The structure and operation of a four-legged linear parametric motor include such excellent features as a very simple construction and negligible operating maintenance. We calculated the performance characteristics of such linear motors numerically, using a two-dimensional static field analysis program, and obtained the flux density distribution in the gap. We here show that the performance characteristics of four-legged linear parametric motors can be improved by decreasing the thickness at the center of the common magnetic circuit.
