Outline of Final Research Achievements

In this research subject, as the research of actuators suitable for miniaturization and high thrust, the following was done. (1) A compact high-thrust actuator including temperature-sensitive magnetic material parts, permanent magnet and Peltier element without coils has been proposed. The proposed actuator demonstrated to be able to generate large constant thrust with low power consumption. (2) A control method suitable for the proposed actuator explained in (1) was presented. The experimental result shows that the combination of the actuator and the control method provides the error less than or equal to 0.02 mm. (3) A new actuator combining a conventional electromagnetic force actuator and a temperature sensitive magnetic material part has been proposed. The experimental results indicate that the actuator can generate large constant thrust with ultra low power consumption.
