synchronous motor and induction motor || Difference Between Synchronous Motor And Induction Motor

synchronous motor and induction motor || Difference Between Synchronous Motor And Induction Motor-AC motors can be divided into two main categories - (i) Synchronous motor and (ii) Asynchronous motor. An asynchronous motor is popularly called as Induction motor. Both the types are quite different from each other. Major differences between a synchronous motor and an induction motor are discussed below.
Constructional Difference
Synchronous motor: Stator has axial slots which consist stator winding wound for a specific number of poles. Generally a salient pole rotor is used on which rotor winding is mounted. Rotor winding is fed with a DC supply with the help of slip rings. A rotor with permanent magnets can also be used.
Induction motor: Stator winding is similar to that of a synchronous motor. It is wound for a specific number of poles. A squirrel cage rotor or a wound rotor can be used. In squirrel cage rotor, the rotor bars are permanently short-circuited with end rings. In wound rotor, windings are also permanently short-circuited, hence no slip rings are required
