MOTOR CONTROLLER

摘要

A control apparatus for an electric motor is obtained, in which current control means 23 for giving multiphase voltage commands to a drive circuit 24 for an inverter 25 includes normal-mode current control means 31 for use in a normal mode, abnormal-mode current control means 30 for use in an abnormal mode, and abnormality decision means 32, and in case of occurring abnormality to one phase of an electric motor or the inverter, the control means is altered, and the abnormal-mode multiphase voltage commands which are generated by the abnormal-mode current control means 30 are set as the multiphase voltage commands for the inverter drive circuit.
