The synchronous motor has zero starting torque and must be run up to operating speed by an external drive (inherently not self starting). When the rotor poles are almost in synchronism with the rotating  field produced by the stator, they pull into step and then the rotor runs at synchronous speed.

Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.
