Flat-type single phase brushless DC motor

摘要

A flat-type single phase brushless direct current (BLDC) motor includes a rotor rotatably fixed to a shaft and having a permanent magnet attached to a lower side thereof; a stator plate installed below the rotor; a plurality of stator cores installed on the stator plate to face the permanent magnet, the stator cores including soft magnetic powder and arranged to be asymmetric with respect to a rotation radial direction of the rotor so as to determine a rotational direction of the rotor; and a multiplicity of coils each being wounded around corresponding one of the stator cores to form a magnetic field toward the permanent magnet.
