An electric motor is an electromagnetic machine commonly utilized across various industries and automotive products. One prevalent type of electric motor employed in electric vehicles is the Permanent Magnet Brushless DC Motor (PM-BLDC), a brushless motor employing permanent magnets. However, despite its efficiency, permanent magnet motors often experience vibrations that can disrupt their performance. This research aims to optimize the existing BLDC motor design, with a specific focus on reducing the existing cogging torque. Initially, the existing design exhibited a cogging torque level of 0.21482 Nm. The optimization process involved modifications to several key design parameters, such as air gap, magnet thickness, magnet type, and slot opening width. In previous research, only comparisons were made between stator slot designs, which proved to be less effective as significant differences were not evident in the results of the comparative analysis of BLDC motor designs. So, in this research, the Taguchi method was utilized for the optimization process due to several advantages it offers. Through an analysis of means and variance, the optimization process successfully achieved a significant reduction in cogging torque by 0.099744 and an increase in efficiency by 0.6%. The results of the optimized permanent magnet BLDC design indicated a cogging torque value of 0.115072 Nm and an efficiency of 86.64% at an operational motor speed of 1500 rpm. This research provides a substantial contribution to the development of more efficient electric motors suitable for various applications.

Kesadaran mengenai isu-isu energi dan lingkungan, industri otomotif mulai mengembangkan kendaraan listrik. Banyak negara dan produsen mobil besar telah banyak berinvestasi dalam penelitian kendaraan listrik. Di industri ada persyaratan dinamika torsi maksimum dan respon torsi kondisi tunak yang lebih baik. Ada gelombang yang lebih rendah pada fluks magnet motor dan torsi yang dihasilkan. Permanent magnet synchornous motor (PMSM) menjadi salah satu pilihan yang tepat. PMSM menggunakan rare-earth magnets yang telah diterapkan sebagai traction motor untuk kendaraan listrik karena memiliki efisiensi yang tinggi dan kepadatan daya. Penelitian ini dilakukan untuk mengetahui tingkat efisiensi yang disajikan dari berbagai jenis motor sinkron dengan spesifikasi motor yang berbeda dari slot type of coil untuk mengetahui motor sinkron mana yang lebih efisien. Sehingga penelitian ini dapat membantu para pengguna motor sinkron dalam menentukan rancangan motor sinkron yang sesuai dengan kebutuhan. Penelitian berjalan dengan menggunakan proses komputasi pada software Ansys Electronic 2018. Seluruh proses komputasi yang dilakukan menggunakan metode Finite Element Analysis (FEA) untuk menyelesaikan permasalahan medan magnet dan medan listrik secara sederhana. Tipe motor dengan kode C1 memiliki nilai efisiensi tertinggi sebesar 95,251% berdasarkan rasio dari input power dan output power dengan spesifikasi besarnya nilai kuat medan magnet sebesar 0,93409 Tesla dan laju kuat arus persatuan panjang sebesar 5,3208 Ampere per meter, serta motor ini mendapatkan nilai efisiensi yang optimal pada kecepatan konstan motor sebesar 13300 rpm dan pada 75 derajat sudut putar rotor saat bekerja.

“…In addition, beginning conditions, such as low starting current and high starting torque, are essential for fast response. Such as opinion of [2], [3], [4] to determine the electromagnetic force (EMF), it is necessary to do research on the stator winding geometry, including the stator length, stator slot geometry, the number of windings turns per slots, and the wire diameter. In addition, the EMF transfer from the stator winding to the rotor was influential in producing a high maximum torque and enhancing the spindle motor's efficiency.…”

This paper presents a strategy for maximizing the effectiveness of high-speed spindle motors in manufacturing equipment. Using the ideal design of the stator winding geometry, as calculated by the Taguchi method, we were able to increase the maximum torque and efficiency. The rotor slot geometry was optimized using a response surface to raise the starting torque and reduce the starting current. The objectives of this investigation were to come up with a strategy for designing high-speed spindle motors so that they have better performance in terms of starting torque, maximum torque, efficiency, and starting current. Spindle motor temperature rise was the focus of the thermal measurements. Finally, a working spindle motor prototype was built and tested to verify the results of the Finite element analysis (FEA). The validity of the suggested model is demonstrated by a comparison between experimental measurements and finite element findings. The total percentage of mistakes was close to 2%.
