A motor and a rotor structure thereof are disclosed. The rotor structure includes a rotor core. The rotor core has a plurality of magnetic member units arranged around a periphery of the rotor core. Each magnetic member unit includes two first magnetic members and a second magnetic member. The two first magnetic members are obliquely arranged in a V shape relative to a center of the rotor core. The second magnetic member extends transversely between the two first magnetic members. Each first magnetic member has at least two permanent magnets that are arranged obliquely. The motor further includes a stator core covering the rotor core. The stator core has a plurality of stator windings arranged annularly. The stator windings correspond to the magnetic member units. The rotor structure has high structural strength, and the phenomenon of stress concentration is less obvious when the motor is running.

Motor and rotor structure thereof

A motor includes a base, a winding assembly and a rotor. The base includes a pivoting portion. The winding assembly includes a support. The support includes at least one coil supporting portion and a circuit supporting portion connected to the at least one coil supporting portion. A coil is arranged on each of the at least one coil supporting portion. A circuit is arranged on the circuit supporting portion and electrically connected to the coil or coils. A folding portion is arranged between the at least one coil supporting portion and the circuit supporting portion. The circuit supporting portion and the at least one coil supporting portion are folded and stacked together via the folding portion. The rotor is rotatably coupled to the pivoting portion of the base. Due to the arrangement of the folding portion, a radial width of the motor is efficiently reduced.

Motor and winding assembly thereof

The present invention provides a motor winding assembly including a flexible base plate and a winding assembly. The flexible base plate includes a plurality of supports. A bridge is connected between adjacent two of the plurality of supports. Each of the plurality of supports has a center, and the flexible base plate has a reference line extending through the centers of the plurality of supports. The bridge is not located on the reference line. The winding assembly includes a plurality of winding units. Each of the plurality of supports is provided with at least one winding unit. An electrical path is located on the bridge between the adjacent two of the plurality of supports and electrically connected to the winding units of the adjacent two of the plurality of supports. In this arrangement, the total length of the flexible base plate is reduced.

Motor winding assembly

A motor winding structure includes a base plate is disclosed. The base plate includes a board having a winding unit. The winding unit includes a plurality of coils formed on the surface of the board by electroforming or layout. Each coil has a center, and includes an inner end adjacent to the center and an outer end distant to the center. Two adjacent coils are connected to each other via the inner ends. The winding unit further includes an insulating layer and a conducting layer. The inner ends of the two coils are connected to an electrical connection pad. The insulating layer is arranged on the board. The two adjacent coils are covered by the insulating layer. The conducting layer extends through the insulating layer and is connected to the electrical connection pads of the two coils. The two coils are connected to each other via the inner ends.
