1. a system, it comprises:

  • There is the motor of multiple motor winding;

    Be coupled to multiple brake switches of described motor winding, described brake switch by described motor winding coupled to common electrical force;

    Be coupled to the sensor of described motor, described sensor provides the sensing signal of the parameter indicating described motor;

    WithController, speed-slackening signal is provided to described brake switch selectively to control described brake switch with motor winding described in short circuit in response to described sensing signal by it.
