Induction motor comprised inductor as the most part in it and an inductor has the characteristic to oppose the change of current, i.e., it has lagging power factor as current lags behind the voltage. Hence, an induction motor works on lagging power factor.

Application of induction motor in industry?
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
When induction motors is used for power factor correction what is called?
I'm not sure I've ever seen an induction motor used to correct power factor; it is usually the induction motors that are causing the poor power factor. "Power factor correction" is usually accomplished by adding capacitors to the system to counteract the inductance of large motors.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
Why the no load power factor is quite small in case of 3-phase induction motor?
Induction motors are designed for a certain power. If the power demand is lower than that, you still have to setup the magnetic fields as if you were going to supply that maximum power. As a result, the no-load power factor of an induction motor is quite small, i.e. poor.
When the length of air gap is increased in an induction motor what will also increase?
Power factor reduces overload capacity increased noise reduces
What is the effect of induction motor on power factor?
An induction motor has a lagging power factor. Motors of more than about 2 HP are designed to have a power factor of 0.85 or higher.
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.

Difference between transformer and 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.

Load test on 3 phase induction motor?
When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
Why the no load power factor is quite small in case of 3-phase induction motor?
Induction motors are designed for a certain power. If the power demand is lower than that, you still have to setup the magnetic fields as if you were going to supply that maximum power. As a result, the no-load power factor of an induction motor is quite small, i.e. poor.
Why the induction motor power factor is poor at no laod?
If the power demand is lower than that, you still have to setup the magnetic fields as if you were going to supply that maximum power
When is efficiency of 3phased Induction motor maximum what is the condtion for maximum efficiency in induction motor?
It is maximum at about 75% to 100% of the motor rated load. Efficiency is maximum at unity power factor , when R=X and when variable losses Is equal to constant losses at rated load.
