Definitions:

Synchronous Speed

The speed at which the magnetic field in an AC machine rotates, typically in motors or generators, determined by the machine's electrical frequency and the number of magnetic poles.

Rotor Speed

The rotational speed of the rotor in a motor or generator, typically measured in revolutions per minute (RPM).

Percent Slip

In an induction motor, the difference between the synchronous speed and the actual rotor speed, expressed as a percentage of the synchronous speed.

Three-Phase Motor

An electric motor that operates on three phases of alternating current, offering smoother and more efficient operation than single-phase motors for high-power applications.
