Abstract
Motor BLDC (Brushless DC) merupakan salah satu jenis motor listrik yang banyak digunakan di berbagai sektor karena memiliki efisiensi tinggi, umur operasi yang panjang, dan karakteristik kecepatan terhadap torsi yang unggul. Pemilihan material inti stator merupakan parameter yang sangat penting dalam menentukan sifat magnetik, kualitas, dan kinerja motor secara keseluruhan. Penelitian ini bertujuan menganalisis kinerja motor BLDC dengan menggunakan dua jenis material inti stator yang berbeda, yaitu NV30S-120 dan M235-35A melalui pendekatan simulasi, pembuatan prototype, dan pengujian prototype. Proses penelitian meliputi studi literatur, simulasi menggunakan software Ansys Motor-CAD, pengujian rugi histeresis, pembuatan prototype, serta pengujian hasil prototype. Pengujian histeresis dilakukan dengan variasi frekuensi 50 Hz, 200 Hz, dan 500 Hz menggunakan sampel inti toroid. Prototype motor dirancang dengan spesifikasi yang identik, dengan perbedaan hanya terletak pada jenis material inti stator yang digunakan. Hasil penelitian menunjukkan bahwa material M235-35A memiliki kinerja yang lebih unggul dibandingkan dengan NV30S-120 pada seluruh parameter pengujian. Material M235-35A menghasilkan rugi histeresis yang lebih rendah (55,46 W/kg), kecepatan putaran maksimum yang lebih tinggi (11.820 RPM), torsi maksimum yang lebih besar (0,855 Nm), daya keluaran maksimum yang lebih tinggi (522 W), dan efisiensi tertinggi (88,67%). Penelitian ini membuktikan bahwa pemilihan material inti stator memberikan pengaruh yang signifikan terhadap performansi dari motor BLDC.

Brushless DC (BLDC) motors are widely used across various sectors due to their high efficiency, long operational lifespan, and superior speed-to-torque characteristics. The selection of stator core material plays a crucial role in determining the motor's magnetic properties, quality, and overall performance. This study aims to analyze the performance of BLDC motors using two different stator core materials, NV30S-120 and M235-35A, through simulation, prototype fabrication, and experimental testing. The research process includes a literature review, simulation using Ansys Motor-CAD, hysteresis loss testing, prototype construction, and performance evaluation. Hysteresis testing was conducted using toroidal core samples at varying frequencies of 50 Hz, 200 Hz, and 500 Hz. The motor prototypes were designed with identical specifications, differing only in the stator core material used. The results show that M235-35A exhibits superior performance compared to NV30S-120 in all tested parameters. M235-35A demonstrated lower hysteresis loss (55.46 W/kg), higher maximum rotational speed (11,820 RPM), greater peak torque (0.855 Nm), higher output power (522 W), and the highest efficiency (88.67%). This research confirms that the choice of stator core material has a significant influence on the efficiency and overall performance of BLDC motors.
