A stator structure of a motor includes a first magnetic substrate, a
second magnetic substrate and a plurality of coil units. An outer profile
of the first magnetic substrate has a plurality of first protruding
parts, and an outer profile of the second magnetic substrate has a
plurality of second protruding parts. The first magnetic substrate and
the second magnetic substrate are correspondingly disposed. The coil
units disposed between the first magnetic substrate and the second
magnetic substrate respectively have a coil wound around a central axis
of the coil unit, and at least one magnetically conductive element
disposed within the coil.
