The efficiency and working performance of the motor and controller system in micro-electric vehicles depends mainly on its thermal performance, which is contingent upon effective and active cooling. The working temperature of the motor and controller may be too high during operation, which properly causes motor power reduction or motor breakdowns. Therefore, it is crucial to design a good cooling channel for better cooling the integrated motor and controller system. This work proposes an integrated cooling channel of motor and controller, and the fluid-solid coupling analysis is applied for analyzing the velocity, pressure distributions of the cooling channel, and temperature distributions of motor solid components. Meanwhile, the collaborative optimization method based on the multi-island genetic algorithm (MIGA) is used to attain optimal design parameters of the integrated cooling channel of the motor and controller for obtaining a better cooling channel design with lower flow resistance and lower winding temperatures. Results show that the original cooling channel’s flow resistance and maximum winding temperature are 31.87 kPa and 120.04°C, respectively. The flow resistance and winding temperature are pretty significant. After optimization, the local vortex flow and zero velocity area in optimal cooling channel design are improved, the coolant flow velocity becomes more uniform, and the flow resistance is significantly reduced. The flow resistance and maximum winding temperature of the optimal cooling channel design are 12.5 kPa and 116.76°C, respectively, which are decreased compared with the original cooling channel structure, with a decrease of 39.4% and 2.7%, respectively. The research findings in this work can provide theoretical reference for solid components temperature evaluation of motor and give valuable data to cooling performance evaluation and optimization of integrated cooling channel for motor and controller system.

“…Turbocharger memanfaatkan gas buang untuk memutar turbin yang terkoneksi dengan kompresor, sehingga lebih banyak udara yang masuk ke dalam ruang bakar [1]. Beberapa penelitian mengenai turbocharger telah dilakukan dengan menggunakan simulasi numerik [2]- [7]. Namun, perlu dilakukan pengujian secara eksperimental untuk mengetahui efek dari turbocharger.…”

ABSTRAK Dunia otomotif di Indonesia semakin berkembang dengan pesat, jenis-jenis motor baru dari berbagai pabrikan bermunculan dengan pesat. Salah satu jenis motor yang berteknologi cukup baik adalah YAMAHA V-IXION. Tipe motor ini memiliki teknologi dasar mobil yaitu injector bahan bakar dan ECU (Electronic Controller Unit) sebagai penerapan engine mapping. Untuk menambah tenaga motor, dilakukan pemasangan turbocharger. Tujuan penelitian ini adalah meningkatkan performa mesin dengan kapasitas 150 cc dengan memanfaatkan boost dari turbocharger dengan tekanan minimal 0,3 bar. Performa mesin diukur dengan menggunakan dyno test. Setelah sistem turbocharger diaplikasikan ke mesin YAMAHA V-IXION dapat bekerja secara normal dan mampu mencapai boost hingga 0,5 bar. Hasil pengujian dyno test diperoleh: Peak daya terjadi pada 8,622 rpm dengan daya sebesar 14,7 HP, peak torsi terjadi pada 8,547 rpm dengan torsi sebesar 12,21 Nm2, dan konsumsi bahan bakar yang dipergunakan adalah 2,63 liter dengan jarak tempuh 94,6 Km. Kata kunci : V-IXION, turbocharger, dyno test ABSTRACT The automotive in Indonesia is growing rapidly, new types of motorcycle from various manufacturers have emerged rapidly. One type of motorcycle with good technology is the YAMAHA V-IXION. This type of motorcycle has basic car engine technology, namely fuel injectors and ECU (Electronic Controller Unit) as engine mapping application. To increase power, it is necessary to install a turbocharger so that motorcycle power generated can increase. The goal of this research is increase the machine performance with capacity of 150 cc by using boost from turbocharger that operate at least 0.3 bar. Machine performance was tested by using dyno test rig. After the turbocharger system is applied to the YAMAHA V-IXION engine it can work normally and is able to achieve a boost of up to 0.5 bar. The dyno test result: Peak power occurs at 8.622 rpm with a power of 14.7 HP, peak torque occurs at 8.547 rpm with torque of 12.21 Nm2, and fuel consumption used is 2.63 liters with a distance of 94.6 km. Key words: V-IXION, turbocharger, dyno test.
