A Synchronous motor is fundamentally a fascinating electrical device that synchronizes with the rise and fall of electric currents.
Three-phase synchronous motors find their major application in industrial situations where there is a large, reasonably steady mechanical load, usually in excess of 300 kilowatts, and where the ability to operate at leading power factor is of value. Below this power level, synchronous machines are generally more expensive than induction …
