Outer rotor type in-wheel Blushless DC Motor(BLDCM) for three-wheeled electric vehicle is researched. In-wheel system is to drive the electric vehicle without mechanical transmission, shaft, differential gears or other mechanical system. The motor is designed considering the performance requirements and drive modes of the vehicle. The determined dimensions as well as the slot and rotor pole are simulated by magnetic and thermal finite element analysis and ansys workbench to analyze the performance and heating of the motor. In order to verify the performance characteristics of the proposed motor, the experiment tests are executed and satisfy well the requirements.

본 연구에서는 전기이륜차의 1회충전주행거리를 알아보기 위해 도로 주행시험과 차대동력계(Chassis Dynamometer) 주행시험을 하였다. 도로주행시험은 대전시(Daejeon Metropolitan City)의 도로 중 대표적인 3가지 루트에서 주행시험을 하였다. 차대동력계를 이용한 CVS-40모드 주행시험의 경우 도로 부하조건을 다양하게 설정하여 CVS-40 모드주행을 실시하였다. 본 연구를 통하여 도로에서의 전기이륜차의 1회 충전주행거리(Per-Charge Range Testing)를 확인하고, 차대동력계 도로부하 설정방법에 따른 주행거리 및 에너지소비효율을 측정하였다. 이를 통해 실도로 주행시험과 차대동력계 주행시험을 비교하여, 차대동력계 실험에서도 전기이륜차 1회충전주행거리시험이 실도로에서의 주행조건과 근접한 결과를 갖는 도로부하 설정에 대해 연구하였다.

In this research, tricycle vehicle simulation based on multi-body environment has been introduced. Mathematical model of tricycle vehicle was developed. In this research the left and right wheel speed are calculated based on the rear steering angle and velocity. The kinematic model for the three - wheel drive system was completed and the results were analyzed using the actual vehicle drawings. Through simulink vehicle performance on linear and rotation movement were simulated. Using the mathematical model the control system can be applied directly to the tricycle vehicle. The simulation result shows that the proposed vehicle model is successfully represent the movement characteristics of the real vehicle. This model assists the vehicle developer to create the controller and understand the vehicle during the development process.
