置。[Claim for Utility Model Registration] In a motor speed control device that changes the speed of a motor by chopping, the voltage level of a back electromotive force according to the motor load during chopping. The motor speed is controlled at a duty according to the motor load by comparing the amplified level with a predetermined level and the level of the sawtooth wave from the sawtooth wave generator. Motor speed control device.
