  2. Brushless DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushless_DC_electric_motor

    A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.

  3. Axial flux motor - Wikipedia

    en.wikipedia.org/wiki/Axial_flux_motor

    An axial flux motor (axial gap motor, or pancake motor) is a geometry of electric motor construction where the gap between the rotor and stator, and therefore the direction of magnetic flux between the two, is aligned parallel with the axis of rotation, rather than radially as with the concentric cylindrical geometry of the more common radial ...

  4. Honda EV Plus - Wikipedia

    en.wikipedia.org/wiki/Honda_EV_Plus

    As an example, the Honda EV project's powerplant team began working with battery manufacturers, proposing a battery format and size that were later adopted as a global standard. [1] In addition, they began developing their own DC brushless motor, since commercially available motors were not efficient enough.

  5. Motor constants - Wikipedia

    en.wikipedia.org/wiki/Motor_constants

    The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...

  6. Synchronous motor - Wikipedia

    en.wikipedia.org/wiki/Synchronous_motor

    Small synchronous motor with integral stepdown gear from a microwave oven. 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. Electric machine - Wikipedia

    en.wikipedia.org/wiki/Electric_machine

    A motor controller converts DC to AC. This design is simpler than that of brushed motors because it eliminates the complication of transferring power from outside the motor to the spinning rotor. An example of a brushless, synchronous DC motor is a stepper motor which can divide a full rotation into a large number of steps.

  8. Reluctance motor - Wikipedia

    en.wikipedia.org/wiki/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 .

  9. Brush (electric) - Wikipedia

    en.wikipedia.org/wiki/Brush_(electric)

    For certain types of electric motors or generators to function, the coils of the rotor must be connected to complete an electrical circuit. Originally this was accomplished by affixing a copper or brass commutator or 'slip ring' to the shaft, with springs pressing braided copper wire 'brushes' onto the slip rings or commutator which conduct the current.
