| dc.description.abstract | In this thesis, a design methodology of switched reluctance motor (SRM) for an EV traction drive is presented. Based on the typical force-speed curve of an electric propulsion drive, the rated power and torque of the SRM can be determined from the desired perfom1ance specifications of the EY. Once the rated torque is obtained, the preliminary dimensions of the SRM, such as rotor bore diameter and subsequently the frame size, can be estimated. Then, other internal dimensions of the motor are predicted in accordance with the frame size using a series of empirical formulae. Due to the highly nonlinear characteristics of SRM, computer aided design tools are essential for analyzing the magnetic performance and the dynamic behaviors of the overall system. A detailed electromagnetic analysis using finite element (FE) method had been carried out to predict the magnetization and static torque characteristics of the motor. Since the operation of SRM involves a series of electrical tTansient, a Matlab/Simulink model had been developed to study the transient and steady-state dynamic performance of the SRM drive. The dynamic simulation model of the SRM was built based on the nonlinear electromagnetic characteristics obtained from FE analysis. In addition, vehicle dynamic and road load, which will transpire as effective load to the motor shaft, were incorporated into the final simulation model to study the overall performance of the EV system. In order to verify the design methodology and validate the accuracy of the simulation model, a prototype, which comprises a switched reluctance motor, power converter and system controller, had been developed. The power converter was built from IGBT chopper modules, while the system controller had been implemented on a TMS320LF2407 based evaluation module. Several tests, such as winding resistance measurement, single-pulse operation and chopping mode operation, had been conducted. The cxperimental results obtained correlated satisfactory with the theoretical predictions. Therefore, the developed simulation model can be employed as a standard designing tool for other SRM drives. | en_US |
