Characteristics Analysis of Aixal Flux Permanent Magnet core-less motor

축 방향 자속 코어레스 전동기의 특성 해석

This paper deals with the design and characteristic analysis of a coreless an axial flux permanent magnet (AFPM) motor. Axial-flux permanent magnet motors prove to be the best candidate for application in electric vehicles (EVs) as direct-drive wheel motors, as in comparison with conventional motors they allow design with higher compactness, lightness and efficiency. Recently, issues regarding environment and the diversification of dependence in oil are watched with keen interest. In this theses, through the simulation of AFPM for low and high torque which has stator in the center and two rotors each side, understand its specialty, with this, make a prototype motor and design drive which can enhance the motors stability in low speed. Especially, specialty of motors torque power output will be mainly talked and based on this, possibility of application in EVs will be inspected by the theoretical study and the test.
