Abstract: A motor stator includes an insulating frame having a plurality of projecting rods, an induction unit, and a plurality of conductive members. The induction unit includes an induction circuit board, a plurality of induction coils embedded within the induction circuit board, and a plurality of coil windings wound respectively on the projecting rods. The conductive members extend through the insulating frame and the induction circuit board for establishing an electrical connection between each of the induction coils and a corresponding one of the coil windings. The turn numbers of the coil windings are not limited by the area and thickness of the induction circuit board, and can be increased. Alternatively, the coil windings may be positioned to increase the magnetic pole slot number when energized. As such, a driving force of the motor stator can be increased.
