Title:
MOTOR
Document Type and Number:
Japanese Patent JP2019201490
Kind Code:
A
Abstract:
To reduce noise and vibration.SOLUTION: In a motor that produces different magnetic resistance between one and the other of magnetic poles, a stator coil includes two sets of three-phase coils that are individually supplied with current. Coils U1, U2, V1, V2, W1, and W2 of each of phases of the two sets of three-phase coils are symmetrically arranged with an electrical angle of 180° as a boundary. Through a coil corresponding to each of the two sets of three-phase coils, a fundamental wave component of the same period is passed, and the current value of each of the phase coils of two sets of three-phase stator coils is set according to the electromagnetic force generated by the difference in the magnetic resistances of the magnetic poles.SELECTED DRAWING: Figure 2
