Abstract
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.
