Theory and design of linear induction motors with steel reaction plates

The theory of linear induction motors (LIMs) on steel reaction plates for low-speed applications is presented. The difference in operation of LIMs on steel and aluminium (nonferromagnetic) reaction plates are highlighted using the derived goodness factor for LIMs on steel reaction plates. The specific design parameters for LIMs operating with steel reaction plates are derived. Comparison between the measured `dynamic test?? results and predicted results show the validity of the theory for low-speed applications.
