... • The negative sequence current in the stator winding creates a magnetic flux wave in the air gap which rotates in opposite direction to that of rotor synchronous speed. This flux induces currents in the rotor body, wedges, retaining rings at twice the line frequency. Heating occurs in these areas ...

... If the Vref pin of the transducer is not used it could be either left unconnected or filtered according to the previous paragraph “Reference Vref”. The Vref pin has two modes Ref out and Ref In: • In the Ref out mode the 2.5 V internal precision reference is used by the transducer as the reference ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
