What does a dc motor do

Its movement is produced by the physical behavior of electromagnetism. DC motors have inductors inside, which produce the magnetic field used to generate movement. But how does this magnetic field . The most common types rely on the forces produced by magnetic fields.

You can find DC motors in many portable home appliances, automobiles and types of industrial equipment.

The permanent magnets are stationary, so they are called the stator.

The armature rotates, so it is called the rotor. A motor is an electrical machine which converts electrical energy into mechanical energy. In any electric motor , operation is based on simple electromagnetism. The ceramic bar magnet provides the magnetic field in this simple DC motor.

With the magnet in position, the magnetic field is directed vertically. I had some laboratories about DC motors in my uni. Unlike the demonstration motor above, DC motors are commonly designed with more than two poles, are able to start from any position, and do not have any position where current can flow without producing electromotive power by passing through some coil.

Many common small brushed DC motors used in toys and small . If you are interested in brushless DC motors , then better go to the page about how brushless DC motors work. Exactly how do your convert electricity into movement? How does this work in practice? To find the answer to that, we . All of us has played with magnets and we do know this simple observation.

A dc motor has two magnetic fields, one produced by the field or stator. Usually smaller dc motors use permanent magnets. The second magnetic field is produced by . Research Experience for Teachers. Center for Materails Science and Engineering. Massachusetts Institute of Technology.

Electric motors are everywhere! Motor Design: Steven Leeb, MIT. In your house, almost every mechanical movement that you see around you is caused by an AC (alternating current) or DC (direct current) electric motor.

A simple motor has six parts: Keep Reading Below.
