The electric motor control apparatus comprises a PAM controlled motor selecting unit (53) for determining which of \"control pattern 1\" and \"control pattern 2\" should be executed by comparison in total power loss, where a voltage control unit on the power generation side (51) performs voltage transformation with a PWM control in a first inverter (30) and generates a drive voltage for a second electric motor (12) with a PAM control in a second inverter (31) in the control pattern 1 and a voltage control unit on the driving side (52) outputs a rectified voltage from a generated voltage of a first electric motor (6) without voltage transformation in the first inverter (30) and generates a drive voltage for the second electric motor (12) with a PWM control in the second inverter (31) in the control pattern 2.",
