Embodiment 1

[0039] Such as Figure 3-11 As shown, Embodiment 1 of the present invention discloses a brushless motor stator. The brushless motor stator includes a stator core assembly 10 and a stator winding 20. The stator winding 20 is wound on the stator core assembly 10. The stator core assembly 10 There are a plurality of winding teeth 11 distributed at intervals along the circumferential direction, and a wire slot 12 is provided between any two adjacent winding teeth 11, and the stator winding 20 is accommodated in each wire slot 12 and wound from each wire slot 12. Set on each winding tooth 11, the stator winding 20 includes several phase windings, each phase winding includes two lead ends, the adjacent lead ends of any adjacent two-phase windings are located in the same slot 12, the brushless motor stator Adjacent lead ends of different phases pass through the same wire slot 12, which simplifies the winding structure of the stator winding 20, making it simple in structure, good in m...

Embodiment 2

[0049] Such as Figure 8-11 As shown, Embodiment 2 of the present invention also discloses another brushless motor stator with winding structure, which is different from Embodiment 1 in that: first lead end 211, second lead end 212, third lead end 221, The fourth lead end 222, the fifth lead end 231 and the sixth lead end 232 are located on one side of the stator core assembly 10, and the first bridge wire 213, the second bridge wire 223 and the third bridge wire 233 are located on the stator core assembly 10. On the other side of the core assembly 10, the bridge wire of the three-phase winding passes through the other side of the stator lead-out wire, and is in a different position from the inlet and outlet wires, effectively avoiding the mutual influence between the two and avoiding the risk of manual threading. The half-turn coil can be increased / decreased, thereby increasing the flexibility of adjusting the number of coil turns.

Abstract

The invention discloses a brushless motor stator and a brushless motor. The brushless motor stator includes a stator core assembly and a stator winding wound on the stator core assembly. Winding teeth, there is a slot between any two adjacent winding teeth, the stator winding is accommodated in each slot and wound on each winding tooth, the stator winding includes several phase windings, each phase winding includes two The adjacent lead ends of any adjacent two-phase windings pass through the same slot. The adjacent lead ends of the adjacent two-phase windings in the brushless motor stator of the above embodiments of the present invention pass through the same wire slot, which simplifies the winding structure of the stator winding, makes it simple in structure, good in manufacturability, and efficient. High, and it is not easy to scratch the bridge wire, which can reduce the risk of inter-turn short circuit.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a brushless motor stator and a brushless motor. Background technique [0002] In automotive motors (low voltage) and low-power industrial motors, 12-slot brushless motors are widely used, among which 12-slot 8-pole matching is the most typical; 12-slot brushless motors with near-pole matching, such as 12-slot 10-pole and 12-slot With 14 poles, it has the advantages of small self-positioning torque, high winding coefficient, good sine degree and high positioning accuracy, and has received more and more attention, especially in the field of low-voltage automotive motors. In order to improve the power index of the motor, especially for brushless motors with an outer diameter of less than 100mm, segmented stator cores are often used to improve the power index of the motor, but this also causes the complexity of the motor manufacturing process, so how to Improving the manufacturing ca...
