1: motor with small load, discontinuous work
Governor must not be lower than 50% of governor

2: Heavy load motor, discontinuous work
Governor should not be lower than 70% of governor

Speed regulation safety zone description:
Why can the speed be adjusted to a certain range after the motor is loaded?
That's because the motor speed is reduced by reducing the voltage. After the voltage is reduced, the torque of the motor will also be reduced, and it is likely to be overloaded.
In addition, after the motor speed is slowed down, the cooling fan will also slow down, and the heat dissipation effect will be worse. At this time, the heat dissipation will become worse due to the increase of the current.
