Description

Technical Field

[0001] The present invention relates to the field of electromechanics, and in particular to a winding die and a continuous winding process for a 4-pole 2-way motor with isolated poles and series coils. Background Art

[0002] When the number of parallel branches of the stator winding of a three-phase asynchronous motor is P, the adjacent pole phases are usually connected in series. When the winding form is concentric winding, the coil is wound with large circles connected to each other, and the wire is placed on the outside of the coil. The coil winding and wire embedding process are relatively simple, but the motor noise is relatively large.

[0003] To reduce motor noise, the windings of a 4-pole, 2-way motor can be connected in series with alternate poles. This reduces noise by 5-7dB compared to windings with adjacent poles in series, while also reducing stray losses. When using the alternate pole series method for concentric windings, the two coils are connected by a large coil and a small coil. This is typically done by welding the two coils in series, which can lead to poor connections. Furthermore, each coil is wound with a consistent head, resulting in wasted copper wire and making it difficult to determine the proper length of the wire. Summary of the Invention
