If there is an extra winding called the "damper winding" in addition to the field winding.
Then the synchronous motor will operate as a squirrel cage induction motor.
Whats is a damper winding ?
A damper winding is made up of copper bars which are placed in the slots in the pole faces of the rotor.
These are short circuited with the help of end rings in a squirrel cage induction motor.
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
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.
AC Induction Motor
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.
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.
