3 Linear Induction Motors

Topologies, Fields, Forces, and Powers Including Edge, End, and Skin Effects

This chapter deals with flat linear induction motor (LIM) topologies, double sided and single sided, with their windings and field technical theories accounting for edge, longitudinal end, and skin effects, with the scope of providing a deep understanding of flat LIMs performance and limitations and, also, preparing analytical expressions for equivalent circuit models of LIMs to be developed and then used to investigate the dynamics and control of LIMs (Chapter 4).

3.1 Topologies of Practical Interest

As seen in Chapter 2, LIMs are counterparts of rotary induction motors. They may be obtained by “cutting” and unrolling the rotary induction ...
