It is funny how humongous things depend on the proper functioning of teeny tiny things. The existence of small thing is having the significance of what microbes have in the ecosystem. One such particular part is Electric Motor Ac.
It is a motor with Alternating Current (AC). As the name suggests, the flow of current continuously changes its direction. It is like a fun ride in an Amusement Park. Now this changing current impacts the magnetic field and with each change in direction of current the poles of the magnetic field get shifted. It makes the rotor in the motor to move according to the changes in magnetic fields. And that is how an Electric AC Motor works.
But there are different types of Ac motor. First is Induction Motor and the second one is Synchronous Motor.
Induction Motor-electric ac motor
This is the most common form of AC Motor used. It is also called the Asynchronous Motor. This type of motor the torque is produced by the rotor. Traditionally it was used as a Fixed Speed Drives (FSD), but now with the advent of technology, it is now used as Variable Speed Device (VSD). Also some changes have been made to its design so that it can adapt to the varied environments and give performance according to its name – rigid and high power.
Synchronous Motor-electric motor dc
In synchronous motor, their most distinguished feature is that they can run at a constant speed. No matter how much load is being exercised upon them, they can continue to run at the same pace which they were running at. As the name suggests, the synchronisation between the rotor and the stator is the result a constant speed is achieved. To start the synchronous motor, the rotor has to be first moved by an external source. And a momentum is given to the rotor.
