Electromagnetism : Parts of AC motors and generators

Hello dummies all around the world. It's glad to see you all in here. Well take a second to look at your house ceiling fan,kitchen blander,air conditioner and electrical tools. You see that all the things you see will rotate when you plug in. What cause these things rotate when gives power. Just be thankful that your house fan,blander and so on rotate by AC motor. AC motor is a cool thing to know how its works and the application. Before we see how AC motor works, Well it's good know the parts of AC motor and AC generator. So lets get started.

AC motor as you can see in your ceiling fan,blander and so on plays important role to make you easy to use and handle it. The parts of AC motor as simple to understand. Lets look at it.

1. Stator 

 Stator is the main part of the AC motor.Stator is made of windings that attach with the motor's body. Stator provide rotating magnetic field to the rotor. The stator will supply by single phase or three phase to make rotating magnetic field.

2. Rotor

 Rotor is the rotating part of the motor and also main part of the motor. When the stator energize with rotating magnetic field,these will induced the rotor to make it's own magnetic field to rotate. The rotor made of laminated core and space bar of aluminum and copper are short circuit at end of the rotor.

3.Frame/Yoke

The body of motor is called frame or yoke. The frame made of heavy duty steel help to protect the internal parts of motor. The frame acts as earthing for the body.

4.Bearing

Help to reduce friction

5.Cooling Fan

help to dissipate heat from getting the motor hot.

AC generators has same parts of AC motors,but it has also some different parts also. Lets look at it.

6. Slip ring

 In AC generators, slip ring is used to transmit generator mechanical energy into electrical energy. Each slip ring is attach with brushes, when the rotor rotates, the brush will receive electrical signal from slip ring that connect from stator winding and send to some electrical power lines and appliance.

7. AC/DC exciters

To provide AC/DC to the generator field windings.In generator,stator will be energize with AC or DC. This will induce the rotor to make electrical energy.

THIS IS THE INTRODUCTION OF AC MOTOR AND AC GENERATOR. IN UPCOMING POST, WE GOING TO LEARN HOW MOTORS WORK FIRST!!!.
