Brushless Motor

摘要

A brushless motor includes a stator and a rotor. The stator includes a stator core and two windings. The stator core includes a yoke, two opposing first teeth, and two second teeth. The windings are respectively wound around the two first teeth. The second teeth are not wound with any winding. The first and second teeth are alternatively arranged. The rotor is received in a space cooperatively bounded by the pole shoes of the main and second teeth. Air gaps are formed between an outer circumferential surface of the rotor and respective pole faces of the first teeth and the second teeth. Each of the air gaps is even in radial thickness.

1. A brushless motor comprising:
a stator comprising a stator core and two windings, the stator core comprising:
a yoke;two first teeth connected to the yoke, the winding wound around the two first teeth; andtwo second teeth connected to the yoke, the second teeth avoiding being wound with any winding, the first teeth and the second teeth being alternatively arranged along a circumferential direction of the yoke, each of the first teeth comprising two pole shoes extending in opposite ways along the circumferential direction, each of the second teeth comprising two pole shoes extending in opposite ways along the circumferential direction; a rotor rotatably received in a space cooperatively bounded by the pole shoes with air gaps respectively defined between an outer circumferential surface of the rotor and the pole faces; wherein each of the air gaps is even in radial thickness.
