Motors

An electric motor, in general, refers to a device that uses an electric source, either DC or AC power, to create some sort of mechanical motion. In most cases, a rotary motion around a central axis. This is seen in fans, power tools, vacuums, and many other household accessories seen on a daily basis. Motors most often use the power of magnets to create the force required for movement. These magnets come in the form of permanent magnets and temporary electromechanical windings that can be controlled and are the means in which electricity is converted into movement.
Inside a motor are some basic elements that are common throughout the many variations of the technology. The main spinning device is called a rotor, which is attached to the drive shaft that extends out of the motor housing. This is what provides the torque for whatever mechanical use is required. The rotor fits inside a stationary housing called a stator, which is where the electromagnets are located, and all of the wire windings are kept. There are usually many isolated units of windings which allows for more control of the specific timings of the actual magnetic fields. Most motors also have some sort of controller to switch through the windings and provide a smooth driving force for the rotor mechanism.
