Application of asynchronous motors in the personnel's electric lifts

Abstract

Moderni načini gradnje i moderni načini izvođenja tehnologije u uskoj vezi su s primjenom dizala. Naime upravo su dizala danas jedna od neizostavnih stavki svake zgrade, nebodera, tvornice pa čak i naftnih platformi. Dizala su ta koja su omogućila lakši te brži prijevoz putnika, odnosno osoblja, ali i tereta te na taj način omogućila lakšu svakodnevnicu, ali i poslovanje. Današnji osnovni tip dizala je dizalo koje se pokreće putem elektromotora i to najviše trofazne izvedbe. Upravo ovaj tip elektromotora ima potrebnu snagu te druge parametre kako bi omogućio pokretanje dizala. Za dizala su značajni asinkroni motori koji predstavljaju temelj ovog rada. Riječ je o motorima koji se koriste ne samo u dizalima nego i u postrojenjima i tvornicama i to zahvaljujući svojoj osnovnoj prednosti, a to je indukcijski način prijenosa električne energije djelovanjem okretnog magnetskog polja. Cilj rada je prikazati djelovanje asinkronih motora u dizalima namijenjenim za osoblje te na taj način istaknuti prednosti navedenog.Modern ways of building and modern ways of implementing technology are closely related to the use of elevators. Namely, they have just lifted one of the indispensable items of every building, skyscrapers, factories and even petroleum platforms today. Elevators were the ones that made it easier and faster to transport passengers, staff and cargo, thus enabling easier everyday life as well as business. Today's basic type of elevator is an elevator powered by an electric motor and this is the most three-stage performance. This type of electric motor has the required power and other parameters to enable the elevator to be started. For lifts are important asynchronous motors that form the basis of this work. These are engines that are used not only in lifts but also in plants and factories, thanks to its basic advantage, which is an induction of the transmission of electric energy by the action of a rotating magnetic field. The aim of this paper is to demonstrate the performance of the asynchronous motors in the booths intended for the staff, thus highlighting the advantages of the mentioned
