Title:
モータ制御装置及び画像形成装置
Document Type and Number:
Japanese Patent JP7381316
Kind Code:
B2
Abstract:
To provide a motor control technique capable of shortening a period of stopping an application of voltage to a coil.SOLUTION: A motor control device has voltage control means for controlling voltage applied to a plurality of coils of a motor, current detection means for detecting current values of a plurality of coils, and control means for performing setting processing for setting a detection timing of making the current detection means detect the current values by flowing current to a first measurement coil within a plurality of coils by controlling the voltage control means and making the current detection means detect a current value of the first measurement coil at each of a plurality of candidate timings, flowing current to a second measurement coil within a plurality of coils by controlling the voltage control means, and making the current detection means detect the current value of the second measurement coil at each of a plurality of candidate timings, and performing detection processing making the current detection means detect the current values of a plurality of coils according to the set detection timing.SELECTED DRAWING: Figure 8
