Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.

Motors & Generators

◆We've all been there - one moment you're watching your favorite program on TV and the next you're in the dark because the power's gone out. At such a time, you may wish you had a candle or a flashlight so that you could see in your dark house. But what would be really useful is a generatorbecause this converts mechanical energy into electrical energy. If the generator were powerful enough, you could use it to restore electricity to your house, at least for a little while◆

◆Now that you know how handy a generator is, you may be tempted to rush to the store and buy one. So, you get in your car and you drive there, pick one up and bring it home. Once you get your power restored, you realize that in the darkness you were clumsy and knocked your dinner plate onto the floor. So, you get the vacuum out and start cleaning it up. At this point you have done an amazing thing - you have essentially reversed what the generator did! Inside the vacuum is an electrical motor, which converts electrical energy into mechanical energy◆

◆While the generator and the vacuum (or any other device powered by a motor) may serve different functions, they are actually two sides of the same coin. In fact, they are the same device! In an electrical motor, the input is electricity and the output is mechanical power. Contrary to this, a generator takes mechanical power and outputs electricity. In both cases, electricity is flowing - just in a different direction!◆

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.
