Modeling of a linear solenoidal actuator using finite element method

U ovome radu opisani su aktuatori i njihova primjena u sustavu automatske regulacije te princip rada. Posebno je opisan solenoidni aktuator. Budući da se princip rada zasniva na elektromagnetizmu, pobliže je objašnjen rad elektromagneta, odnosno djelovanje magnetskog polja na vodič kroz koji teče struja te relacije vezane za djelovanje, kao i klasifikacija magneta. Opisana je metoda konačnih elemenata te je u MagNet programu analiziran rad linearnog solenoidnog E-400 aktuatora u dva stabilna stanja, čiji su rezultati prikazani u ovome završnom radu.This paper describes actuators and their application in automatic control system and operation. The solenoid actuator is specifically described. Since the principle of operation is based on electromagnetism, the work of the electromagnet is explained in more detail, ie the action of the magnetic field on the conductor through which the current flows and the relations related to the action, as well as the classification of magnets. The finite element method is described and the operation of a linear solenoid E-400 actuator in two stable states is analyzed in the MagNet program, the results of which are presented in this final paper
