Power factor reduces
overload capacity increased
noise reduces
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.
If Rotor resistance is increased torque is increased

Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.
If Rotor resistance is increased torque is increased
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
As the load increases, the speed reduces to deliver the increased torque required.
Yes the Induction motor works on Electromagnetic induction principle.

The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
If the frequency supplied to a three-phase motor is increased, the motor speed will also increase following the relationship known as the synchronous speed. This increase in frequency will lead to a corresponding increase in motor speed, assuming that the load on the motor remains constant.
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.
