Abstract

Gokart listrik Nogogeni ITS Team dituntut untuk memiliki akselerasi dan kecepatan puncak yang kompetitif pada kategori Speed Race dengan batasan regulasi tegangan baterai 72 Volt dan maksimum discharge 60 Ampere. Penelitian ini bertujuan untuk merancang, menyimulasikan, dan manufaktur perubahan lilitan motor Brushless Direct Current (BLDC) guna mencapai daya puncak 5 kW, target kecepatan putar 4000 RPM, dan efisiensi di atas 85%. Metode yang digunakan meliputi simulasi dinamika traksi kendaraan dengan Simulink MATLAB dan pemodelan elektromagnetik menggunakan perangkat lunak Ansys Electronics dengan fitur didalamnya ada Ansys RMxprt. Pengembangan berfokus perubahan pada stator dilakukan dengan mereduksi jumlah lilitan menjadi 3 turns dan menggunakan 54 untai kawat tembaga paralel berdiameter 0,64 mm untuk memaksimalkan kapasitas hantar arus. Pengujian performa dieksekusi menggunakan kontroler merek flipsky 75350 dengan softwarenya VESC berbasis Field Oriented Control dengan variasi pengujian pembebanan langsung yakni batas arus transien (Motor Current Max) sebesar 200A, 250A, dan 300A. Hasil pengujian menunjukkan kecepatan putar tanpa beban mencapai 3448 RPM. Pada pengujian pembebanan langsung, variasi arus 300A menghasilkan performa paling superior dengan lonjakan torsi puncak sebesar 46,7 Nm, daya input transien 5024 Watt, dan kecepatan maksimum 75 km/jam. Tingkat efisiensi konversi daya kelistrikan menuju mekanis terbukti stabil pada fase kecepatan konstan di angka 92,67%. Pengembangan ini disimpulkan bahwa perubahan reduksi jumlah lilitan dapat meningkat sebesar 10,04 % dari sebelum dilakukan pengembangan. Meningkatkan diameter kawat dan banyaknya untai (strand parallel) mampu meningkatkan kuat hantar arus continue sebesar 173,34 A sehingga lilitan aman dari panas ketika dilakukan pengujian pembebanan langsung.

The Nogogeni ITS Team electric go-kart is required to have competitive acceleration and top speed in the Speed Race category, with regulatory constraints of a 72Volt battery voltage and a maximum discharge of 60 Amperes. This research aims to design, simulate, and manufacture a stator winding modification for a Brushless Direct Current (BLDC) motor to achieve a peak power of 5 kW, a target rotational speed of 4000 RPM, and an efficiency above 85%. The methods used include vehicle traction dynamics simulation using MATLAB Simulink and electromagnetic modeling using Ansys Electronics software, specifically the Ansys RMxprt feature. The development focuses on stator modifications by reducing the number of windings to 3 turns and using 54 parallel copper wire strands with a diameter of 0.64 mm to maximize the current-carrying capacity. Performance testing was executed using a Flipsky 75350 controller with VESC software based on Field Oriented Control, employing direct load testing variations with transient current limits (Motor Current Max) of 200A, 250A, and 300A. The test results showed a no-load rotational speed reaching 3448 RPM. In the direct load testing, the 300A current variation produced the most superior performance with a peak torque surge of 46.7 Nm, a transient input power of 5024 Watts, and a maximum speed of 75 km/h. The efficiency level of electrical to mechanical power conversion proved stable during the constant speed phase at 92.67%. This development concluded that the reduction in the number of turns resulted in a 10.04% increase compared to before the modification. Increasing the wire diameter and the number of parallel strands was able to minimize the torque drop of the BLDC motor and increase the continuous current carrying capacity, ensuring the windings remained safe from overheating during direct load testing.
