Tesis ini membincangkan tentang merekabentuk dan menganalisis motor magnet kekal arus terus berberus (PMDC) sebagai penggerak untuk kenderaan di bawah permukaan air. Di dalam projek ini, kami menggunakan kaedah elemen terhad (FEM) beserta parameter tertentu untuk meramal prestasi motor. Perisian Opera-2D digunakan di dalam proses pelaksanaan rekabentuk model motor. Projek ini dimulakan dengan kajian terhadap kenderaan di bawah permukaan air (UV) yang mempunyai ciri-ciri dan prestasi yang tertentu. Berdasarkan kajian tersebut, tumpuan diberikan untuk merekabentuk motor yang diransang oleh 2 kutub maget kekal dan masing-masing mempunyai 12 dan 14 gigi rotor yang boleh bergerak. Dimensi motor dikira dengan menggunakan rumus matematik. Salah satu perkara yang menyumbang kepada prestasi motor ialah arah pemagnetan tetap yang terdiri daripada arah jejari dan arah selari. Kemudian, luas bukaan magnet yang terbaik perlu dikaji untuk kedua-dua jenis arah pemagnetan. Hasil-hasil simulasi yang boleh didapatkan daripada perisian Opera-2D ialah taburan medan magnet, ketumpatan medan magnet, ketumpatan fluks sela udara, penggubalan kilas dan voltan teraruh yang dihasilkan. Berpandukan kepada analisis data, projek ini akan mencadangkan motor yang terbaik sebagai penggerak untuk kenderaan di bawah permukaan air. _________________________________________________________________________________________ This paper discuss about designing and analysis of permanent magnet brushed dc motor (PMDC) for underwater vehicle propulsion system. In this project, a finite element modeling (FEM) with appropriate parameter is used to predict the motor performance. The Opera-2D software is used in the designing process to implement the motor model. The project starts with the study on underwater vehicle system that is requiring dynamic characteristics and performance. Based on that, we focus to design a motor with 12-slot armature and 14-slot armature which both being excited with 2-pole PM field. The motor dimension was calculated analytically. One of the important variables that contribute to the performance of PMDC motor is the magnetization direction of PM which is radial and parallel direction. Then, the best magnet arc spans need to find out for the both type of magnetization. The simulation results that can perform by Opera-2D are the magnetic field distribution, magnetic flux density, airgap flux density, cogging torque and EMF induced voltage. Based on the data analysis, this project will come out with the best motor model for underwater vehicle propulsion system.
