Constructive Aspects of the Rotor

The rotor consists of the following parts: Shaft: In steel, it transmits the mechanical power generated by the motor. It is worked thermally to correct problems such as warping and fatigue; Core: The rotor core can be manufactured with laminated or even solid-formed sheets in a single steel block, there is no need for the plate properties to be identical to the stator, since there is only continuous current circulation in the rotor which does not lead to significant losses in iron; Cage (damping): It is formed by bars and short-circuit rings, normally installed at the ends of the rotor poles or together with the field windings in the case of smooth pole rotor.

Used to break the engine L1319T by applying the same principles of asynchronous induction electric motors. It can be made of electrolytic copper or brass. During the nominal working regime it still has the function of damping sudden changes of load and transients in the network, helping to remain the motor in the synchronism; Field coils: Also called field winding, it consists of a set of coils fed by direct current through the excitation system.
