The large brown molded-plastic piece in the foreground supports the brush guides and brushes (both sides), as well as the front motor bearing. A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator.
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
The word armature was first used in its electrical sense, i.e. keeper of a magnet, in mid 19th century. [3] The parts of an alternator or related equipment can be expressed in either mechanical terms or electrical terms. Although distinctly separate these two sets of terminology are frequently used interchangeably or in combinations that ...

As early as 1834, he developed a battery-powered electric motor, along with his wife Emily Davenport. They used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. [2] It is the first attempt to apply electrification to locomotion.

A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1] Typical applications include electric motors, alternators and electric generators. The lifespan of a carbon ...
Electrical apparatus that regulates and protects an electric motor, which may be as simple as an on-off switch or a servo system for precision machine tools. motor soft starter A device that reduces the inrush current when an electric motor is first connected to the power supply. MP3 A standard for encoding audio in digital form. MRI
