ABSTRACT:
A circuit and method for controlling a rotating or oscillating element of a DC motor, including a positional deviation correction signal generator in addition to a position sensor which detects an amount of rotation or oscillation and position of the rotating or oscillating element, a main control circuit that includes a DC motor driving circuit, and a computer which controls the main control circuit. The output signal of the positional deviation correction signal generator is controlled by the computer based upon positional deviation correction information and signals from the position sensor, so that the positional deviation correction signal generator compensates for any positional deviation of the rotating or oscillating element of the DC motor at a stopping position thereof.
