The Effect of Airgap Unbalance on the LIM Performance for Light Rail Road

공극 불균형이 경전철용 LIM의 특성에 미치는 영향

The LIM can be used as a transport system with wheel structure. The structural tolerance cause the airgap unbalance and that effects on the LIM performance. The effect of airgap unbalance on the motor performance such as thrust force, velocity and armature current are investigated by using Finite Element Analysis (FEA). From this numerical works, it is known that the airgap unbalance almost does not effect on the motor performance and LIM for transport system is robust to the structural tolerance.
