Title:
モータ制御装置及び画像形成装置
Document Type and Number:
Japanese Patent JP6953289
Kind Code:
B2
Abstract:
To provide a motor control device capable of making a motor control correspond to a vector control system.SOLUTION: A motor control device estimates each of an A/D converter detecting a current value on a ground side of a driving circuit that drives a plurality of motors having two phase windings and an induction voltage occurring in each phase winding of each motor on the basis of the current value detected by the A/D converter. An electric angle is detected on the basis of the induction voltage estimated, and a vector control is performed on the basis of the electric angle detected and a micro-step pulse inputted into the driving circuit. The motor control device generates a PWM signal for controlling a switching element of the driving circuit, and executes the vector control by correcting a detection result from the A/D converter on the basis of a variation component of the A/D converter premeasured.SELECTED DRAWING: Figure 2
