Abstract

This paper deals with tubular type linear oscillatory actuator with axially magnetized permanent magnet. The magnetic field distribution is predicted using a two-dimensional analytical solution derived in terms of magnetic vector potential and cylindrical coordinate system. Using this result, trust and flux linkage and back emf are derived. The results of predictions from the analysis are compared with corresponding finite element method.
