2. 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 ...

3. 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 ...

4. Solectria Corporation - Wikipedia

   en.wikipedia.org/wiki/Solectria_Corporation

   Solectria offered a line of electric vehicle drivetrain components, including traction motors with different technologies (AC induction, DC brushless and brushed permanent magnet), the accompanying motor controllers, reduction gearboxes, battery chargers, and DC-to-DC converters (to operate existing 12V parts and accessories using the high-voltage storage battery).

5. DC motor - Wikipedia

   en.wikipedia.org/wiki/DC_motor

   The motor speed varies as a non-linear function of load torque and armature current; current is common to both the stator and rotor yielding current squared (I^2) behavior [citation needed]. A series motor has very high starting torque and is commonly used for starting high inertia loads, such as trains, elevators or hoists. [2]

6. Motor drive - Wikipedia

   en.wikipedia.org/wiki/Motor_drive

   Another way of changing speed of a direct current motor is to change the voltage applied to the armature. An adjustable-speed motor drive might consist of an electric motor and controller that is used to adjust the motor's operating speed. The combination of a constant-speed motor and a continuously adjustable mechanical speed-changing device ...

7. 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 ...
