8-pole 36-slot motor winding coil embedding method suitable for automatic coil embedding

Abstract

The invention discloses a 8-pole 36-slot motor winding coil embedding method suitable for automatic coil embedding, wherein an annular stator is arranged, 36 slots for accommodating windings are uniformly distributed in the circumferential direction of the stator, and the windings are three-phase double-layer windings and are respectively embedded into the 36 slots. The method comprises the following steps: (1) embedding all lower-layer edges of windings, wherein the lower-layer edges are subjected to coil embedding three times, the winds are U1, V1 and W1 three-phase windings, and six coils are connected in series to form each phase winding; and (2) embedding all upper-layer edges of the windings, wherein the upper-layer edges are subjected to coil embedding three times, the winds are U2,V2 and W2 three-phase windings, and six coils are connected in series to form each phase winding. According to the coil embedding method, the problems of large noise vibration and low power density and torque density caused by three-phase inductance imbalance brought by the automatic coil embedding mode of the traditional machine are solved while the difficulty of the traditional machine automatic coil embedding process is reduced, the yield is improved, and the automation efficiency is improved.

technical field [0001] The invention relates to the motor technology industry, in particular to a wire embedding method suitable for automatic wire embedding of an 8-pole and 36-slot motor winding. Background technique [0002] The traditional double-layer fractional slot distribution winding of the motor stator adopts manual embedding. In recent years, with the development of the national economy and science and technology, there has been a machine automatic embedding method, but it is generally used in the integer slot distribution winding. And they all use the method of first embedding U-phase windings, then embedding V-phase windings, and finally embedding W-phase windings. Compared with artificial embedding wires, this method has unbalanced three-phase inductance in terms of performance, and the vibration and noise of the motor is large, and the power density and torque density are low. , Due to the process of inserting the wires one by one phase by phase, when the last...
