Abstract
An EPU includes a first DS and a second DS. The first DS includes a first motor and a first inverter control unit. The second DS includes a second motor and a second inverter control unit. The first motor and the second motor are connected to a propeller via an EPU shaft. The EPU shaft drives and rotates a propeller according to outputs of the motor. The first inverter control unit controls the first motor so that the output of the first motor and the output of the second motor become a same. The second inverter control unit controls the second motor so that the output of the first motor and the output of the second motor become same as each other.
