Studies by Heinrich Lenz

It is important to emphasize that the scientist Heinrich Lenz could publicly conclude that the electric current induced had the capacity to produce different effects opposite to its causes. Therefore, Lenz established that the direction of induced electric current occurs so that the magnetic field caused by it opposes the variation of the magnetic field that generated it. Some time later, it was proved that this formulation of Lenz’s law is basically a cause and an effect that opposes the cause. This involved cause is nothing more than the variation of the flow that cuts the conductor. The involved effect referred to is a current, due to the induced voltage, that the field opposes to the cause.

Thus, from a somewhat broader point of view, in all cases of electromagnetic induction, without any exception, whenever a variation in the concatenated flux occurs, a voltage must be induced mrosupply, causing it to automatically tend to establish a current in one direction, which will produce a field as opposed to the variation of the flux that concatenates the turns of the circuit. In addition to the one that the scholar Michael Faraday demonstrated, it appeared to the law of Lenz, founded by the physicist Heinrich E. Lenz.

Indispensable Elements of Operation

It should be noted that the rotor can have two or even more windings, considering that they are always even number and all properly connected in series, taking into account that each existing winding is responsible for the production of one of the poles of the electromagnet. In most of the synchronous motors, the rotor can be composed of a permanent magnet in place of an electromagnet, known as a permanent magnet synchronous machine.

Therefore, the stator, also referred to as armature, consists of the fixed part of the machine, designed in the vicinity of the rotor so that it is able to rotate in its interior, which is formed by a combination of blades of a ferromagnetic element wrapped in a set of windings, which is properly distributed around its circumference and inserted into grooves.

The stator windings are fed through a three-phase alternating voltage system baldor CL1304. Throughout the circumference of the stator circulates all the electric energy produced, being that the voltage and the electric current that circulate, are elevated with respect to the rotor, whose objective is only to produce a magnetic field to excite the machine in a way that induces tensions at the terminals of the stator windings.
