Please exchange the motor. Is it possible to adjust the speed with a governor?
There are more than one way to regulate speed. The frequency, the magnetic pole, the logarithm and the slip are all right
The frequency changer is the alternating current frequency, so long as the equipment permits, may realize the stepless speed change in principle;The logarithm of the modified pole is a phase change, the variable series is limited, and the slip rate is changed simultaneouslySlip can be changed in a variety of ways, but the range is limitedI don't know which one exactly
Many domestic electric fans use bidirectional thyristor to do phase shift speed regulation. This kind of speed regulation is to reduce the input current so that the motor can not move fast and can only reduce the speed. Like the light desk lamp, it is forced to adjust.
At present, the most preferential speed regulation mode is frequency converter with the best performance, while the output torque is constant at low speed.
