Abstract
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.
