Abstract
A brushless motor includes a two-phase winding stator having 4×n winding poles and auxiliary poles provided between the winding poles, and a rotor constituted by 6×n permanent magnet rotating poles having divided angle. The two-phase brushless motor can be driven by a control device for the two-phase motor which can transform electric power and rectify electronically. The two-phase brushless DC motor can increase a permeance coefficient of the rotor, improve the efficiency and the starting of the motor, and reduce torque ripple and noise thereof.
