牙科电钻、电动离心机和骨科电锯等医疗设备中经常使用交直流两用串励式电机。这种电机的转子绕组损坏后重新绕制时比较复杂。我们对绕制方法作了一点改进,效果比较好。在没有动平衡校验机的条件下,采用叠绕法绕制转子绕组,容易产生重心和电流不 Dental drills, electric centrifuges and orthopedic chainsaw and other medical equipment often use AC-DC dual-purpose series motor. This motor rotor winding damage after re-winding more complicated. We made some improvements to the winding method, the effect is better. In the absence of dynamic balance check machine conditions, the winding method winding rotor winding, prone to center of gravity and current is not
