An Analysis of Linear Induction Motors for Propulsion and Suspension of Magnetically Levitated Vehicles

[摘要] A four-layer single-sided LIM used for propulsion and suspension of magnetically levitated vehicles is studied. The track is assumed to be made of conductors with uniaxial μ and σ. A general analysis allows us to exclude unsuitable geometries. The machine performance is given for the promising geometries. A possible way of computing the effective μ and σ for a composite track is sketched. From the analysis of an extremely simplified geometry, the conditions for the validity of the effective μ and σ concept are given. Finally, a three-dimensional correction is introduced.
