A motor includes a rotor and a stator. The rotor comprises a rotating shaft and an impeller. The impeller couples with the rotating shaft and has a hub. The hub has an outer surface, an inner surface, a plurality of first through holes and a plurality of second through holes. The first through holes are disposed nearer the rotating shaft than the second through holes. The stator comprises a silicon steel sheet and a bearing assembly. The silicon steel sheet has an annular portion and a plurality of protruding portions. The rotating shaft couples with the bearing assembly and penetrates within an inner hole of the annular portion. Each protruding portion is extended outward from the annular portion and has an extending length. The distance between the first through hole and the nearest second through hole is in a range of 0.3 to 1.2 times of the extending length.

Motor

A brake device of a rotating motor is disclosed and includes a base, an upper plate, a sliding plate, a transmission component, a lining plate, a connection element, a planar plate and an elastic component. A rotating shaft runs through the base in an axial direction. The sliding plate is arranged between the base and the upper plate, and driven by the drive module. The transmission component is sleeved and fixed on the rotating shaft, and includes a sleeved peripheral edge, a limiting portion, and a perforation. The limiting portion is protruded outwardly from the sleeved peripheral edge in a radial direction, and the perforation is passed through the limiting portion along the axial direction. The lining plate sleeved on the sleeved peripheral edge is located between the sliding plate and the upper plate. The elastic component is arranged between the planar plate and the limiting portion.

Brake device of rotating motor

A rotary motor stator includes a plurality of stator teeth and a plurality of terminal securing blocks. The stator teeth are arranged in a ring to define a rotor accommodation space. Each stator tooth includes an inner side, a winding section and an outer side. The inner side is closer to the rotor accommodation space than the outer side, and the winding section is located between the inner side and the outer side for winding a coil. Each terminal securing block is fixed to the outer side of each stator tooth, and each terminal securing block includes a first wire slot configured to secure an end of the coil. An angle between a line passing through a center of the ring and a center of each terminal securing block and a lengthwise direction of the first wire slot is an acute angle.

Rotary motor stator

A wiring method of a stator of a rotating electric machine includes: winding m-th layer of a first coil in a first direction from an outer-diameter side toward an inner-diameter side of the stator; winding (m+1)-th layer of the first coil in a second direction opposite to the first direction, a closest distance between n-th layer of the first coil and a centerline is less than a threshold; winding m-th layer of a second coil in the first direction; winding (m+1)-th layer of the second coil in the second direction, the turns of n-th layer of the second coil is equal to the turns of the n-th layer of the first coil minus two; sequentially winding from (n+1)-th layer of the second coil to a final layer of the second coil so as to fill the first wiring region and/or the second wiring region.
