STUDY OF REACTION FORCES IN A SINGLE SIDED LINEAR INDUCTION MOTOR (SLIM)

SLIM reaction forces were measured on a laboratory model having aluminum and aluminum-iron secondaries and the results were correlated with the theoretical forces derived for different idealized SLIM models. The first part of the report discusses wave solutions for single- and multi-region secondaries utilizing the Maxwell Stress Tensor to evaluate the thrust and normal forces. The second part of the report presents data of thrust and normal forces as a function of the stator excitation frequency for different SLIM configurations. The results are helpful both in providing an insight into improved SLIM design and in defining those applications in which the SLIM possesses certain advantages over its double-sided counterpart, as for example, in the application of the LIM to levitated high-speed vehicles.
