  3. 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.

  4. Volkswagen Group MEB platform - Wikipedia

    en.wikipedia.org/wiki/Volkswagen_Group_MEB_platform

    The MEB platform is supported by the APP 310 electric motor, which is a permanent magnet brushless motor. Fully developed by Volkswagen, the name "APP" derives from the arrangement of the motor and the gearbox in parallel with the axle, while "310" references its maximum torque of 310 N⋅m (31.6 kg⋅m; 229 lb⋅ft). Maximum torque is achieved ...

  5. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  6. 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 ...

    Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

  8. Electronic speed control - Wikipedia

    en.wikipedia.org/wiki/Electronic_speed_control

    Brushless ESC systems basically create three-phase AC power, like a variable frequency drive, to run brushless motors. Brushless motors are popular with radio controlled airplane hobbyists because of their efficiency, power, longevity and light weight in comparison to traditional brushed motors. Brushless DC motor controllers are much more ...

  9. Power band - Wikipedia

    en.wikipedia.org/wiki/Power_band

    While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range [1] (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output.
