Where, n is the synchronous speed, f is the power frequency, p is the number of pole pairs.

Where n is the synchronized rotational speed, f for the power supply frequency, and p is number of pole pairs.

Among them, n is the synchronized rotational speed, f is the supply frequency, p is a number of pole-pairs.

It is therefore continuously changing power supply smoothing the frequency, you can adjust the motor speed.

Where n is the synchronized rotational speed, f for the power supply frequency, and p is number of pole pairs.
