The temperature of all electrical devices will result as a consequence of the current passing through its conductors. In the case of motors, further temperature increases are brought about as a result of bearing friction, windage (air resistance), and eddy-current/hysteresis losses in the rotor and stator.
Yes the Induction motor works on Electromagnetic induction principle.
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
AC Induction Motor
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.

yes
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
single-phase induction motor is used in ceiling fan.
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
