CA 2531545

The present invention relates to a two-phase brushless DC motor which can increase a pemerance coefficient of a rotor to the maximum to thereby improve efficiency and starting feature of the motor, and to reduce torque ripple and noise thereof. The brushless motor of the present invention comprises 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 identical divided angle. The two-phase brushless motor of the present invention can be driven by a control device for the two-phase motor which can transform electric power and rectify electronically.
