Abstract

Beskolektorski istosmjerni (BLDC) elektromotori često su korišteni u uređajima raznih namjena. Iako imaju mnogo prednosti u odnosu na konvencionalne istosmjerne strojeve, ipak su kompliciraniji za upravljanje. Stoga je opisan matematički model BLDC elektromotora, te je iz istog napravljena simulacija u programskom paketu Simulink. Pomoću opisanog modela i njegove simulacije moguće je testirati razne metode upravljanja, te vidjeti očekivani rezultat. Potom su projektirane, izrađene i testirane tiskane pločice koje služe za upravljanje sa četiri pojedina BLDC elektromotora. Napisan je upravljački program za reguliranje brzine vrtnje elektromotora na STM32 mikrokontroleru. Provedena su ispitivanja i dobiveni rezultati jednog kanala izrađene tiskane pločice.

Abstract (english)

Brushless direct current (BLDC) electric motors are often used in devices of various purposes. Although they have many advantages over conventional DC machines, they are still more complicated to operate. Therefore, a mathematical model of a BLDC electric motor was described and a simulation was made from it using Simulink. Using the described model and its simulation, it is possible to test various control and regulation methods and see the expected result. After that, printed circuit boards were designed, made and tested, which serve to control four individual BLDC electric motors. A driver program was written for regulating the rotational speed of an electric motor on the STM32 microcontroller. Tests were carried out and the results of one channel of the printed circuit board were obtained.
