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.
How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
Theory for brake test on three phase induction motor?
why three phase induction motor is delta connected
What is the derivation of Torque and power equation of induction motor?
Torque is the cross product of radius and force .Torque is a twisting effect. Torque is the cross product of radius and force .Torque is a twisting effect.
What are the different types of induction motors?
DOL(Direct Online starting) Star Delta starting Auto transformer starting Above methods are for squirrel cage induction motor Rotor resistance starting is used for wound rotor or slip ring induction motor
What is the effect of increasing number of poles on the speed of an induction motor?
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 are the End effects in linear induction motor?
due to the finite length of primary core and windings of linear induction motor, the phenomenon so produced is called as end effect. this can be categorized further as dynamic end effects and exit end effects.
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.
What is effect of frequency on induction motor speed?
secret......... They are proportional..
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
