STEPPING MOTOR CONTROL DEVICE, OPTICAL APPARATUS, STEPPING MOTOR CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE RECORDING MEDIUM

摘要

A stepping motor control device includes a position detection sensor configured to detect a rotation position of a stepping motor, a voltage controller configured to drive the stepping motor, an advance angle controller configured to control an advance angle that is a phase difference between an excitation current applied to a coil of the stepping motor and the rotation position of the stepping motor, and a speed controller configured to control a drive speed of the stepping motor. The speed controller controls the drive speed using, in combination, voltage control by the voltage controller and advance angle control by the advance angle controller.

主权项

1. A stepping motor control device for controlling a stepping motor, comprising:
a position detection sensor configured to detect a rotation position of the stepping motor; a voltage controller configured to apply a voltage to the stepping motor to drive the stepping motor; an advance angle controller configured to control an advance angle; and a speed controller configured to control a drive speed of the stepping motor, wherein the speed controller is configured to control the drive speed using first acceleration control in which the advance angle is increased by the advance angle controller while voltage is held constant by the voltage controller, and using second acceleration control in which voltage is increased by the voltage controller and the advance angle is reduced or is held constant by the advance angle controller.
