As the number of poles (P) increases, the speed of an induction motor (N) decreases.
As seen by the formula: N=(120*f)/P

What is effect of frequency on induction motor speed?
secret......... They are proportional..
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
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.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
What is the effect of increasing the length of the air gap in an induction motor?
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
What is effect of frequency on induction motor speed?
secret......... They are proportional..
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 3 phase induction motor never atteined sinkronas speed?
Induction motors run at sub synchronous speeds because the slip (difference between synchronous and actual speed) causes, or controls the electric field strength in the motor. As more load is put on the motor, the motor's speed decreases, increasing slip, and increasing the electric field strength.
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Applications of 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.
What is a decripition of Nikola Tesla induction electric motor?
AC 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.
Can a Squirrel Cage Induction motor can be converted to Slip Ring Induction Motor?
yes
