The term "magnetic pole coil" is an electrical engineering term published in 1998, referring to the conductive winding wound around a magnetic pole in a DC or synchronous motor, and is included in the first edition of *Electrical Engineering Terminology*.
Technological developments involve improvements in insulation structures, such as the "integrated" insulation structure of the coil and core in F-class traction motors; optimization of manufacturing processes, such as the manufacturing process of the magnetic pole coil for the 5GTA-24A3 traction synchronous generator and the automation upgrade of the pure copper busbar ultra-high frequency induction brazing machine; and testing technologies for inter-turn insulation in large motors. Related patents include those related to winding devices, insulation structures, and manufacturing methods.
