This paper reports the static and the kinetic thrust characteristics of a linear oscillatory actuator with a permanent magnet at low and room-temperatures. The static and kinetic thrust with respect to the position were measured with a variable exciting current. Room-temperature was maintained by water cooling, and low temperature was obtained by using liquid nitrogen. The detent force at low temperature was larger than that at room-temperature. The static thrust excluding the detent force at roomtemperature was larger than that at low temperature, and a linear dependence at low and room-temperatures was exhibited between the static thrust excluding the detent force and the magnetomotive force.
