In using, the secondary winding can not be short-circuited or operating over-load.
使用时二次绕组不能短路及超负荷运行。
2
Reactive stepping motor rotor windings without, the excitation of the stator winding reacts to achieve step operating torque.
反应式步进驱动电机的转子无绕组，由被励磁的定子绕组产生反应力矩实现步进运行。
3
Once the motor reaches near design operating speed, the centrifugal switch activates, opening the contacts and disconnecting the startup winding from the power source.
