Miniature motor structure

A miniature motor structure, comprising:

• a base with a sleeve;
• a stator disposed around the sleeve and further comprising;
• a first coil seat, including a first bottom plate, a plurality of first outer teeth, a plurality of first inner teeth, said first bottom plate further including a first central opening, said first outer teeth protruding from said first bottom plate and surrounding an outer periphery of said first bottom plate, said first inner teeth protruding from said first bottom plate and surrounding said first central opening;
• a coil, formed in the first coil seat;
• a second coil seat, including a second bottom plate, a plurality of second outer teeth, a plurality of second inner teeth, said second coil seat disposed on the first coil seat, said second bottom plate further including a second central opening, said second outer teeth protruding from said second bottom plate and surrounding an outer periphery of said second bottom plate, said second inner teeth protruding from said second bottom plate and surrounding said second central opening, each of said second outer teeth interposed between said adjacent first outer teeth, each of said second inner teeth interposed between said adjacent first inner teeth with the tops of the second inner teeth extending to the same plane of the first bottom plate and the tops of the first inner teeth extending to the same plane of the second bottom plate;
• a circular magnet, surrounding said stator;
• and
• a metal housing, surrounding said circular magnet.

A miniature motor structure, comprising:

• a stator, further comprising:
• a first coil seat, including a first bottom plate, a plurality of first outer teeth, a plurality of first inner teeth, wherein said first inner teeth and said first outer teeth are alternately arranged;
