摘要： A stepper motor controlling apparatus has a driver which drives a stepper motor in response to an input pulse signal, a PWM controlling section which changes a duty ratio of the pulse signal fed to the driver to control a rotation of the stepper motor, a pulse encoder which rotates in response to the rotation of the stepper motor, and outputs a pulse according to a position of a moving object, a position counter which counts the pulse output from the pulse encoder to sense a present position of the moving object, and a pulse rate controlling section which controls an update latency time of the pulse signal according to a deviation between a target position of the moving object and the present position.
