Title: Control circuit and control method of stepping motor and image forming device
Inventor: TOMINAGA HIDEKAZU
IPC: H02P8/14
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To suppress the natural vibration of a stepping motor, eliminate periodic pitch unevenness and improve an image quality. SOLUTION: A supplied current detecting means 3 detects a current supplied to a motor driving means 2. A 1st filter means 5 extracts a current ripple with a natural frequency from the supplied current. A 2nd filter means 6 further smoothes the current ripple with the natural frequency and extracts the average value of the current ripple. From a difference between the extraction result of the 1st filter means 5 and the extraction result of the 2nd filter means 6, the fluctuation value of the current ripple is extracted and fed back to the set value of a current setting means 4 and supplied to the driving means 2 to complete a feedback loop and the deviation from a target value is converged upon zero.  If a stepping motor begins resonance with its natural frequency by an external disturbance, by the detection of an error between the target value and the actual value, the feedback loop operates so as to suppress the resonance of the natural vibration.
