Summary: | A brushless direct current motor. The brushless direct current motor comprises a rotor, a stator, and a driver. The rotor comprises magnetic poles. The stator is enclosed by or enclosing the rotor. The stator comprises salient poles and at least one permanent magnetic element. The salient poles correspond to the magnetic poles, and the permanent magnetic element is disposed on one of the salient poles to facilitate the rotation of the rotor. The driver is coupled to the stator and produces a primary magnetic field on the salient poles. The rotor is rotated by a secondary salient pole induced by the permanent magnetic element and the primary magnetic field alternately. |
