The Community of Metros Benchmarking Group (COMET), formerly CoMET and Nova groups, is a multinational collection of metro systems focusing on international benchmarking, facilitated by the Transport Strategy Centre (TSC) at Imperial College London. The Community of Metros consist of 42 metro systems in 39 cities around the world.
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 ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

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 .
In 1997, the decision was made to retire them due to rotting floors and holes in the roofs, with ALP44s and Comet IV coaches (ordered for Midtown Direct service) in push-pull configuration as replacements. Most were scrapped in 2001. Pair 1236–1237, renumbered to 601–602, remains (however split) as part of SEPTA's wire inspection train. [2]
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.
