Difference between Induction motor and Synchronous motor

The induction motor does not require an excitation system to start motor. The Synchronous Motor requires the DC excitation system (or prime mover) to start the motor (i.e. for the rotor rotating). The motor is cheap, especially cage rotors and maintenance-free. The motor is costly and requires frequent maintenance.
