Abstract:
An apparatus, to control a motor from an instructed phase indicating a motor rotor target phase, includes a detector, a phase determiner, a converter, and a controller. The detector detects a motor winding driving current. The phase determiner determines a rotor rotation phase from the detected driving current. The converter converts a detected current value in a stationary coordinate system into a current value in a rotational coordinate system from the determined rotation phase. The controller includes a first mode for controlling the driving current to cause a determined phase deviation between the instructed and rotation phases to decreased, and a second mode for controlling the driving current from a current having a previously determined magnitude. On switching the mode from the second to the first mode, the first mode target value is set from a driving current value corresponding to a current component represented by the rotational coordinate system.

Claim (Index 18):
An image forming apparatus to form an image on a recording medium, the image forming apparatus comprising:\n an image forming unit configured to form the image on the recording medium; a motor configured to drive load; a detector configured to detect a driving current flowing through a winding of the motor; a phase determiner configured to determine a rotation phase of a rotor of the motor based on the driving current detected by the detector; and a controller including a first control mode for controlling the driving current in a manner that a magnitude of the driving current detected by the detector becomes a target value set in a manner that a phase deviation between an instructed phase indicating a target phase of the rotor of the motor and the rotation phase determined by the phase determiner is decreased, and a second control mode for controlling the driving current based on a current having a previously determined magnitude, wherein, in a case where the control mode for controlling the driving current is switched from the second control mode to the first control mode, the target value in the first control mode is set based on a value of the driving current detected by the detector during execution of the second control mode.
