Abstract:

The Yamamura theory of the double-sided linear induction motor (LIM) excited by a constant current source is discussed in some detail. The report begins with a derivation of thrust and airgap power using the method of vector potentials and theorem of residues. The LIM thrust computed via the theorem of residues is compared with similar results obtained using numerical integration. Both methods are seen to yield equivalent results providing the increments in the numerical integration are made sufficiently small. The finite width and length of the primary alter the LIM thrust considerably in the regions of large and small slip frequencies, respectively. The effect of finite primary dimensions on LIM thrust is discussed in detail for the examples of the Tracked Levitated Research Vehicle (TLRV) and LIM Research Vehicle (LIMRV) LIMs operating at rated speeds. A comparison of thrusts predicted by the Yamamura, Oberretl, and Elliott LIM models for the TLRV and LIMRV motors shows fair agreement in the value of thrusts predicted by the different theories.
