Electric Brake : Adjustable Torque for a Wind Turbine Model (English)
Abstract [sv]

Arbetet gick ut på att konstruera och designa ett kretskort som, med hjälp av enmotor, ska fungera som en elektrisk broms för en miniatyrmodell av ett vindkraftverksom används i grundutbildning vid Linköpings universitet. Anledningen till att dettagörs är att man vill underlätta för laboranten genom att göra laborationen mer repeterbar och mindre känslig vid justeringar. Detta medför att laborationen ska varamer pedagogisk och lärorik. Till en början togs det fram hur man kan använda enmotor som broms till vindkraftsmodellen, men även hur användaren skulle kunnajustera det bromsande momentet med hjälp av olika inputs. Ytterligare funktionersom kunde vara nödvändiga uppkom under projektet, såsom att även kunna användamotorn som en drivande kraft till vindkraftsmodellen, vilket ledde till hur slutkretsens design blev till. Arbetet påbörjades med kravspecifikation, avgränsningar samtförstudie. Därefter konstruerades och designades kretskortet. Tester utfördes på denfärdiga produkten för att se om den uppfyller de krav som har formulerats. Trots vissosäkerhet när det gäller resultaten i de tester som genomförts, ändras inte det generella beteendet för hur laborationen är tänkt. Produkten anses uppfylla sin funktionmen att det finns förbättringar.

Abstract [en]

The project involved designing and developing a circuit board that, with the help ofa motor, functions as an electric brake for a miniature model of a wind turbine. Thereason for this is to simplify the work for the user by making the experiment morerepeatable and less sensitive to adjustments. This ensures that the experiment is moreeducational and instructive. In the beginning, it was looked into how a motor couldbe used as a brake for the wind turbine model, as well as how the user could adjustthe braking torque using various inputs. Additional features that could be necessaryarose during the project, such as the ability to also use the motor as a driving force forthe wind turbine model, which led to the design of the final circuit. The work beganwith a requirements specification, boundaries, and a preliminary study. Afterwards,the circuit board was designed and developed. Tests were conducted on the finishedproduct to determine whether it met the formulated requirements. Despite someuncertainty regarding the results of the tests carried out, the overall behavior ofthe experiment remains unchanged. The product is considered to fulfill its intendedfunction, although improvements are possible.
