Abstract
The characteristics in the linear induction motor (LIM) mode of new wireless energy transmission device are cleared analytically. The apparatus operates as two types of LIM with propulsion force or a linear transformer without thrust. One type of the LIM is a secondary current controlled wound type of LIM with primary winding on ground and the other is the LIM with reaction plate on ground. The paper shows the characteristics of the wound type of LIM in power running and has the onboard power transmission function even in the power running. The two-dimensional finite element method (FEM) is used for the analysis. As a result, it is cleared that the model designed for urban transit has high efficiency and high input power factor respectively more than 0.9 for the optimal control.
