  2. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    At around the same time, PWM started to be used in AC motor control. [ 4 ] Of note, for about a century, some variable-speed electric motors have had decent efficiency, but they were somewhat more complex than constant-speed motors, and sometimes required bulky external electrical apparatus, such as a bank of variable power resistors or ...

  3. Electronic speed control - Wikipedia

    en.wikipedia.org/wiki/Electronic_speed_control

    An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking . Miniature electronic speed controls are used in electrically powered radio controlled models .

  4. Motor controller - Wikipedia

    en.wikipedia.org/wiki/Motor_controller

    A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...

  5. DC motor - Wikipedia

    en.wikipedia.org/wiki/DC_motor

    A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

  6. Brushed DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    Generally, the rotational speed of a DC motor is proportional to the EMF in its coil (= the voltage applied to it minus voltage lost on its resistance), and the torque is proportional to the current. Speed control can be achieved by variable battery tappings, variable supply voltage, resistors or electronic controls.

  7. Chopper (electronics) - Wikipedia

    en.wikipedia.org/wiki/Chopper_(electronics)

    Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors.

  8. 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.

  9. Ward Leonard control - Wikipedia

    en.wikipedia.org/wiki/Ward_Leonard_control

    The key feature of the Ward Leonard control system is the ability to smoothly vary the speed of a DC motor, including reversing it, by controlling the field and hence the output voltage of a DC generator, as well as the field of the motor itself. As the speed of a DC motor is dictated by the supplied voltage, this gives simple speed control ...
