During the winding of magnetic pole coils used in synchronous electric motors, cold hardening is induced by press bending at 90°, by which the coils are hard to be pressed and shaped, thus local resistivity increases and results in influence on the coil l

摘要同步电动机磁极线圈在编绕加工时，90℃角处因压弯而产生的冷作硬化现象使线圈无法装压成型，且局部电阻率增大，甚至影响磁极线圈使用寿命。
