An AC induction motor relies on a Rotating Magnetic Field (RMF) created by the stator windings. This field induces a current in the rotor, causing it to spin. The speed of the RMF is known as the synchronous speed, calculated by the formula:

The ultimate standard for AC speed control. VFDs convert incoming AC power to DC, smooth it, and then invert it back into a simulated AC sine wave with adjustable frequency and voltage (maintaining a constant Volts-per-Hertz ratio). 4.
