Abstract:
Cilj diplomske naloge je analizirati prototip trifaznega asinhronskega motorja z ulomljenim koncentričnim statorskim navitjem izvedenim z odcepom. To navitje omogoča delovanje motorja v širokem področju vrtljajev in je lahko vezano v vezavi zvezda, trikot in trikot z odcepom. Tovrsten motor je napajan s pretvornikom kateri omogoča spreminjanje napajalne frekvence in posledično spreminjanje vrtljajev. S spremembo frekvence se spreminja tudi fluks. Fluks je konstanten le od frekvence nič in vse do nazivne frekvence oziroma do slabljenja polja v katerem se zmanjšuje z višanjem frekvence. V diplomskem delu je izmerjeno delovanje prototipa motorja za vse tri omenjene vezave. Za katero frekvenčno področje je določena vezava uporabna pa je rezultat meritev opravljenih v tem diplomskem delu.

Title:
USAGE OF TAPPED STATOR WINDING FOR WIDE-SPEED RANGE INDUCTION MOTOR
Abstract:
The aim of this diploma is to analyze the prototype of a three-phase induction motor with tapped stator winding used for wide-speed range. This type of stator winding is fractional concentric which can be used as star connection, delta and delta with a tap. This motor is supplied by a converter which enables the changing of the power frequency and consequently the rotating. With the change of the rotating also the flux changes. The flux is constant only from the frequency zero until up to the nominal frequency or until the weakening of the field in which it is decreasing with the increasing of the frequency. In the diploma there are measurements for a prototype motor for all three types of bindings. Which band is what most favorable to the binding operation is analyzed in this diploma.
