Mehanske izgube v univerzalnem kolektorskem motorju

POTOČNIK, ANDREJ (author), Vončina, Danijel (mentor)

Izgube predstavljajo velik problem na vseh področjih, tudi pri razvoju elektromotorjev. Vedno želimo imeti boljši izkoristek, zato je zmanjševanje izgub postala ena izmed glavnih nalog konstruktorjev električnih motorjev. V diplomskem delu so predstavljene izgube v univerzalnem komutatorskem motorju, ki je pogonski del suhe sesalne enote, s poudarkom na meritvah mehanskih izgub. Predstavljen je način meritev, razčlenitev izgub po vzroku nastanka ter njihova analiza. To predstavlja osnovo, na katero se lahko opremo pri načrtovanju motorja z višjim izkoristkom.

• Title: Mechanical losses in universal commutator motor

Abstract

Losses represent a major problem in all areas, including the development of electric motors. Customers always want to have electric motors with better efficiency, therefore reducing losses has become one of the main tasks of motor designers. This thesis presents losses in the universal commutator motor which is used for dry suction vacuum cleaners, with an emphasis on the measurement of mechanical losses. Methods for determination of mechanical losses are presented and analysed. Laboratory mesurement were provided to evaluate mechanical losses. On this basis a new design of motors with higher efficency can be made.
