Abstract:
A motor driving device that drives a motor with an alternating-current power converted from a direct-current power supply, includes an inverter that receives a pulse-width modulation signal and supplies the alternating-current power to the motor, and an inverter control unit that generates the pulse-width modulation signal and supplies the pulse-width modulation signal to the inverter. The inverter control unit reduces the number of pulses of the pulse-width modulation signal generated during a first period within one period of a mechanical angle of the motor to be lower than the number of pulses of the pulse-width modulation signal generated during a second period within the one period of the mechanical angle of the motor. The first period is a period during which a load torque is lower than a load torque during the second period.

Claim (Index 6):
The motor driving device according to  claim 4 , wherein\n the one period of the mechanical angle of the motor is divided into a plurality of periods, and the pulse-number setting unit sets the number of pulses of the carrier wave in each of the periods, the number of pulses of the carrier wave having different values in the different periods.
