Abstract
A motor control unit (10) includes: a power converter (40) having a rectifier circuit (20) which rectifies an AC voltage from an AC power supply (31), a capacitor circuit (22) which receives an output of the rectifier circuit (20) and outputs a rectified voltage having pulses from both ends of a capacitor (13) and an inverter circuit (25) which receives the rectified voltage and outputs an AC voltage to the motor (30); and a motor controller (41) controlling the motor (30) by controlling the inverter circuit (25). The motor controller (41) performs torque control to vary an output toque of the motor (30) in response to variation in load torque of the motor (30).
