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.)
electrical equipment Apparatus for generation, transmission or utilization of electric power. electrical grid A geographically distributed system to connect source and users of electric power. electrical impedance That property of a circuit that resists the passage of electric current, usually in the context of alternating current.
Electrical engineering in this context also encompasses electronics engineering. Electromechanical devices are ones which have both electrical and mechanical processes. Strictly speaking, a manually operated switch is an electromechanical component due to the mechanical movement causing an electrical output.
Motors: Electric motors use either AC or DC electric current to generate rotational movement. Electric servomotors are the actuators for mechanical systems ranging from robotic systems to modern aircraft. Fluid Power: Hydraulic and pneumatic systems use electrically driven pumps to drive water or air respectively into cylinders to power linear ...
By 1914, the IEC had issued a first list of terms and definitions covering electrical machinery and apparatus, a list of international letter symbols for quantities and signs for names of units, a list of definitions in connection with hydraulic turbines, and a number of definitions and recommendations relating to rotating machines and ...
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism.
