Description

Technical Field

[0001] The present invention relates to the technical field of direct current motors, and in particular to a motor winding frame and a winding structure. Background Art

[0002] refer to Figure 1 At present, the 12-slot 10-pole brushless DC motor straight stator winding in the air-conditioning industry adopts the concentrated winding method. The 1st, 6th, 7th, and 12th slots are U phases, the 2nd, 3rd, 8th, and 9th slots are V phases, and the 4th, 5th, 10th, and 11th slots are W phases.

[0003] The connecting wires between slots 1 and 6, slots 7 to 12, slots 8 to 3, and slots 5 to 10 are long, which are easy to loosen and fall out of the frame after the stator is rounded, causing wire breakage and breakdown. To solve this problem, a crossover wire is added to slots 4, 9, 5, and 8 respectively;

[0004] This winding structure solves the loose wire problem, but the following problems still exist:

[0005] Since the added cross-over wire is pressed by the slot winding, the winding is subjected to a large extrusion force during injection molding, which makes it easy for the cross-over wire to short-circuit with the slot winding and cause poor turn-to-turn connection.

[0006] Since all the connecting wires between phases are concentrated on one side of the frame, there are more connecting wires on the outside of the frame, and there are two-phase leads at the same slot outlet, which can easily cause phase-to-phase short circuit and turn-to-turn problems.
