  2. Dahlander pole changing motor - Wikipedia

    en.wikipedia.org/wiki/Dahlander_pole_changing_motor

    A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor. The motor may have fixed or variable torque depending on the ...

  3. 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 .

    en.wikipedia.org/wiki/Bioconcentration

    Fugacity and BCF relate to each other in the following equation: = [6] where Z Fish is equal to the Fugacity capacity of a chemical in the fish, P Fish is equal to the density of the fish (mass/length 3), BCF is the partition coefficient between the fish and the water (length 3 /mass) and H is equal to the Henry's law constant (Length 2 /Time 2) [6]

  6. Synchronous motor - Wikipedia

    en.wikipedia.org/wiki/Synchronous_motor

    Synchronous motor. Miniature synchronous motor used in analog clocks. The rotor is made of permanent magnet. A synchronous electric motor is an AC electric motor in which, at steady state, [ 1] the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integer number of AC cycles.

  7. Carrier lifetime - Wikipedia

    en.wikipedia.org/wiki/Carrier_Lifetime

    Carrier lifetime. A definition in semiconductor physics, carrier lifetime is defined as the average time it takes for a minority carrier to recombine. The process through which this is done is typically known as minority carrier recombination . The energy released due to recombination can be either thermal, thereby heating up the semiconductor ...

  8. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A drawing meant to depict the physical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram. Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.

  9. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices. A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to ...
