Motor knowledge
Ⅰ.Ordinary asynchronous motors are designed according to constant frequency and constant voltage, which can not fully meet the requirements of variable frequency speed regulation. The following is the
The unit of rotational speed is round per minute r/m (rpm), round per second per r/s (rps).ⅰ.Synchronous speed of motorBecause the rotation of the induction motor is caused by the rotating magnetic fi
