Abstract
A motor structure includes a stator and a rotor. The stator includes a coil assembly which includes a ring-shaped slot having an inner periphery on its inner side and an outer periphery on its outer side away from the inner periphery, a plurality of first teeth mounted around the inner periphery of the ring-shaped slot, and a plurality of second teeth mounted around the outer periphery of the ring-shaped slot; wherein each of the first teeth is arranged to partly fall behind or exceed the corresponding one of the second teeth, and a coil wound in the ring-shaped slot. The rotor includes a circular magnet located above the coil.
Claims16
A motor structure comprising:
- a stator, comprising:
- a coil assembly, including:
- a ring-shaped skit having an inner periphery on its inner side and an outer periphery on its outer side away from said inner periphery
- a plurality of lint teeth mounted around said inner periphery of said ring-shaped slot;
- and
- a plurality of second teeth mounted around said outer periphery of the ring-shaped slot, wherein each of said lint teeth is arranged to partly trail behind said corresponding second tooth in a circumferential direction of said ring-shape slot;
- and
- a coil wound in said ring-shaped slot, and
- a rotor including a circular magnet located above said coil.
