Abstract
This paper presents a new magnetic actuator for flexible motion of the human being. The actuator is made by connecting many actuator-units. The actuator design is based on the magnetic circuit method. The generated torque of the unit is experimentally confirmed to prove the validity of the design, and the discrepancy between designed value and measured value is about fifty percent. A new circuit model is then proposed, and a numerical analysis to the new circuit shows that the discrepanccy is reduced by ten percent. Moreover, movable range of actuator is experimentally proved to close the designed value.
