  2. Rating plate - Wikipedia

    en.wikipedia.org/wiki/Rating_plate

    For an electric machine, the power rating is the number on its rating plate and corresponds to a maximum electric load it can carry. There is a distinction between the continuous rating (for generators, continuous maximum rating or CMR [ 2 ] ), at which the machine can be operational without a time limit and short-term rating that can only be ...

  3. Polarity (mutual inductance) - Wikipedia

    en.wikipedia.org/wiki/Polarity_(mutual_inductance)

    Three-phase transformers used in electric power systems will have a nameplate that indicate the phase relationships between their terminals. This may be in the form of a phasor diagram, or using an alpha-numeric code to show the type of internal connection (wye or delta) for each winding. [citation needed]

  4. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field ...

  5. Circle diagram - Wikipedia

    en.wikipedia.org/wiki/Circle_diagram

    The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of a circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero.

  6. Nameplate capacity - Wikipedia

    en.wikipedia.org/wiki/Nameplate_capacity

    Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or gross capacity, [1] is the intended full-load sustained output of a facility such as a power station, [2] [3] electric generator, a chemical plant, [4] fuel plant, mine, [5] metal refinery, [6] and many others.

  7. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

  8. Permanent magnet motor - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet_motor

    A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.

  9. Switched reluctance motor - Wikipedia

    en.wikipedia.org/wiki/Switched_reluctance_motor

    The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
