ータの制御装置。 A rectifier circuit that converts alternating current to direct current, an inverter that converts the output of this rectifier circuit to alternating current of any frequency, and the output of this inverter is passed through the armature winding to rotate the permanent magnet rotor. A control device for a brushless motor includes a voltage detection circuit that detects the DC voltage and a current detection circuit that detects the DC current flowing through the inverter, and inputs the output of the voltage detection circuit and a current command value to a multiplier. A control device for a brushless motor, characterized in that the inverter is subjected to PWM control based on the deviation value between the output of the multiplier and the output of the current detection circuit, and the current flowing from the rectifier circuit to the inverter is controlled.
