Title:
ブラシレスモータ、外部交流電圧源および電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP5752275
Kind Code:
B2
Abstract:
The present invention provides a brushless motor in which the voltage utilization ratio can be increased and the torque and output of the motor can thereby be increased, and also provides a drive method for a brushless motor. The brushless motor includes an armature constituted by an armature core having armature windings of a plurality of phases, and a field pole constituted by a field pole core having a plurality of permanent magnets. A voltage, in which at least a 5th order harmonic component is superimposed on a 1st order fundamental wave of a voltage under predetermined phase difference condition and amplitude condition in order to increase a 1st order fundamental wave peak of the applied voltage over an applied voltage peak, is applied to the armature windings.
