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 ...
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.
An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor.Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.
Robert Dahlander. A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor.
An implementation is described in a whitepaper by Zilog on an ebike hub motor controller [5] for a 200 W, 24 V brushless DC electric (BLDC) motor. [6] P.A.S or PAS may appear within the list of components of electric conversion kits for bicycles, which implies Pedal Assistance Sensor or sometimes Pulse Pedal Assistance Sensor. Pulse usually ...
A man riding an electric kick scooter. A motorized scooter is a stand-up scooter powered by either a small internal combustion engine or electric hub motor in its front and/or rear wheel. Classified as a form of micromobility, [1] they are generally designed with a large center deck on which the rider stands.
On electric power systems, synchronous condensers can be used to control the voltage on long transmission lines, especially for lines with a relatively high ratio of inductive reactance to resistance. [9] In addition to purpose-built units, existing steam or combustion turbines can be retrofit for use as a syncon.
The term scooty has become the generic term for scooter in India [1]. A scooter (motor scooter) is a motorcycle with an underbone or step-through frame, a seat, a transmission that shifts without the operator having to operate a clutch lever, a platform for their feet, and with a method of operation that emphasizes comfort and fuel economy.
