Wire embedding method for 8-pole 36-slot motor windings suitable for automatic wire embedding

Abstract

The invention discloses a wire embedding method for an 8-pole 36-slot motor winding suitable for automatic wire embedding, which comprises a ring-shaped stator, 36 slots for accommodating windings are evenly distributed in the circumferential direction of the stator, and the windings are three The phase double-layer windings are embedded in 36 slots respectively; (1), all the lower layers of the windings are embedded first, and the lower layers are embedded three times, which are U1, V1, W1 three-phase windings, and each phase winding consists of 6 The coils are formed in series; (2), all the upper layers of the re-embedded windings are embedded three times, which are U2, V2, W2 three-phase windings, each phase winding is formed by 6 coils connected in series. The wire embedding method of the invention solves the problems of large noise and vibration, low power density and low torque density caused by the unbalanced three-phase inductance caused by the automatic wire embedding method of the traditional machine. At the same time, the difficulty of the traditional machine automatic embedding process is reduced, the yield is improved, and the automation efficiency is improved.

Description

technical field [0001] The invention relates to the motor technology industry, in particular to a wire embedding method for an 8-pole 36-slot motor winding suitable for automatic wire embedding. Background technique [0002] The traditional double-layer fractional-slot distributed winding of the motor stator is manually embedded. In recent years, with the development of the national economy and science and technology, the automatic machine-embedding method has appeared, but it is generally used in integer-slot distributed windings. And all adopt the method of inserting U-phase winding first, then inserting V-phase winding, and finally inserting W-phase winding. Compared with artificial wiring, this method has unbalanced three-phase inductance, high motor vibration and noise, and low power density and torque density. , In the process, due to the phase-by-phase insertion, multiple stator slots are blocked by the coils of the other two phases when the last phase is inserted, wh...
