Fields in permanent magnet linear synchronous machines

The determination of electromagnetic fields in permanent magnet linear synchronous machines (PMLSM's) to form the basis for the evaluation of forces and parameters of PMLSM'S (to be presented in a subsequent paper) is discussed. Analytical techniques applied to permanent magnet rotary synchronous machines are modified and adapted to PMLSM's. Fields are determined analytically in a single-sided PMLSM, and computed results by the finite-element method are compared with those obtained experimentally. A good correlation between the results obtained by the three procedures-analytical, finite-element computational, and experimental-validates the approximations used in the analysis.
