Abstract

PURPOSE:To eliminate a high withstand and large current capacity rotating speed control element by modulating a switching controller output with a rotating speed controller output, controlling a current switching control element with the modulated output and controlling the rotating speed of a DC brushless motor therewith. CONSTITUTION:When the rotating speed of a rotor 4 is lower than a set rotating speed, a signal 1 is outputted from a rotating speed controller 20, gates 31-36 become open, transistors 11-16 are turned ON or OFF through the gates 31-36 besed on the output of a switching controller 17, and the rotor 4 is rotated. When the rotating speed of the rotor 4 reaches a predetermined rotating speed, a signal O is outputted from the controller 20, and the gates 31-36 become closed. As a result, the transistors 11-16 are turned off, the winding of the motor A is not energized, the rotating speed of the rotor 4 is gradually decelerated, and when it becomes lower than the set rotating speed, the signal 1 is again outputted from the controller 20, and the rotating speed of the rotor 4 is accelerated.
