Definitions:

Electro-Magnets

Devices that create a magnetic field when electric current flows through a coil wrapped around a metal core.

Magnetic Pole Fields

The regions at the two ends of a magnet where the magnetic force is strongest, known as the north and south magnetic poles.

Synchronous Speed Calculation

Synchronous speed calculation is the process of determining the speed at which the magnetic field of an AC motor rotates, which is based on the frequency of the power supply and the number of magnetic poles in the motor.

Locked Rotor Current

The current drawn by an electric motor when the rotor is not turning and power is applied, typically higher than the running current.
