Abstract
(EN)
The purpose of the invention is to obtain, in a control device for a synchronous electric motor that switches the drive control of the synchronous electric motor between PWM drive control and rectangular wave drive control, a configuration capable of efficiently driving the synchronous electric motor with consideration given to effects on the rotation speed of the synchronous electric motor. This control device 1 comprises: a PWM signal generating unit 14 that generates a PWM signal; a rectangular wave signal generating unit 22 that generates a rectangular wave signal; a rotation speed detection unit 40 that detects the rotation speed of a motor 2; a signal switching determination unit 50 that determines, in accordance with at least said rotation speed, which of the PWM signal or the rectangular wave signal is to be used as a control signal at the time of controlling the driving of the motor 2; and a drive control unit 30 that controls the driving of the motor 2 by using the signal determined by the signal switching determination unit 50 to be used as the control signal.
