Description

Technical Field

[0001] The invention relates to a magnetic pole excitation coil of a generator rotor, in particular to an insulation wrapping method for a multi-turn copper flat wire excitation coil. Background Art

[0002] Since the high-speed synchronous generator has a small number of rotor poles, the excitation coil of each pole is generally wound with a copper flat wire with a relatively large width and height ratio, and the copper flat wire must be wound along the narrow side for multiple turns. During the winding process, the coil corners are prone to flipping and the external insulation layer of the wire is cracked. Therefore, various motor manufacturers generally use bare copper flat wire for winding. After the coil is wound and formed, the excitation coil is insulated turn by turn. However, since the coil is in the shape of a spiral spring after winding, the adjacent turns of the coil are tightly stacked together, which makes it difficult to perform the insulation wrapping turn by turn and the wrapping efficiency is very low. How to develop an insulation wrapping tool for the coil to achieve convenient insulation wrapping of the spiral coil has become an urgent problem to be solved on site. Summary of the invention
