Operation of Three Phase Induction Motors

The three-phase induction machines are composed of extremely relevant components, being they, the rotor and the stator and we can say that the rotor is produced from elements such as the axis, whose main objective is to perform the proper transmission of the mechanical power produced by the engine.

The stator features a casing, which sits on a support structure that features a strong cast iron, injected aluminum or finned steel construction, and is capable of withstanding weathering such as corrosion. The stator also has three-phase winding, which is made up of three identical coil assemblies, one of which is designed for each phase, thus forming a three-phase system connected to a three-phase power network.

It has a core of sheets, produced in magnetic steel, that are thermally treated and prepared to reduce the possible losses of iron. It is designed with thermal support so that it can prevent possible problems in its performance, such as warping or fatigue, for example.

In it there is also the plate core, which provides specifications similar to the plates contained in the stator. The rotor also has short-circuit bars and rings, usually designed in die-cast aluminum in one piece.
