    • A control device controls an inverter controlling an output of a motor by PWM control. The control device calculates a reference frequency (fs) based on a torque and a rotation speed of the motor, calculates a random coefficient (α) using two data tables, and calculates, as a random frequency (fr), a value obtained by adding, to a reference frequency (fs), a value obtained by multiplying a prescribed width (W1) by the random coefficient (α). The control device calculates control limit lines (L1, L2) based on the rotation speed of the motor, and corrects the random frequency (fr) so as to fall within a range that is higher than the control limit line (L1) and lower than the control limit line (L2). The control device generates a carrier signal (CR) having a random frequency (fr) as a carrier frequency.
