モータ制御装置、シート搬送装置及び画像形成装置
Document Type and Number:
Japanese Patent JP7080700
Kind Code:
B2
Abstract:
A motor control apparatus includes a detector configured to detect a drive current, a phase determiner configured to determine a rotation phase of a rotor of a motor, and a controller provided with a first control mode for controlling the motor by controlling the drive current flowing in a winding of the motor so as to reduce a deviation between an instructed phase and the rotation phase, and a second control mode for controlling the motor based on a current having a predetermined magnitude. The controller decelerates the rotor after switching a control mode for controlling the motor from the first control mode to the second control mode in a state where the rotor is being rotated at a predetermined speed based on the first control mode.
