Abstract

Lõputöö raames projekteeriti Tallinna Tehnikaülikooli Elektroenergeetika ja mehhatroonika instituudi elektrimasinate laboris elektriajam proportsionaalsele sulgurventiilile. Elektriajmi ülesandeks oli avada ja sulgeda ventiili ± 2° täpsusega. Elektriajam koosneb: metall raamist, elektrimootori fiksaatorist, võlli adapterist, käigukastist, juhtimispuldist ja tagasisidest. Lõputöö käigus teostati lühike ülevaade stendi algsest seisust ja tema komponentidest. Seejärel alustati mootori valikuga, mille käigus selgitati välja mootori tüüp ja parameetrid. Analüüsi käigus valiti välja püsimagnetiga samm-mootor. Töö käigus konstrueeriti metallist konstruktsioon, mille ülesandeks on fikseerida elektrimootor vertikaalselt seisva toru külge. Konstrueeriti juhtimispult, mis koosneb: mikrokontrollerist Arduino Uno ja BL-TB6560 mootori ajamist. Projekt oli tehtud arvestades madalat eelarvet selle konstrueerimise käigus, kus võeti kasutusele kõiki võimalike kohapeal saadavaid materjale. Projekti käigus oli töötatud välja elektriajam, mis suudab avada sulgurventiili ± 2-3° täpsusega.

Abstract [en]

The aim of the following thesis, Control of the Sealing Valve with Electrical Drive, was to design an electrical drive for a proportionally sealing valve in Tallinn University of Technology, Department of Electrical Power Engineering and Mechatronics. Electrical drive’s purpose was to open and close the valve within ± 2°. The electrical drive consists of metal frame, electrical motor fixating platform, shaft adapter, gearbox, control panel and a feedback. In the course of the thesis, there was made a brief overview of the old stand and components it was made of. Afterwards, a motor that would fit the parameters of the project was chosen. It was decided that for the project a permanent magnet stepper motor would be used. For the motor of choice, a metal structure that would hold it on a vertically stacked pipe was designed. After that, a control box was designed, consisting of an Arduino Uno microcontroller, BL-TB6560 motor drive and direct current stepdown converter. Project was made while counting on a low budget. Because of that, all the available materials that were available on the spot were used. As a result of the project, an electrical drive was developed that could open the valve within ± 2-3°.
