SELECTION OF ELECTRIC MOTORS FOR ELEVATOR

U radu su opisane osnove elektromehaničke pretvorbe, te navedene vrste električnih strojeva. Opisani su sastavni dijelovi i njihova podjela. Kod podjele na elektromotore detaljnije su analizirani i opisani osnovni tipovi motora (sinkroni, asinkroni i istosmjerni). Navedena je momentna karakteristika i zagrijavanje elektromotora. Opisani su elektromotorni pogoni, vrste i opterećenja, te njihovi sastavni dijelovi. Navedena su stacionarna i dinamička stanja elektromotornog pogona, upravljanje takvim pogonima kod promjene brzine vrtnje i pokretanja. Opisani su postupci pravilnog izbora motora za elektromotorne pogone i zaštita. Na temelju opisanih postupaka, izrađen je jednostavan proračun kod odabira motora za dizala.This thesis provides an overview of the foundations of electromechanical transformation, as well as the types of electrical machines. It describes the components and their classification. It provides a more detailed analysis and explanation of basic motor types (synchronous, asynchronous and DC). It features the torque characteristics and heating of electric motors. The thesis describes electric motor drives, the types and loads, as well their components. It features the stationary and dynamic states of electric motor drives, and the drive control under change of rotational speed and starting. The thesis provides an explanation of the procedural steps for the appropriate motor selection for electric motor drives and protection. Based on the described procedures, a simple calculation has been developed for the selection of motors for elevators
