2. Electronic speed control - Wikipedia

   en.wikipedia.org/wiki/Electronic_speed_control

   An electronic speed control follows a speed reference signal (derived from a throttle lever, joystick, or other manual input) and varies the switching rate of a network of field effect transistors (FETs). [1] By adjusting the duty cycle or switching frequency of the transistors, the speed of the motor is changed. The rapid switching of the ...

3. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line-to-ground voltage because it uses less conductor material to transmit a given amount of electrical power. [3] Three-phase power is mainly used directly to power large induction motors, other electric motors and other ...

4. Motor control center - Wikipedia

   en.wikipedia.org/wiki/Motor_control_center

   A small, early 1960s-vintage motor control center for 480 volt motors. A motor control center ( MCC ) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter ...

6. Wound rotor motor - Wikipedia

   en.wikipedia.org/wiki/Wound_rotor_motor

   The speed and torque characteristics of a wound-rotor motor can be adjusted by changing the external resistance, unlike a squirrel cage motor which has a fixed characteristic. This is useful for speed control of the motor. [1] A wound-rotor motor can be used in several forms of adjustable-speed drive. Common applications include hoists and ...

8. 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 ...

9. Direct torque control - Wikipedia

   en.wikipedia.org/wiki/Direct_torque_control

   Direct torque control (DTC) is one method used in variable-frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors.This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor.
