20.500.12556/DKUM-15144 IZKORISTEK ENOFAZNEGA ASINHRONSKEGA MOTORJA ZA POGON KOMPRESORJA EFFICENCY OF SINGLE-PHASE INDUCTION MOTOR DRIVE FOR COMPRESSOR APPLICATION Cilj diplomske naloge je izmeriti in analizirati karakteristike enofaznega asinhronskega motorja pri napajanju 220V/50Hz. Poseben poudarek pri meritvah (brez mehanskih izgub rotorja) je namenjen pravilni določitvi izkoristka enofaznega motorja, za kar je v diplomskem delu predstavljena posebna metoda določitve izkoristka. Analiziranih in izmerjenih je bilo več prototipov enofaznih asinhronskih motorjev za pogon kompresorske enote v hladilniku. V okviru diplomske naloge je bil cilj izbrati tisti prototip, ki dosega najboljši izkoristek in vrednosti , ki so približno enake 1. To smo poskušali narediti tako, da smo spreminjali materialne in fizične lastnosti motorja. Pri posameznih prototipih smo spreminjali velikost kondenzatorja, upora ter kvaliteto uporabljene statorske in rotorske pločevine in navitje pomožne faze. Posledično so se spremenile izgube v železu in tudi karakteristike vrtilnega momenta motorjev. Celotni postopki meritev in izračunov za prototipe motorjev so prikazani v diplomskem delu. Celotno delo in meritve smo opravili v Laboratoriju za električne stroje (LABES) na Fakulteti za elektrotehniko, računalništvo in informatiko Univerze v Mariboru. The goal of the diploma work is to measure and analyse the characteristics of a single-phase asynhronous motor charging 220V/50Hz. Special stress on measuring (without mechanical loss of the rotor) is made on the correct determination of the single-phase motor's use, therefore a special method of its determination is introduced in the diploma letter. Several prototypes of single-phase motors for the drive of the compressor unit in the refrigerator were analysed and measured. In the frame of the diploma work the goal was to choose the prototype which reaches the best use and the value that is approximately 1. We tried to achieve this by watching the size of the condenser and the physical characteristics of the motor. With single prototypes we watched the condenser size, strength and quality of the stator and rotor sheet and coil of the assisting phase. As consequence the loss in the iron and also the characteristics of the rotation moment of the motor changed. The complete procedure of measurements and the calculation for the motor prototypes are shown in the diploma paper. The complete work and measurements were made in the Laboratory for electrical machines (LABES) on the Faculty for Electronics, Computer Science and Information Science at the University of Maribor. enofazni asinhronski motor karakteristika vrtilnega momenta izgube moči izkoristek single-phase asynhronous motor momentum characteristics loss of strength use true true false [D.
