Force Profile Comparison for Various Stator Teeth Configurations and Translator Material in Linear Switched Reluctance Motor (LSRM)

Abstract

The objective of this paper is to improve force generated on the translator for given rating and translator design by simulating for various translator (moving assembly) materials as well as various stator teeth configurations in MagNet software. To verify the simulation results, testing is carried out on Linear Switched Reluctance Motor (LSRM) with 6/4 pole configuration having open slots, 3 phases, and 740 W. In the available motor, the magnetic parts are made up of soft pure iron. But, later in this paper the simulation results are shown proving that using easily available, low cost and relatively less permeable magnetic material (compared to soft pure iron) for translator, such as Stainless Steel (Grade 416), the force generated on translator (moving assembly) reduces only by a few newton. The similarity in force profile by using low cost material is highly desirable in industrial applications.
