Abstract

Sektor transportasi merupakan salah satu sektor utama pengguna bahan bakar fosil, meskipun ketersediaan bahan bakar fosil tersebut semakin menipis. Oleh karena itu, diperlukan solusi transportasi ramah lingkungan untuk mengurangi ketergantungan pada bahan bakar fosil, salah satunya adalah kendaraan listrik. In-wheel motor, sebagai salah satu mekanisme penggerak kendaraan listrik, menawarkan efisiensi tinggi dan pengurangan komponen transmisi daya. Namun, panas yang dihasilkan selama operasi dapat menurunkan kinerja motor jika tidak dikelola dengan baik. Penelitian ini berfokus pada perbaikan desain housing motor dengan menambahkan wafter sebagai solusi pendinginan untuk meningkatkan laju perpindahan panas. Metode eksperimen dan simulasi digunakan untuk mengevaluasi pengaruh wafter terhadap kinerja termal dan mekanis motor. Pengujian dilakukan pada in-wheel motor tipe brushless direct current (BLDC) dengan konfigurasi outer rotor, daya 1500 Watt, 48 poles, dan 54 slots. Beban diberikan menggunakan rem elektromagnetik, sementara suhu operasional dianalisis menggunakan thermal imager Fluke Ti401 Pro. Simulasi termal dilakukan menggunakan perangkat lunak Ansys Motor-CAD dengan pendekatan lumped circuit models. Hasil penelitian menunjukkan bahwa penerapan wafter secara signifikan menurunkan suhu operasional motor. Dalam kondisi tanpa beban, suhu lilitan motor dengan wafter lebih rendah 3,35°C dibandingkan tanpa wafter. Dalam kondisi diberi beban maksimum, suhu lilitan motor menurun dari 132°C menjadi 116°C. Penerapan wafter juga meningkatkan torsi sebesar 0,14%, daya sebesar 0,64%, dan efisiensi sebesar 0,6%. Temuan ini menunjukkan bahwa wafter dapat menjadi solusi efektif untuk meningkatkan kinerja termal dan efisiensi in-wheel motor.

The transportation sector is a major user of fossil fuels, although their supply is gradually decreasing. Therefore, an environmentally friendly transportation solution is needed to reduce dependence on fossil fuels, one of which is electric vehicles. In-wheel motors, as one of the driving mechanisms of electric vehicles, offer high efficiency and reduced power transmission. However, the heat generated during operation can reduce motor performance if not managed properly. This study focused on improving the design of motor housings by adding a wafter as a cooling solution to increase the heat transfer rate. Experimental and simulation methods were used to evaluate the effect of the wafter on the thermal and mechanical performance of the motor. The tests were carried out on a brushless direct current (BLDC) type in-wheel motor with an outer rotor configuration, 1500 Watt power, 48 poles, and 54 slots. The load was applied using an electromagnetic brake, and the operating temperature was analyzed using a Fluke Ti401 Pro thermal imager. Thermal simulations were conducted using the Ansys Motor-CAD software with a lumped circuit model approach. The results showed that the application of the wafter significantly reduced the operating temperature of the motor. Under no-load conditions, the winding temperature of the motor with the wafter was 3.35°C lower than that without the wafter. Under the maximum load conditions, the winding temperature of the motor decreased from 132°C to 116°C. The application of the wafter increased the torque by 0.14%, power by 0.64%, and efficiency by 0.6%. These findings indicate that the wafter effectively improves the thermal performance and efficiency of the in-wheel motor.
