Background

At present, a single-layer winding is widely applied to a small three-phase asynchronous motor, the single-layer concentric winding has the characteristics of convenience in wire embedding, wire saving and difficulty in breakdown of in-phase in a slot, and generally, the smaller the number of parallel branches is, the lower the inter-turn risk is, and the smaller the impact of a power supply on a wire inlet part is.

At present, there are two main methods for implementing the number of parallel branches a ═ 1: one is that each polar phase group of the coil is wound singly, and the outside of the wire package is welded during wiring; one is that when winding the coil, each phase of polar phase group is directly connected by a long wire, and in this way, the machine needs to be stopped when winding, and an insulating sleeve is added for the wire; and arranging the long wires in order during wiring.
