Abstract
A motor control apparatus for a three-phase brushless DC motor. The motor control apparatus comprises a power converter which has, for each phase of the brushless DC motor, an electrical half-bridge having two electronic switches, and an application-specific integrated circuit for actuating the electronic switches of the power converter. The application-specific integrated circuit can be controlled by a programmable control unit in a normal mode, has a first interface for receiving an error signal signaling a malfunction and is designed to change the power converter to a defined final operating state independently of the programmable control unit after receiving the error signal.
