I turn off all six
    fets while the motor is running at full speed, the motor just locks up. I have
    to reset the controller to get it to operate again. The controller and motor
    are operated from separate supplies, so I can't see why the controller would
    drop out.

    Any ideas?

    using for snubbing, or have you not followed the advice from previous
