AC Motor- Description and Types

Motor that changes over the alternating current into mechanical power by utilizing an electromagnetic enlistment marvel is called an AC motor. This engine is driven by an exchanging current. The stator and the rotor are the two most vital parts of the AC motor. The stator is the stationary piece of the engine, and the rotor is the turning some portion of the motor. Ac motor might be single phase and three phase.

Three phase AC motors part connected to the industry for mass power transformation from electrical to mechanical. For little power change, the single phase Ac motors are utilized. Single phase AC motor is about little in size, and it gives an assortment of administrations in the home, office, business concerns, manufacturing plants, and so on. All the residential apparatuses, for example, fridges, fans, clothes washer, hair dryers, blenders etc. Are utilize single phase AC motor.
There are two basic types of Ac motors:-
Induction Motors & Asynchronous Motor:- In Induction motor main part is rotating the magnetic field. The most widely recognized wellspring of this in air conditioning motor  is the squirrel confine design. There is basically two rings, one at each finish of the motor, with bars of aluminium or copper interfacing the two closures. AC induction motor  have properties that make them particularly appropriate to various mechanical and additionally home machine applications.
First of all, they are basic and rough engines that are easy keep up. They are keep running at steady speed over an extensive variety of load settings, from zero to full-stack. The main disadvantage is that induction motor they are not agreeable to speed control. Three phase induction motor, would now be able to be speed controlled also.

Synchronous Motor:-  Synchronous motors are work synchronously whatever the recurrence source of there, that’s why they are named it synchronous motor. The engine speed is settled and doesn't change with changes to the heap or voltage. These engines are fundamentally utilized where the necessity is exact and consistent speed. Most synchronous motors are utilized in substantial mechanical applications, with horsepower evaluations running from the low hundreds up to a thousands horsepower.
Synchronous motor can be utilized in movement control applications, however there are some drawbacks to utilizing these motors. As a result of the rotor estimate, the engine's reaction in increasing applications is normally not great. Likewise, on the grounds that increasing speed of inertial burdens may not be as high as other engine composes, these engines may work at unpredictable speeds and deliver bothersome clamour. Synchronous motors are bigger and more expensive than different engines with a similar drive rating.
