Title: Apparatus and method for controlling motor
Inventor: ISHII HIROSHI
IPC: H02P6/08
Filed: 2001-06-21
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of torque shock arising from mode transition as much as possible for the improvement of the operation characteristics of a motor. SOLUTION: An apparatus and a method for controlling the motor involve a current control means. In fixed mode wherein the rotation speed of a rotor is lower than specified for very low speed, the current control means computes rotor phase using a fixed value within a detected phase angle. In estimation mode wherein the rotation speed of the rotor is higher than the above specified value, the current control means computes rotor phase from a detected phase angle by interpolation. Based on the computed rotor phase and a target torque, the current control means computes a current applied to the stator coils.  The control means judges transition from the fixed mode to the estimation mode for rotor phase computation, and, when the transition is judged, controls a current applied to the stator coils so that the motor torque in the fixed mode and the motor torque in the estimation mode matches each other or gradually vary. Thus, torque shock arising from mode transition is prevented from occurring.
