Abstract

The efficiency of control systems in permanent magnet synchronous motors (PMSM) is crucial, especially for applications in physiotherapy robots. Previous studies have demonstrated that an open-loop field-oriented control (FOC) driver using BTS7960 outperforms the commonly used electronic speed controller (ESC). This research addresses the challenge of further improving efficiency by employing a closed-loop FOC driver with the BTS7960. The research methodology involves two main stages. First, a PSIM software simulation of a closed-loop FOC using a proportional integral (PI) controller is conducted. The aim is to determine the P and I parameters that result in the smallest settling time, steady-state error, and overshoot in controlling the PMSM motor's rotation per minute (RPM). The second stage involves hardware implementation with the BTS7960, where the PMSM motor RPM is compared under various loads ranging from 10-gram to 60 gram. RPM results from both open-loop and closed-loop configurations are compared. The results show that the closed-loop FOC driver has improved system transient response compared to the previous open-loop FOC driver, notably reducing the settling time from 2.24 seconds to 1.45 seconds for a 60 gram load. Therefore, this research concludes that a closed-loop configuration with well-tuned PI parameters can deliver better performance compared to open-loop methods, as clearly demonstrated.

Abstract

The main challenge faced by many countries is the limited fossil fuels due to the dwindling supply of fuel oil. Indonesia itself faces serious problems in providing sufficient fuel, even having to import from other countries, which can have a negative impact on the energy needs of its growing population. To overcome this problem, the use of renewable energy sources is a very relevant alternative solution. Renewable energy needs to be expanded, especially with the increasing price of fuel. One of the most prominent examples is the use of electrical energy. Electric motors have become a major focus in the development of electric vehicle technology and various industrial applications. One type of electric motor that is increasingly popular is the BLDC motor. The use of inefficient BLDC motors can cause significant energy waste, one of the factors that affects the design of BLDC motors is the winding configuration. This study aims to improve the performance of the 2kW electric motor dynamo to meet government regulations on electric vehicle conversion standards. BLDC motors are vital components in various industrial and transportation applications due to their high efficiency. This study focuses on the analysis of the BLDC motor winding configuration to achieve optimal energy efficiency by developing existing products. This study conducted simulations using Ansys Motor-CAD and performance tests were carried out under various load conditions. The results of the study showed an increase in efficiency from 82% to 87% and motor torque through variations in the winding configuration was obtained from 42 Nm to 54 Nm according to the results of the traction analysis of 44 Nm. This is expected to support the development of electric vehicles such as electric scooters.

Abstract

This paper presents an analysis of the design method of a BLDC (Brushless DC) motor with a wheel-hub structure. This study examines how variations in winding configuration affect motor performance. A 650W wheel-hub BLDC motor will be tested by modifying its stator design, including variations in the number of wires, the number of parallel circuits, and the diameter of its conductor. The test focuses on the effect of these changes on the torque, efficiency, output power and rotational speed of the motor.The test was carried out using standard sized wires. The results show that appropriate winding arrangements can increase motor torque and speed. When the parallel circuit configuration is used, the motor efficiency increases and the wire diameter is optimized. Based on the design implementation carried out, the 650W hub-type BLDC motor tested was able to achieve a maximum power of 956W, a maximum speed of 477 rpm, and a maximum torque of 41 Nm. In addition, the highest efficiency achieved was 86% at a torque of 31.8 Nm, a speed of 239 rpm, and a power of 956W.The results of this study emphasize the importance of proper winding configuration in optimizing motor performance. This winding configuration selection procedure is expected to be a reference in the manufacture of wheel-hub BLDC motors.

Abstract

Desa Songo adalah sebuah desa di Surabaya yang menggalakkan aktifitas urban farming untuk ketahanan pangan lokal. Tidak hanya itu, kegiatan urban farming juga dapat menjadi sumber pendapatan sebuah desa karena harga komoditas hidroponik yang cukup bersaing dibandingkan dengan komoditas non-hidroponik. Pada kegiatan ini, tim pengabdian melakukan diseminasi unit hidroponik berbasis tenaga surya yang dapat beroperasi tanpa menggunakan tenaga dari PLN. Diseminasi hidroponik berbasis tenaga surya ini diharapkan dapat berjalan secara berkelanjutan sehingga dapat memenuhi kebutuhan pangan desa juga dapat menjadi sumber pendapatan desa. Hidroponik yang didiseminasikan memiliki 300 lubang tanam, sumber tenaga baterai 12V 200Ah dan panel surya 900Wp dengan dukungan inverter 1kw. Terdapat pompa air hidroponik yang dapat dinyala matikan menggunakan saklar manual. Peramalan profit sederhana dilakukan untuk melihat potensi dari hidroponik yang didiseminasikan. Hasilnya menunjukkan bahwa hidroponik yang didiseminasikan dapat menghasilkan keuntungan akhir Rp 19.232.727 sehingga dalam waktu 13 bulan akan terjadi balik modal dari investasi perangkat hidroponik yang telah dilakukan sebelumnya. Hasil peramalan ini juga terpengaruh dengan beberapa asumsi pesimis seperti maksimal hasil panen bagus adalah 90% dan hasil panen terendah yang terjual hanya 50%. Dengan demikian sumbangsih nyata perangkat hidroponik terhadap ekonomi Desa Songo diprediksi akan terjadi pada bulan ke-13 setelah balik modal terjadi.

Abstract

Good air quality is vital for human health, one important factor being the range of carbon dioxide levels that can be tolerated by the respiratory system. In this study, the type of gas sensor used was an electrochemical sensor, which has a higher level of selectivity than semiconductor sensors, resulting in more accurate carbon dioxide gas measurements and easier air quality classification. For carbon dioxide readings, this study used an MG-811 gas sensor. Carbon dioxide readings were also compared with a commercial gas measuring device, namely BOSEAN. In addition, the fuzzy inference system method was used to classify air quality into three levels of conditions, namely low, normal, and alert. Based on the data analysis results, the mean absolute percentage error (MAPE) value for the comparison of carbon dioxide gas readings between the MG-811 gas sensor and BOSEAN is 2.23%. Overall, the fuzzy inference system that has been developed works well and can be used to classify air quality automatically.
