To understand how an electric motor works, the key is to understand how the electromagnet works. (See How Electromagnets Work for complete details.) An electromagnet is the basis of an electric motor. Say that you created a simple electromagnet by wrapping 100 loops of wire around a nail and...

If you’re an electrical engineer, you know how an electric motor works. If you aren’t, it can be extremely confusing, therefore, here’s the simplified explanation (or the “how an electric motor works for dummies” version) of how a four pole, three phase AC induction motor works in...
How an electric motor works—in practice Universal motors Other kinds of electric motors Find out more How does electromagnetism make a motor move? The basic idea of an electric motor is really simple: you putelectricityinto it at one end and anaxle(metal rod) rotates at the other end givin...
The electric motor connects to a drive wheel by way of a drive belt. The drive wheel rotates the long upper drive shaft, which connects to several different mechanical elements. The end of the shaft turns a crank, which pulls the needle bar up and down. The crank also moves the thread-...
Tools aren't made entirely of carbide partly because it would be very expensive, but also because the tool would be very brittle. Steel is actually a better material for the body of the tool because it is tougher and will not crack or shatter....

A motor works on the same principles, but in the opposite direction -- it converts electrical energy into mechanical energy. To do this, a motor needs a special kind of magnet known as an electromagnet. In its simplest form, this consists of an iron bar wrapped in a coil of wire. If...
This is a huge problem and is one of the reasonselectric vehicles are better for the environment, especially when connected to a clean power source. How Does an AC Induction Motor Work? In simple terms, the AC induction motor works by electrifying conducting copper coils positioned around the ...
