Example Embodiment
[0015] Example: such as figure 1 As shown, the three-phase motor is composed of a motor shell, a magnetic permeable ring, a winding stator, a permanent magnet rotor, a silicon steel laminate, and a rotating shaft from the outside to the inside. Such as figure 2 with image 3 Each winding stator shown is composed of two semicircular stator frames with ring windings, which can be injection molded with high temperature resistant plastic molds. The formed stator frame is a semicircular structure with an inner cavity, and the outside is wound in a ring line. The two stator skeletons face each other to form a full circle with a cavity. The permanent magnet rotor is wrapped in the inner cavity of the winding stator. There is a gap between the permanent magnet rotor and the stator coil, and the permanent magnet rotor can rotate in the cavity. The winding structure of the stator coil also includes a racetrack-type winding coil. A gap is left at the junction of the two stator frames of...
