Zusammenfassung:	PROBLEM TO BE SOLVED: To properly perform a protection processing of a coil in a multi-phase motor which has a temperature sensor in at least one phase and no temperature sensor in at least one phase.SOLUTION: When a multi-phase motor MG2 has a temperature sensor 72 in at least one phase (V phase) and no temperature sensor 72 in at least one phase (U phase and W phase) and when the motor MG2 flows current in a motor lock state in which rotation of the motor is stopped, a motor controller displaces a rotor of the motor MG2 to get a rotation phase range in which an absolute value of current flowed in the phase (V phase) having the temperature sensor 72 is an absolute value of current flowed in the phase (U phase and W phase) not having the temperature sensor 72 or more.
