Krmiljenje brezkrtačnih motorjev

diplomsko delo

Abstract

Brezkrtačni enosmerni motorji pokrivajo širok spekter naprav, saj dosegajo visoke hitrosti, navor in dolgo življenjsko dobo. Brezsenzorski BLDC motorji vsebujejo vse to, poleg tega pa so prostorsko optimalnejši in cenejši. Konec koncev, zakaj bi uporabili mehanske naprave, da preklapljajo tokove statorskega navitja, če to lahko storimo z elektronskim vezjem. Zato se moje diplomsko delo osredotoča na implementiranje programske kode na že izdelano elektronsko vezje, ki skupaj tvorita produkt za industrijo. Programsko kodo sem izdelal s pomočjo orodij, ki jih za te vrste motorjev ponuja podjetje STMicroelectronics. Ključni problemi so bili vzpostaviti povezavo z vezjem, ustrezna nastavitev mikrokontrolerja, nastaviti tokovno zaščito in določiti obratovalni cikel za upravljanje tranzistorjev v šest-koračnem načinu. V programski kodi je bilo potrebno nastaviti še vse parametre za motor, ki sem ga uporabljal. Meritve sem izvedel v laboratoriju podjetja Domel in ugotovil, da je motor ustrezno delujoč in se lahko uporablja za razne baterijsko gnane aplikacije.

Secondary title:	Controlling brushless motors
Secondary abstract:	Brushless DC motors cover a wide range of applications, delivering high speeds, torque and long lifetime. Sensorless BLDC motors include all of that and are also more space-optimised and cheaper. After all, why would we use mechanical devices to switch stator winding currents when we can do it with an electronic circuit. Therefore my thesis focuses on the implementation of software code on a pre-built electronic circuit, which together form a product for industry. The software code was made using STM programs which are used for this type of motors. Key problems were establishing connection with my electronic circuit, properly setting up the microcontroller, overcurrent protection and defining the duty cycle for transistors in six-step commutation. I also had to set all the parameters for the motor I was using. I took the measurements in Domel's laboratory and found out that it is a properly functioning motor and could be used for various battery-powered applications.
