Construction of a three phase induction motor

The three phase induction motor is the most widely used electrical motor. Almost of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction , low cost, good operating characteristics, absence of commutator and good speed regulation. Squirrel cage induction motor and 2. Phase Wound induction motor (slip-ring induction motor ). Both types have similar constructed rotor, but they differ in construction of rotor.

For industrial and mining applications, - phase AC induction motors are the prime movers for the vast majority of machines.

Three phase induction motor construction.

Dragonfly Education is an education company, that is building proprietary education content for higher learning in technical streams. Construction of Stator and Rotor of the Induction Motor is explained in this article. A three phase Induction motor mainly consists of two parts.

The construction of induction motor and induction generator also same.

But for most of the application, its performance as an induction generator is unsatisfactory. In this article we will study about construction of a . For better understanding the principle of three phase induction motor , the basic constructional feature of this motor must be known to us. Note the interleaving of the pole windings and the resulting quadrupole field.

Concept of rotating magnetic field ! An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is induced by electromagnetic.

In most installations, induction motors can be started and brought up to speed by connecting . IM), has been describe when the three - phase balanced winding of the stator is supplied with three - phase balanced voltage. Developments of this design became . But the rotor construction differs with respect to the type which is specified above. Stator: phase winding The stator is the outer most component in the motor which can be seen.

It may be constructed for single phase, three phase or even . Due to the robust construction and ease of control, three - phase asynchronous motors are widely preferred over many other motors for the AC motor driven applications. This three - phase motor is accountable for larger load operations in several applications like goods and lift hoists, conveyors, compressors, pumps, . The rotor is the central component of the motor , and is fixed to the shaft. This configuration is called a squirrel cage rotor because .
