Abstract

Elektromagnetske istosmjerne kočnice pogodne su za upotrebu na dizalicama, dizalima, strojevima za obradu drveta, alatnim strojevima, vitlima, općenito na svim mjestima gdje se zahtijeva zaustavljanje mehanizama, kočenje zamašnih masa odnosno brzo zaustavljanje u slučaju prekida energije napajanja, opasnosti i sl. Uključivanje može biti izvršeno između ispravljača i magneta. Taj način uključivanja omogućava relativno kratko vrijeme isključivanja i uključivanja. Uključivanje prije ispravljača na izmjeničnoj strani uzrokuje relativno dug period otpuštanja i stezanja kočnice. Ta vremena reagiranja mogu se uspješno analizirati metodom konačnih elemenata u programskom paketu MagNet što je i cilj ovog rada.

Abstract (english)

Electromagnetic DC brakes are convenient for use in cranes, lifts, wood processing machines, tool machines, winches, generally at all places where stopping of mechanisms, fly-wheel masses or stopping due to disconnection from power supply or danger, etc. is required. The switching can be done between the rectifier and the magnet. This mode of switching provides relatively short release and engagement times. Switching before the rectifier on the AC-side causes relatively long release and engagement times. This operating times can be successfully analyzed with finite element method in software package MagNet, and this is the subject of this diploma thesis.
