Abstract

PURPOSE:To reduce the irregular torque and rotation of the DC motor by connecting a resistor to the motor when the motor is driven by energizing the driving transistor and applying a pedestal current thereto. CONSTITUTION:The driving transistor Tr is connected to the Dc motor M, driving pulse is applied to the base terminal of the transistor Tr, the transistor Tr is thus energized or shut off, and the motor M is driven. In this case a bypass having a resistor VR1 is provided in the motor M, a pedestal current is applied to the motor M, and a DC component may always flow therethrough. Accordingly, the pedestal component is added to the pulse wave, and the operation of energizing and deenergizing the motor M can be alleviated. Consequently, the irregular rotation, torque and noise can be reduced.
