Electrical machine that converts electrical energy into mechanical energy.
An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
Sum of potential energy and kinetic energy.
Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a heat engine converts heat to mechanical energy.
The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors or biological rotors.
Interconnection of electrical components or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances).
Practical examples of such sources include a battery or a generator.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator.
Electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction.
In a power plant, energy is generated at a convenient voltage for the design of a generator, and then stepped up to a high voltage for transmission.
Vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
Rotating magnetic fields are used in both electric motors and generators.
Difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
Electric potential differences between points can be caused by the build-up of electric charge (e.g., a capacitor), and from an electromotive force (e.g., electromagnetic induction in generator, inductors, and transformers).
A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field.
