Abstract:
A motor control apparatus, to control a motor based on an instruction phase representing a target phase of a rotor of the motor, includes a phase determiner, to determine a rotation phase of the motor rotor, and a controller having a first control mode to control a drive current flowing through a winding of the motor and a second control mode to supply a current to the winding corresponding to an instruction phase. To reduce a deviation between the instruction and rotation phases, the first control mode results in flowing drive current control based on a rotating coordinate system represented torque current component generating a torque in the rotor. The second control mode results in phase different drive current control first instruction phase. The controller starts the first control mode based on the rotation phase of the rotor determined based on the second instruction phase in the second control mode.

Claim (Index 4):
The motor control apparatus according to  claim 1 ,\n wherein the controller includes a detector configured to detect the drive current flowing through the winding, wherein the first control mode is a control mode to control the motor by controlling a value of an exciting current component of the drive current detected by the detector to be set to 0 and controlling a value of the torque current component of the drive current detected by the detector, and wherein the exciting current component is a current component represented in the rotating coordinate system and affecting an intensity of a magnetic flux penetrating the winding.
