Can ac motors be used to speed control?
Only the frequency converter motor can be used to adjust the speed of the transducer, and the ordinary motor can not be adjusted by the transducer. But it's ok to start ac motors with a frequency converter. Because when the speed is low, the ventilation of the electric motors deteriorates, and the fever is severe enough to keep working.
If you don't have a low frequency field running, you can choose to ordinary asynchronous motor, if there is a low frequency operation that suggest you still choose frequency conversion motor, is mainly ordinary motor cooling fan is connected to the motor spindle, fan heat dissipating capacity of low frequency, then the heat dissipation of the motor can't guarantee. But the frequency conversion machine is the opposite, because the fan is controlled separately, it is forced wind cold. It doesn't matter even at low frequencies. I hope I can help you.
Hello, the question is first to determine what is your use and how to speed it up.I hope my answer will help you.
