In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to electricity.
Electrical equipment part of the distribution system in a large building. Electrical equipment includes any machine powered by electricity. It usually consists of an enclosure, a variety of electrical components, and often a power switch. Examples of these include: Lighting; Major appliance; Small appliances; IT equipment (computers, printers etc.)
Electric, incl. electrically heated gas, laser or other light or photon beam, ultrasonic, electron beam, magnetic pulse or plasma arc soldering, brazing or welding machines and apparatus, whether or not capable of cutting; electric machines and apparatus for hot spraying of metals, metal carbides or cermets; parts thereof (excl. guns for ...
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.
Comparison of pictorial and schematic styles of circuit diagrams Common schematic diagram symbols (US symbols) The circuit diagram for a four-bit TTL counter, a type of state machine. A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit.
One example of these still used today is the alternator, which was created to power military equipment in the 1950s and later repurposed for automobiles in the 1960s. Post-war America greatly benefited from the military's development of electromechanics as household work was quickly replaced by electromechanical systems such as microwaves ...
The term "electric fluid" was based on the idea that a jar could be filled and refilled when it became empty. [3] That led to the revolutionary idea of "electrical fire" as a type of motion or current flow rather than a type of explosion. [36] Several 18th-century electric terms were derived from his name.
