Problems solved by technology
And because the cross-sectional shape of the circular magnet wire is circular, there will be a large air gap when the turns are piled up and wound.
Conventional dipping and curing methods cannot effectively and fully fill these large air gaps, so that the existence of these air gaps affects the heat generated by the magnetic pole windings of the synchronous generator. Turn-to-turn problems caused by shifting between turns, eventually leading to winding burnout very quickly

The invention discloses a method for manufacturing a circular electromagnetic wire magnetic pole winding, which comprises the steps of S1: firstly brushing the part to which a circular electromagneticwire is to be wound with an adhesive when the wire is started to be wound after the clamping of a magnetic pole core, and then starting to wind in turn; S2, brushing the surface of the wound wire turn with the adhesive every time when a layer of coil is wound; S3, packing the magnetic pole winding with a demoulding tape and installing solidification clamping plates after the whole magnetic pole winding is wound, and then placing the magnetic pole winding in an oven for curing; and S4, conducting relevant electrical tests after the whole magnetic pole is cured and demoulded. The method disclosed by the invention is simple and safe in structure and very obvious in effect; and the method not only can avoid inter-turn problems appeared in coil winding, but also greatly helps to reduce the temperature rise of the magnetic pole winding and significantly improves the reliability of the motor operation.
Description
technical field [0001] The invention belongs to a method for manufacturing a magnetic pole winding of a circular electromagnetic wire, which can be applied to all related products involved in winding a magnetic pole coil with a circular electromagnetic wire. Background technique [0002] In recent years, diesel synchronous generators have been widely used in ships, trains, etc. In most cases, the rotor magnetic poles of diesel synchronous generators are directly wound on the magnetic pole cores with square electromagnetic wires. But sometimes according to product design needs, large-scale circular enamelled windings are used to wind directly on the pole core. Large-sized round enameled wire is used for winding. Due to the large size and hardness of the electromagnetic wire, it is not suitable to wind tightly between the turns when the turns are wound. Moreover, since the cross-sectional shape of the circular magnet wire is circular, there will be a large air gap when the t...
