3-D Numerical Analysis and Test Result of a Short Primary Linear Reluctance Motor

Abstract

A 3-D boundary integral equation is applied to a model of a short primary linear reluctance motor. The model is a double-sided construction where the primary member is surrounded by a set of secondary iron plates on both sides. Six kinds of different secondary geometries are calculated and their characteristics are discussed. For the confirmation of calculation results, a test machine is manufactured. Test results are compared with calculated ones. Furthermore, the static thrusts of a single-sided machine and a coreless PMLSM are measured and compared with that of the double-sided machine
