PROBLEM TO BE SOLVED: To provide a brushless motor control device using PAM even in the case of a module for controlling an induction motor. SOLUTION: The power module incorporates a microcomputer for controlling the speed of a DC brushless motor by controlling a three-phase inverter semiconductor switching element and a power supply power factor improvement switching element, and a drive circuit for transferring the signal of the microcomputer, inputs a PWM signal for the induction motor as a speed command from the outside, and fundamental waves are interpreted as a speed command for the brushless motor. |
