  2. Linear actuator - Wikipedia

    en.wikipedia.org/wiki/Linear_actuator

    A linear motor is functionally the same as a rotary electric motor with the rotor and stator circular magnetic field components laid out in a straight line. Where a rotary motor would spin around and re-use the same magnetic pole faces again, the magnetic field structures of a linear motor are physically repeated across the length of the actuator.

  3. Load factor (electrical) - Wikipedia

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

    In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...

    Electrical installations in residential buildings – Part 1: Planning principles: Active: DIN 18015-2: Electrical installations in residential buildings – Part 2: Nature and extent of minimum equipment: Active: DIN 18015-3: Electrical installations in residential buildings – Part 3: Wiring and disposition of electrical equipment: Active ...

  5. Motor constants - Wikipedia

    en.wikipedia.org/wiki/Motor_constants

    If two motors with the same and torque work in tandem, with rigidly connected shafts, the of the system is still the same assuming a parallel electrical connection. The K M {\displaystyle K_{\text{M}}} of the combined system increased by 2 {\displaystyle {\sqrt {2}}} , because both the torque and the losses double.

  6. Traction motor - Wikipedia

    en.wikipedia.org/wiki/Traction_motor

    This assumes that the electrical generator converts 90% of the engine's output into electrical energy and the traction motors convert 90% of this electrical energy back into mechanical energy. [citation needed] Calculation: 0.9 × 0.9 = 0.81 Individual traction motor ratings usually range up 1,600 kW (2,100 hp).

  7. Variable-frequency drive - Wikipedia

    en.wikipedia.org/wiki/Variable-frequency_drive

    Regenerative AC drives have the capacity to recover the braking energy of a load moving faster than the designated motor speed (an overhauling load) and return it to the power system. [ 92 ] Cycloconverter, Scherbius, matrix, CSI, and LCI drives inherently allow return of energy from the load to the line, while voltage-source inverters require ...

  8. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  9. Premium efficiency - Wikipedia

    en.wikipedia.org/wiki/Premium_efficiency

    Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...
