    Abstract: PURPOSE: An emergency driving method of a permanent magnet synchronous motor in case of the malfunction of a control system for the motor and a current sensor are provided to drive the motor in an emergency situation without the feedback current of the motor. CONSTITUTION: A voltage command calculator(31) calculates and outputs an emergency synchronous voltage command for controlling a permanent magnet synchronous motor based on a current command from the current command map of a torque command. A switching unit(32) selects the emergency synchronous voltage command or a synchronous voltage command and provides the selected command to a coordinate converter.

    Abstract: An apparatus for cutting off resurrection current is provided to prevent high voltage component due to the regenerative current prevents damage by stopping signal transmission to an inverter and triode when the motor controller has a trouble. An apparatus for cutting off resurrection current includes more than two triode AC switches(152,154) and a motor controller(140). The triode is connected to the cable between the inverter(142) and the motor(160). A motor controller performs drive and regenerative braking of the motor, it controls the on/OFF of the triode. The motor controller supplies a successive pulse voltage to the triode AC switches in the normal control state, and it turns the triode AC switches on and turns the triode AC switches off in abnormal state.
