摘要： A stator tooth includes an arc-shaped stator yoke portion and a stator tooth portion. The arc-shaped stator yoke portion extends along an arc having an axis as a center. The stator tooth portion includes a tooth body segment and two shoe-shaped structures. The tooth body segment, protruding along a centripetal axis from the arc-shaped stator yoke portion, has a first inner arc-shaped edge defined with a first center and a first radius. The centripetal axis passes through a center point of first inner arc-shaped edge, the first center and the axis. The two shoe-shaped structures extend oppositely, but symmetrically, from the tooth body segment, and each the shoe-shaped structure has a second inner arc-shaped edge and an inner-edge end point. The second inner arc-shaped edge, extending from the first inner arc-shaped edge to the inner-edge end point, has a second radius larger than the first radius.

摘要： A rotor structure with a suppress harmonic substructure includes a rotor body furnished with magnet-setting areas surrounding a circular center and magnets disposed individually in rotor body. Each magnet-setting area has first and second magnet slots, extended obliquely and symmetrically to a radial axis of the circular center. Outer ends of the first and second magnet slot are disposed adjacent to the radial axis and a rotor's outer rim of the rotor body, and inner ends of the first and second magnet slots are disposed away from the radial axis and the rotor's outer rim. The rotor's outer rim is furnished with main cavities, first and second auxiliary cavities. The radial axis corresponding to one magnet-setting area penetrates through the corresponding one main cavity, and one first auxiliary cavity and one second auxiliary cavity in the same magnet-setting area are disposed to opposite sides of the corresponding main cavity.

摘要： A rotor structure includes a rotor body and a plurality of magnets. The rotor body has a plurality of surrounding magnet-setting areas, and each magnet setting area has a first magnet slot and a second magnet slot symmetrically arranged to a centripetal axis. A first outer end of the first magnet slot and a second outer end of the second magnet slot are close to the centripetal axis and rotor's outer edge. A first outer end of the first magnet slot and a second outer end of the second magnet slot are distant to the centripetal axis and rotor's outer edge. The outer edge has a plurality of notches intersected by the corresponding centripetal axes. The magnets are respectively fixed to the first magnet slots and the second magnet slots of the magnet-setting areas.

摘要： A method includes: forming a sand core including a main portion and core-head members connecting the main portion; applying a casting process to produce a frame casting having a first end, a first-end inner wall, a second end, a second-end inner wall, a closed water channel between the first-end inner wall and the second-end inner wall, a water inlet, a water outlet and sand-expelling holes at the first end; shaking the frame casting to have part of the sand core to leave the closed water channel via the water inlet, the water outlet and the sand-expelling holes; pressurizing a fluid into the closed water channel via the water inlet to carry the rest of the sand core to leave the closed water channel via the sand-expelling holes and the water outlet; and applying screw bolts to lock the sand-expelling holes to manufacture a closed-type and liquid-cooling motor frame.
