Two dimensional field and finite element analyses are complementary in evaluating the performance of single-sided linear induction machines, and can be used to develop a machine design for a given drive application. Electromagnetic analysis leads to an equivalent circuit of the machine with speed and frequency dependent parameters, in which top cap geometry, core hysteresis and saturation, skin effect, eddy current reaction, and both transverse edge and longitudinal end effects can be included. Finite element analysis provis detailed information on the magnetic field distribution to aid in machine design. In this paper, we have presented a review of two analytical techniques which are complementary in evaluating the performance of a LIM, and which can be used for computer-aided-design purposes. For more complete details of the general electromagnetic equations and their development, the reader is referred to references (1-4, 8). It has been shown that a two-dimensional electromagnetic technique, with transverse edge and longitudinal end effec corrections, can be used to obtain force and terminal characteristics to sufficient accuracy for engineering design purposes. The finite element method then provides detailed information about the field distribution in the machine. Taken together, both techniques allow an optimal electromagnetic design for a LIM to be iteratively developed.
