Abstract

Perkembangan kendaraan listrik menuntut motor traksi yang ringkas, efisien, dan mampu menghasilkan torsi yang stabil. Penelitian ini bertujuan menganalisis Axial-Flux Permanent Magnet Synchronous Motor (AF-PMSM) bertopologi Double Stator Single Rotor (DSSR) dengan konfigurasi Halbach Array Permanent Magnet (HAPM) sebagai alternatif terhadap Inset Permanent Magnet (IPM), khususnya untuk meninjau distribusi flux, torsi, torque ripple, rugi-rugi elektromagnetik, dan efisiensi. Model motor direkonstruksi dari motor referensi 4 kW, 2000 rpm, 18 slot, dan 16 pole, kemudian dianalisis menggunakan finite element analysis melalui simulasi transient pada Ansys Maxwell. Konfigurasi HAPM dibentuk dengan satu pole pitch 22,5° yang terdiri atas magnet axial 20° dan magnet tangensial 2,5°, sehingga axial magnet fraction bernilai 0,889. Hasil validasi model IPM menunjukkan error torsi 4,79% dan error daya output 4,25%. Hasil simulasi menunjukkan bahwa HAPM meningkatkan rata-rata flux density pada air gap sebesar 4,78%, tetapi menurunkan flux linkage dari 0,0347 Wb menjadi 0,0339 Wb. Konsekuensinya, torsi rata-rata menurun dari 19,910 Nm menjadi 19,608 Nm dan daya output menurun dari 4169,968 W menjadi 4106,731 W. Meskipun demikian, torque ripple menurun dari 8,163% menjadi 4,594%, total losses menurun dari 128,052 W menjadi 124,141 W, dan efisiensi meningkat dari 97,020% menjadi 97,066%. HAPM juga memperlebar rentang kecepatan maksimum dari 2720 rpm menjadi 2770 rpm. Dengan demikian, konfigurasi HAPM pada AF-PMSM DSSR tidak memberikan peningkatan torsi rata-rata, tetapi menghasilkan trade-off berupa perbaikan kualitas torsi, dan penurunan rugi-rugi.

The development of electric vehicles requires traction motors that are compact, efficient, and capable of producing stable torque. This study aims to analyze an Axial-Flux Permanent Magnet Synchronous Motor (AF-PMSM) with a Double Stator Single Rotor (DSSR) topology using a Halbach Array Permanent Magnet (HAPM) configuration as an alternative to the Inset Permanent Magnet (IPM) configuration, particularly in terms of flux distribution, torque, torque ripple, electromagnetic losses, and efficiency. The motor model was reconstructed based on a 4 kW, 2000 rpm, 18-slot, and 16-pole reference motor, and was analyzed using finite element analysis through transient simulation in Ansys Maxwell. The HAPM configuration was formed with a 22,5° pole pitch consisting of a 20° axial magnet and a 2,5° tangential magnet, resulting in an axial magnet fraction of 0,889. The validation results of the IPM model showed a torque error of 4,79% and an output power error of 4,25%. The simulation results show that HAPM increases the average flux density in the air gap by 4,78% but reduces the flux linkage from 0,0347 Wb to 0,0339 Wb. Consequently, the average torque decreases from 19,910 Nm to 19,608 Nm, while the output power decreases from 4169,968 W to 4106,731 W. Nevertheless, the torque ripple decreases from 8,163% to 4,594%, total losses decrease from 128.052 W to 124,141 W, and efficiency increases from 97,020% to 97,066%. HAPM also extends the maximum speed range from 2720 rpm to 2770 rpm. Therefore, the HAPM configuration in the AF-PMSM DSSR does not improve the average torque but provides a trade-off in the form of improved torque quality and reduced losses.
