The Douvrin family is an all-aluminum inline-four automobile engine designed in the early 1970s and produced from 1977 to 1996 by Compagnie Française de Mécanique, a joint-venture between PSA and Renault located in the town of Douvrin in northern France.
The motor size constant and motor velocity constant (, alternatively called the back EMF constant) are values used to describe characteristics of electrical motors. Motor constant [ edit ]
The British Rail Class 84 was a 25 kV AC electric locomotive that operated on the West Coast Main Line (WCML) of the London Midland Region.. The ten strong class was one of five prototype classes of electric locomotives built in the early stages of WCML electrification.
Either an AC motor or a DC motor can operate as a generator that is driven by the unit under test or a motor that drives the unit under test. When equipped with appropriate control units, electric motor/generator dynamometers can be configured as universal dynamometers. The control unit for an AC motor is a variable-frequency drive, while the ...

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.

The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
