Abstract

Penelitian ini dimulai dengan mengidentifikasi permasalahan utama pada sistem propulsi kendaraan listrik, yaitu keterbatasan performa motor Surface-Mounted Permanent Magnet Synchronous Motor (SMPMSM) saat menggunakan controller standar. Untuk menjawab tantangan ini, digunakan pendekatan yang sistematis melalui studi literatur mendalam mengenai prinsip kerja SMPMSM, metode kontrol canggih Field-Oriented Control (FOC), dan strategi peningkatan kecepatan melalui teknik Field Weakening. Dimensi fisik motor diukur secara teliti untuk membuat model digital akurat menggunakan perangkat lunak MotorXP-PM. Simulasi Magnetostatic dan DQ Analysis dilakukan untuk menghasilkan peta performa optimal serta menentukan nilai arus Id dan Iq ideal pada berbagai kombinasi putaran (RPM) dan bukaan throttle. Data optimal tersebut disusun ke dalam Lookup Table (LUT) yang komprehensif. LUT kemudian diimplementasikan ke firmware controller kustom berbasis mikrokontroler STM32 melalui STM32CubeIDE dan diunggah menggunakan STM32 ST-Link Utility. Kalibrasi dan input nilai LUT dilakukan dengan presisi melalui software Dynamits MCU yang dikembangkan sendiri untuk mempermudah konfigurasi parameter motor dan penerapan FOC. Tahap akhir berupa pengujian eksperimental menggunakan chassis dynamometer menunjukkan peningkatan performa yang signifikan: daya puncak meningkat 2,43 kali (dari 2,04 kW menjadi 4,96 kW), torsi puncak naik 1,16 kali (dari 116,29 Nm menjadi 134,73 Nm), dan kecepatan maksimum bertambah 1,56 kali. Meski daya hasil eksperimen 38% lebih rendah dari simulasi karena kerugian dunia nyata, tren hasil keduanya menunjukkan korelasi kuat, sehingga memvalidasi model yang digunakan. Dari hasil ini dapat disimpulkan bahwa arus Iq merupakan penyumbang utama torsi, sedangkan injeksi arus Id negatif efektif memperluas rentang kecepatan melalui strategi Field Weakening. Dengan efisiensi sistem mencapai 96% untuk controller dan 92% untuk motor, penelitian ini membuktikan bahwa implementasi FOC berbasis LUT hasil optimasi simulasi sangat efektif untuk memaksimalkan performa motor SMPMSM, serta mampu menghasilkan sistem penggerak yang lebih unggul dari standar dan kompetitif terhadap produk komersial di pasaran.

This research began by identifying a fundamental problem in electric vehicle propulsion systems: the limited performance of Surface-Mounted Permanent Magnet Synchronous Motors (SMPMSM) when using standard controllers. To address this challenge, a systematic approach was adopted, starting with an in-depth literature review on SMPMSM operating principles, advanced Field-Oriented Control (FOC) techniques, and speed enhancement strategies using Field Weakening methods. The motor’s physical dimensions were carefully measured to create a precise digital model using MotorXP-PM software. Magnetostatic and DQ Analysis simulations were then performed to generate optimal performance maps and determine ideal d-axis (Id) and q-axis (Iq) current values for various RPM and throttle conditions. These optimal values were compiled into a comprehensive Lookup Table (LUT). The LUT was implemented into a custom controller firmware based on the STM32 microcontroller, using STM32CubeIDE and uploaded via STM32 ST-Link Utility. Precise calibration and LUT input were conducted through the custom-developed Dynamits MCU software, enabling fine-tuned motor parameter configuration and FOC application. In the final stage, experimental validation using a chassis dynamometer demonstrated significant performance improvements: peak power increased by 2.43 times (from 2.04 kW to 4.96 kW), peak torque by 1.16 times (from 116.29 Nm to 134.73 Nm), and maximum speed by 1.56 times. Although experimental power was 38% lower than simulation predictions due to real-world losses, the strong trend correlation between both validated the accuracy of the developed model. The findings confirm that Iq current is the primary contributor to torque, while negative Id current injection is crucial for extending speed range via Field Weakening. With system efficiency reaching 96% for the controller and 92% for the motor, this study quantitatively proves that simulation-optimised FOC implementation using LUT is highly effective in unlocking the full potential of SMPMSM, resulting in a drive system that outperforms standard controllers and remains competitive with commercial solutions.
