Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motor control device for electric vehicle achieving rapid temperature rising of a battery under a low temperature environment. SOLUTION: A harmonic generation control unit 25 inputs a battery temperature detected by a battery temperature sensor 23, and when the detected battery temperature is decided to be lower than a set temperature threshold, superposes a harmonic wave generated by a harmonic generation unit 24 on a torque command value Tr corresponding to a driving force required for a three-phase AC motor 2 input into a current command input unit 11 of a motor control unit 10 to control to superpose the harmonic wave on a battery current flowing from a battery 8 to an inverter 9.
