Improvements in the manufacturing process of magnetic pole coils include the automation upgrade of pure copper busbar ultra-high frequency induction brazing machines.
Regarding insulation materials, the application of J0707 F-grade L-shaped insulation boards eliminates the need for traditional inner and outer support plates, simplifying the motor structure and helping to reduce the height of the motor core and the weight of the magnetic poles.
In terms of structural design, the DC traction motor adopts an integrated insulation structure for the coil and core, which prevents coil loosening and has advantages such as good insulation performance and low temperature rise. The manufacturing process of the magnetic pole coils in the 5GTA-24A3 traction synchronous generator differs from traditional domestic processes.
