Determination of induction motor winding data for other nominal voltage

Diplomsko delo obravnava določitev navijalnih podatkov asinhronskega motorja za drugo nazivno napetost za šestpolni asinhronski motor. Izračunani so bili navijalni podatki za nazivno napetost 400 V in novo nazivno napetost 48 V. V obeh primerih je bilo navitje vezano v vezavo zvezda. Za napetost 48 V smo uporabili koncentrično porazdeljeno enoplastno in ulomljeno koncentrično porazdeljeno navitje, katera smo vstavili v utore statorskega paketa asinhronskega motorja in izdelali dva prototipa. Za vsako navitje so bile izračunane in izmerjene elektromagnetne in mehanske karakteristike. Z izbiro različnih navitij smo ugotavljali njihovo ustreznost pri izbiri zastavljenega cilja, to je ohraniti karakteristike motorja oziroma jih celo izboljšati.The thesis deals with winding data calculation and determination of elektromagnetic properties for rewinding a standard six-pole induction motor for other voltage. Thesis begins with winding data calculation for standard induction motor with nominal voltage 400 V and wye-connected stator winding. After this calculation procedure was repeated two times for voltage 48 V, but with different types of stator winding. The first winding was a single-layer concentric winding and the second was a fractional concentric winding. From winding results of aforementioned calculation for 48 V we made two induction motor proptotypes on which laboratory measurements in order to confirm our calculations were performed. Calculated and measured results for two prototypes offer a posibility for choosing better induction motor prototype
