Synchronous Motor

A type of AC motor that operates at a speed directly proportional to the frequency of the current supply.

Power Factor Correction

Adding capacitance or inductance to a circuit to cause the current and voltage to become more in phase with each other.

Synchronous Condenser

A term used to describe a synchronous motor that is used to provide power factor correction.

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.
