ELECTRIC MOTOR CONTROL APPARATUS |
摘要 |
A control apparatus for a multiphase AC electric motor having an inverter, wherein a current control means (23) comprises an abnormal-state current controlling means (30) that is used during any abnormal state; an abnormal-state determining means (32) that determines any abnormal state of a wire of an electric motor (5) or a wire of an inverter (25) or a wire connecting the electric motor with the inverter; and an abnormal phase disconnecting means (34). The abnormal phase disconnecting means disconnects one or more of abnormal phases determined by the abnormal-state determining means from the circuit, and the abnormal-state current controlling means generates an abnormal-state voltage command in accordance with an abnormal state determined by the abnormal-state determining means, and uses phases other than the disconnected phases of the inverter to perform individual current controls of the phases with the abnormal-state voltage command used as a multiphase voltage command. |
