  2. Shunt (electrical) - Wikipedia

    en.wikipedia.org/wiki/Shunt_(electrical)

    A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. It is typically used to divert current away from a system or component in order to prevent overcurrent .

  3. Excitation (magnetic) - Wikipedia

    en.wikipedia.org/wiki/Excitation_(magnetic)

    a shunt, the simplest design, uses the main winding for the excitation power; an excitation boost system (EBS) is a shunt design with a separate small generator added to temporarily provide an energy boost when the main coil voltage drops (for example, due to a fault). The boost generator is not rated for permanent operation;

  4. Shunt generator - Wikipedia

    en.wikipedia.org/wiki/Shunt_generator

    Generator separately excited by battery Self exciting generators Series on left, shunt on right. A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited).

  5. Shunt equation - Wikipedia

    en.wikipedia.org/wiki/Shunt_equation

    The Shunt equation (also known as the Berggren equation) quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung.. “Shunt” and “dead space“ are terms used to describe conditions where either blood flow or ventilation do not interact with each other in the lung, as they should for efficient gas exchange to take place.

    The motor size constant ) and motor velocity constant ... is primarily used to calculate the armature current for a given torque demand: = The SI units for the torque ...

  7. Critical field resistance - Wikipedia

    en.wikipedia.org/wiki/Critical_field_resistance

    In a DC shunt generator, the voltage induced across the armature, V a, is directly proportional to the flux acting across it, The flux in a DC generator is directly proportional to the field current, I f. The critical field resistance is defined as the maximum field circuit resistance (for a given speed) with which the shunt generator would ...

  8. Open-circuit test - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_test

    The parallel shunt component on the equivalent circuit diagram is used to represent the core losses. These core losses come from the change in the direction of the flux and eddy currents. Eddy current losses are caused by currents induced in the iron due to the alternating flux.

  9. Current sensing - Wikipedia

    en.wikipedia.org/wiki/Current_sensing

    Shunt resistor. The common and simple approach to current sensing is the use of a shunt resistor. That the voltage drop across the shunt is proportional to its current flow, i.e. ohm's law, makes the low resistance current shunt a very popular choice for current measurement system with its low cost and high reliability.
