A thermo-magnetic motor is able to drive by using 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 our previous studies, the 3rd experimental thermo-magnetic motor has been developed and succeeded in steady rotation with hot water from 50 degC to 100 degC and cold water from 0 degC to 10 degC. Furthermore, a new type of the thermo-magnetic motor which is integrated the heating and the cooling lines and the magnetic circuits is designed. The heat cycle of the sealing type thermo-magnetic motor is optimized to increase the effective attracting force acting on the temperature sensitive magnetic materials by using the design of experiments method. However, the output power of the developed machine is insufficient for the practical applications. In this study, We determine appropriately the heat transfer coefficient to compute the accurate output power and investigate the cause of the effective attracting force at magnetic circuits and propose new design factors for increasing output power.
