How permanent magnet synchronous frequency converter works

The power supply of permanent magnet synchronous motor is provided by frequency converter. When starting, the output frequency of frequency converter rises continuously from 0 to the working frequency, and the motor speed rises synchronously with the output frequency of frequency converter. Changing the output frequency of frequency converter can change the motor speed, which […]
