  2. Induction motor - Wikipedia

    en.wikipedia.org/wiki/Induction_motor

    Induction motors are most commonly run on single-phase or three-phase power, but two-phase motors exist; in theory, induction motors can have any number of phases. Many single-phase motors having two windings can be viewed as two-phase motors, since a capacitor is used to generate a second power phase 90° from the single-phase supply and feeds ...

  3. 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.

  4. 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.

  5. Squirrel-cage rotor - Wikipedia

    en.wikipedia.org/wiki/Squirrel-cage_rotor

    By adjusting the shape of the bars in the rotor, the speed-torque characteristics of the motor can be changed, to minimize starting current or to maximize low-speed torque, for example. Squirrel-cage induction motors are very prevalent in industry, in sizes from below 1 kilowatt (1.3 hp) up to tens of megawatts (tens-of-thousand horsepower).

  6. Synchronous motor - Wikipedia

    en.wikipedia.org/wiki/Synchronous_motor

    When = 90° the torque will be maximum. If load is applied further then the motor will lose its synchronism, since motor torque will be less than load torque. [44] [45] The maximum load torque that can be applied to a motor without losing its synchronism is called steady state stability limit of a synchronous motor. [44]

  7. Linear induction motor - Wikipedia

    en.wikipedia.org/wiki/Linear_induction_motor

    A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects ...

  8. Power band - Wikipedia

    en.wikipedia.org/wiki/Power_band

    In this case, unless external limitations are applied, the maximum torque is achieved at low RPM. For example, the AC motor found in the Tesla Roadster (2008) produces near constant maximum torque from 0 to about 6000 RPM, while maximum power occurs at about 10000 RPM, long after torque begins to drop off. The Roadster's redline is 14000 RPM.

  9. FAM control of induction motor - Wikipedia

    en.wikipedia.org/wiki/FAM_control_of_induction_motor

    To obtain very quick torque control response in induction motor, it is required to suppress electromagnetic transients which might be caused by the control. Then it is necessary to investigate the electromagnetic transients of an induction motor. Within the induction motor, the largest inductance is the exciting inductance of exciting reactance.
