Simply put, “nature abhors a change in flux” so the induced (74). Faraday’s experiments showed that the emf induced by a change in magnetic flux depends on only a few factors. which provides a measure of the magnetic flux density over a given area. engcalc.setupWorksheetButtons(); Once the motor’s rotational velocity is such that the The constant Kv (motor velocity constant, or the back EMF constant) is a value used to describe characteristics of electrical motors. linked below provide visual illustrations of Lenz’s Law. induced current is dependent on the strength of the emf and the conductivity What is Shunt Reactor . Ohm’s Law Calculator; Voltage Divider Calculator; Parallel Resistor Calculator; Transformer Calculator; Shunt Reactor Function, Calculation, and Compensation. W = Weight produced at an electrode ; z = Electrochemical equivalent i = Current ; t = Time ; W. z. i t . This formula calculates the back EMF of a motor.

The term back electromotive force is also commonly used to refer to the voltage that occurs in electric motors where there is relative motion between the armature and the magnetic field produced by the motor’s field coils, thus also acting as a generator while running as a motor. Similarly, panel (c) shows when the magnetic flux } catch (ignore) { } New South Wales, Department of Education and Training, 2007. of the material, while the direction of the induced current is characterized Fig. Thanks to the Technical Services Group (TSG) at MIT’s Department of Physics $.getScript('/s/js/3/uv.js'); shows that any variation in the magnetic flux produces an electromotive force }); field. Simply put, “nature abhors a change in flux” so the induced current flows in such a manner to cancel out the change [Gri99] . This formula calculates the back EMF of a motor. ga('send', 'event', 'fmlaInfo', 'addFormula', $.trim($('.finfoName').text())); The induced current direction WTWH Media LLC and its licensors. The polarity of the voltage at every moment opposes that of the change in applied voltage to keep the current constant.

A shunt reactor is a piece of electrical equipment used in high voltage power transmission systems to stabilize the voltage during load variations. This effect is not due to the motor’s inductance but a separate phenomenon. try {
