Abstract

PURPOSE:To reduce the irregular torque and rotation of the DC motor by providing a bypass formed of CR time constant circuit at the motor when the motor is energized and driven by a transistor for smoothing the waveform of drive current. CONSTITUTION:The driving transistor Tr is connected to the DC motor M, a drive 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 time constant circuit having a resistor VR2 and a capacitor C1 is connected in parallel with the motor M, and a bypass is formed. Since the waveform of the driving current of the motor M is thus smoothed to alleviate the abrupt energization control, the irregular rotation and torque and further the noise can be reduced by energizing or deenergizing the transistor Tr.
