ANALYSIS OF ADDITION THE NUMBER OF HALF CIRCLE TYPE SLOT ON PERFORMANCE CHARACTERISTICS OF DISC CONDUCTOR EDDY CURRENT BRAKE

Brake is a vital component of a vehicle, particularly for motor vehicles. One of the braking used the principle of Eddy Current Brake by utilizing electromagnetic. Eddy Current Brake is a braking technology without direct contact by utilizing eddy currents. Eddy Current Brake performance can be influenced by several factors, one of them is the surface shape of the disc conductor. Using finite element simulation, this research examines the impact of increasing the number of slot half-circles on the performance of the Eddy Current Brake with the number of slot changes. Variations number of slots that used are 6, 8, 10, and 12 slots. The result of this study obtained the best braking torque value in the variation with the number of 10 slots at a rotational speed of 450 rpm with a 15,930 Nm torque value. The addition slots of the number of half-circle types have a less significant effect on the torque from the simulation

Axial Unipolar Eddy Current Brake Performance Characteristics Against Heat Increase in Rotor

The development of transportation technology in the automotive sector such as electric vehicles is increasingly advanced. One technology that is needed quite a lot is the development of supporting technology for electric vehicle braking. The use of regenerative braking on light electric vehicles such as 2-wheeled vehicles is not efficient because of its low weight. The use of Eddy Current Brake (ECB) can be a solution for braking support needs. This is because the ECB is a braking system that has the advantage of a lightweight design but still relies on the frictionless principle. However, in addition to its advantages, the eddy current brake is still in the early stages of its research with efficiency that still needs to be developed. In the discussion of the ECB, heat generation is one of the interesting topics to be discussed. Specifically, the study of the characteristics of the unipolar ECB axial performance on heat generation events has not yet been discussed. So this article aims to discuss these events with a simulation process and simple mathematical calculations. Design optimization is done to get the best value. As a result, the use of eddy current brakes with conductor disks using slots, can improve the performance of the ECB on the torque side and cooling side. Thus, this article is a good contribution to the sustainability of ECB research in both the general and automotive fields

Development of Tourism Villages Through Digitalization and Micro/Small/Medium Enterprises (MSMEs) Potential in Kepyar Village, Wonogiri

Kepyar Village has great potential to be developed as a tourist village through empowering tourism potential and MSMEs. The service activities carried out aim to increase the knowledge and skills of the Kepyar Village community regarding the implementation of digitalization in developing tourist villages. Service activities consist of developing digitalization of MSMEs and village tourism potential through websites. Digitalization of MSMEs is carried out through digital marketing outreach, assistance in creating a Google My Business account, as well as digital marketing assistance through the TikTok Shop application. The development of a tourist village website is carried out by observing natural potential and MSMEs, creating a website, and socializing the results of the website. Follow-up efforts that can be taken include handing over the website to the village and providing assistance to manage it independently, providing assistance to the community to develop and manage tourism and MSMEs digitally, as well as evaluating the performance and success of the digitalization program that has been attempted to be carried out. development of services and marketing methods that suit people's preferences

Bibliometric Analysis of Heat Generation in Eddy Current Brakes

The eddy current brake (ECB) is a braking technology that continues to be developed. The use of the ECB has excellent potential to be applied to vehicles. Various studies have proposed the design, characteristics, and advantages of each. However, further analysis is needed to assess the performance of the ECB and what factors affect the performance. However, no studies have been found that discuss eddy current brakes using bibliometric analysis. Bibliometric analysis is a method used for mapping and knowledge of existing gaps in a particular topic. This article aims to provide a complete discussion with bibliometric statistical methods that have never been presented before in the field of eddy current brakes, especially the phenomenon of heat generation. In addition, the prediction of research gaps in this field can be identified as the initial results of further research. The analysis was carried out using VOSviewer and Biblioshiny integrated through the RStudio tool. The data are obtained through the Scopus database, which is then exported in CSV form. Obtaining the data depends on the keywords used. In this case, the obtained document is filtered with the features provided by Scopus. From the analysis conducted, it was found that the topic related to heat in eddy current brakes is still a recent discussion. Discussions on the heat increase in the ECB are still limited and require mapping and analysis of what parts still need development. The phenomenon of heat generation is one novelty that allows it to be researched. One example from the scientific data obtained is that there are 207 documents in the form of articles and conference papers with a total of 533 authors

Analysis of Heat Generation on Unipolar Axial Eddy Current Brake Disc and Its Effect on Braking Performance

The braking system is one of the most important components of a vehicle. In general, the brakes will generate heat due to the braking process. The heat generated must be released into the environment to maintain braking performance at optimal conditions. In extreme conditions, braking will fail. The braking system can be developed as a braking support system is a non-contact braking system. One form of the non-contact braking system is the eddy current brake (ECB). ECB is an electric braking system with the principle of eddy current. In the ECB, overheating will result in decreased performance. The approach that can be taken to determine braking performance during heat generation is the modeling process using FEM. This study uses FEM to analyze the heat generated during braking. In addition to using FEM, research was carried out using experiments as a comparison. Analysis of heat generation in braking is needed to determine whether braking with ECB can be a backup and its potential as a substitute for friction brakes. The results show that the ECB heat generation event that affects the temperature rise reduces the braking torque performance. Research indicates that when overheating occurs, braking performance will decrease by up to 10% when the disk surface temperature rises more than 20 °C. It shows the importance of managing heat that occurs in the ECB
