Wound rotor motors appear very complex however, basically are the same thing like the AC Induction Motor of standard type. The rotor gets its power from the process of inductions and utilizes some kind of changeable external resistance for adjusting start-up speed and current. The benefit to search for the problem of wound rotor motor is you can differentiate three primary components for isolating quickly from each other about the main reason of any type of electrical anomaly. The three primary components are the resistor bank, stator and rotor.
The connection between the rotor and stator within a wound rotor is similar to a basic to secondary connection within a transformer. Any change in the rotor circuit that contains the resistor bank, would be marked on the stator or primary. The opposite is correct also in these anomalies on the stator which would be found on the rotor or secondary circuit. You should not come to a conclusion that the windings of the stator are faulty while a top inductive inequity is located on the windings of the stator. Tracking of carbon between failed resistor or malfunctioning contacts and slip rings inside the resistor bank might be the main reason for the inductive inequity evaluated on the windings of the stator. For knowing about test consideration of wound rotor motors and data analysis you may look into the Data Interpretation Book of MCEmax.
A system of excitation in respect of a synchronous generator contains a traditional brushless exciter for offering excitation of base for power output along with a managed source of interconnected direct current with the traditional brushless exciter to allow functioning of the synchronous type generator to offer forcing excitation for allowing the function of the generator at levels of power that exceed the base power of generator’s output level.
