20.500.12556/RUL-94906 Pregled zmožnosti modernega frekvenčnega pretvornika Overview of the capabilities of a modern frequency converter Asinhronski elektromotorji so največkrat uporabljeni eletromotorji. Njihova največja slabost je, da jim ne moremo enostavno spreminjati vrtilne hitrosti. Z uporabo frekvenčega pretvornika je problem upravljanja vrtilne hitrosti enostavno odpravljen. V diplomski nalogi so predstavljene nekatere zmožnosti modernega frekvenčnega pretvornika. Ker pa imajo danes ti frekvenčniki veliko funkcij, se jih najlažje krmili kar preko računalniške programske opreme. V našem primeru je bil to programski paket CX-drive, preko katerega krmilimo elektromotor. Uporabimo pa lahko tudi že v frekvenčnik vgrajen PID krmilnik. Asynchronous motors are the most commonly used electric motors. Their biggest disadvantage is that we can not change their rotational speed easily. If using a frequency converter, the problem of rotational speed control is simply solved. The thesis presents some of the capabilities of a modern frequency converter. Since these frequency converters have many functions today, they are best controlled through computer software. In our case, the CX-drive software package was used to control the electric motor. Our frequency converter also makes it possible to use PID controller integrated in the frequency converter. frekvenčni pretvorniki elektromotorji PID krmilniki merilni sistemi vrtilno magnetno polje moment frequency converters electric motors PID controllers measuring systems rotating magnetic field torque true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-11 13:30:11 2017-09-11 13:30:13 2023-11-10 13:40:24 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 199968 893.pdf 893.pdf 1 2390A210AEE2ECE694A857C237E9764E ac3d837e600197ba8883fbf6fcbff07cbafea89a1827953ae8643cf53c7c5949 a16f4a94-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/35046893-cc01-4ac0-8127-589e7e380ec8 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=103385 Fakulteta za strojništvo 0 0 0
