A synchronous motor is an electric motor that has a constant rotational speed. The rotation of the shaft is synchronized with the frequency of the supply current at steady state. The rotation period is exactly equal to an integer number of AC cycles. 

Synchronous motors are used in many devices, including: Clocks, Tape recorders, Phonographs, Maglev trains, Assembly lines, Conveyors, Robotic systems. 

Synchronous motors are smaller and less costly to build than squirrel-cage induction motors of equivalent horsepower. They also lose less energy than induction motors at a given rating. 

Synchronous motors can be classified into two types based on how the rotor is magnetized:
Non-excited synchronous motors: These motors do not need excitation voltage to start and use ferromagnetic materials in their rotors to interact with their stators.
Direct Current (DC) Excited Synchronous Motors: The only major current-excited synchronous motor available is the direct current-excited synchronous motor.
