A thermo-magnetic motor is able to transform heat energy and magnetic energy into kinetic energy by combining permanent magnets and temperature-sensitive magnetic components. This motor is driven by heat energy and magnetic energy such as hot spring water and waste heat from power plants instead of the electric power from the outside. In this study, a shape of magnetic circuit is optimized to increase the attracting force for the temperature sensitive magnetic material and to decrease the reverse attracting force of rotation. We report some results from the analysis of three-dimensional model based on the finite element method. The result of the attracting force in the magnetization process and the optimized yoke shape design for magnetic circuits are shown.
