APPAREIL ET PROCEDE POUR DETECTER ET EMPECHER UN MOUVEMENT D'UN MOTEUR DANS UN DISPOSITIF D'UN SYSTEME
A motor drive system configured to detect and prevent undesired movement of an item that is configured to be driven by the motor drive system. The motor drive system having: an electronic control unit operatively coupled to a rotor of the motor drive system, the electronic control unit being configured to detect undesired rotation of a shaft of the rotor, wherein the undesired rotation of the shaft is not caused by a force applied by the rotor; and wherein the electronic control unit of the motor drive system is configured to short windings of the motor drive system after a predetermined amount of undesired rotation of the shaft is detected by the electronic control unit such that further rotation of the rotor is prevented.
