The most common type of rotor is the squirrel cage rotor. The rotor comprises of a cylindrical laminated core with axially placed parallel slots for carrying the conductors. Each slot carries a copper, aluminum, or alloy bar. The rotor of three-phase induction motors frequently is likewise implied as an anchor. The purpose behind this name is the anchor shape of the rotors used within quite early electrical devices.
Induction motor has the same physical stator as a synchronous machine with an alternate rotor development. Induction motor might be worked as either motors or generator. On the other hand, they are fundamentally used as induction motors. Two Types of Induction Motors Single phase induction motor: The single-phase induction motor is not self-starting. When the motor is connected to a single-phase power supply, the main winding carries an alternating current.
It is logical that the least expensive, most reduced upkeep sort engine ought to be utilized most regularly. These are of different types based on their way of starting since these are of not self starting. Those are split phase, shaded pole and capacitor motors. Again capacitor motors are capacitor start, capacitor run and permanent capacitor motors. Permanent capacitor motor is shown below. When the supply voltage is applied, current in the main winding lags the supply voltage because of the main winding impedance.
The angel between the two windings is sufficient phase difference to provide a rotating magnitude field to produce a starting torque. Induction machines are very cheap when compared to synchronous and DC machines. It make them first choice for any operation. It is another advantage of using Induction Machine. Induction machines are no doubt very reliable machines and have considerable efficiency.
Starting torque on induction motor is high which make is useful for operations where load is applied before the starting of the motor. Applications of Induction Machines As I've said Induction motors are used everywhere in our daily life still some of the main advantages are listed below: Induction motors are most common motors used in any kind of Industry including it be an electrical or otherwise. No matter what a company produce but when it comes to a motor it is none other than an Induction motor.
For large operations 3-Phase Induction and for small operations single phase or Fractional Horse Power FHP industion motors are employed. Our home is a place where we can see many Induction motors doing their job. Motor of refrigerator, water pump motor, cooler motor are some of very common examples. You May Also Like:
