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.
A position control circuit for controlling a position of a moving element of a DC motor, said position control circuit comprising a position sensor which detects an amount of movement and position of said moving element of said DC motor, a main control circuit which includes a DC motor driving circuit, and a computer coupled to said position sensor, said computer controls said main control circuit for controlling a position of said moving element of said DC motor by means of signals from said position sensor, wherein said position control circuit further comprises a positional deviation correction signal generator which compensates for any positional deviation of said moving element in a stopping position thereof, and an output signal of said positional deviation correction signal generator is controlled by said computer based upon positional deviation information and signals from said position sensor.
A method for controlling a position of a moving element of a DC motor, said method comprising:
