Abstract
A motor driver with a fail-startup fast restarting mechanism. The motor driver includes a locking circuit and a motor driving circuit. The locking circuit sets a plurality of locking times during which a motor enters a locked state. In particular, the locking circuit sets at least one of the locking times to be different from other ones of the locking times. The motor driving circuit stops trying to start up the motor within each of the plurality of locking times.
Claims19
A motor driver with a fail-startup fast restarting mechanism, comprising:
- a locking circuit, configured to set a plurality of locking times during which a motor enters a locked state, wherein at least one of the plurality of locking times is different from others in terms of locking time duration;
- and
- a motor driving circuit, connected to the locking circuit and the motor, and configured to attempt to start the motor during one or more non-locking times other than the plurality of locking times, and to stop attempting to start the motor during each of the plurality of locking times.
wherein the motor driving circuit is configured to cut or remove frequency bands of at least one waveform of the startup pattern waveform signal that are generated during the locking time, to form the startup waveform signal.
