In general, the machine most suitable for use in the industry is the squirrel cage type. Among its advantages, it should be emphasized the reduced cost compared to single-phase motors, not only in their projection, but also in their use. It should be noted that in choosing the ideal start-up process, this type of engine has numerous options for applications. The motor stator is composed of a ferromagnetic core laminated in its cavities, into which are inserted the windings fed by the three-phase AC JML1509T network. The main advantage of the rotor refers to the coiled rotor, which makes the projection of the armature faster, more practical and economical.
The conductor bars of the cage are inserted with an appropriate inclination so as to avoid possible vibrations and noises, which may result in the electromagnetic action between the teeth of the stator and rotor cavities. The squirrel cage rotor is composed of a nucleus of ferromagnetic sheets which are insulated, in which are inserted some aluminum bars, arranged parallel to each other, being connected at their ends by conductive rings, designed in aluminum with the intention of cause short circuits in the conductors.
