Abstract

Abstract — Several well-known analytical techniques exist for the force profile analysis of permanent-magnet linear oscillating motors (PMLOMs). These techniques, however, make significant simplifications in order to obtain the magnetic field distribution in the air gap. From the field distribution, the force profile can be found. These widely used techniques provide a reasonable approximation for force profile analysis, but fail to give really accurate results in the sense of the exact shape of the force profile caused by effects that due to simplification are not fully included. To obtain the exact shape for the force profile in these cases, the computationally expensive finite-element method (FEM) is often applied. In this from the resulting field distribution, the force profile is calculated by means of the Maxwell stress tensor. The objective of this paper is to determine the forces for aluminium mover embedded with Nd-Fe-B Rare Earth Permanent Magnet experimentally and analytically through FEMLAB6.2 WITH MATHWORKS software and develop a microcontroller based IGBT Inverter for its control. In this paper Development, Finite Element Analysis of Magnetic field distribution, performance, control and Testing of
