MAGNETIC ACTUATOR, MAGNETIC ACTUATOR OPERATION METHOD, AND ENCAPSULATED ENDOSCOPE USING THE SAME

摘要

It is possible to provide a magnetic actuator assuring a degree of freedom of design and having a high energy efficiency, a magnetic actuator operation method, and an encapsulated endoscope using the same. The magnetic actuator includes a housing (2), a rotating/shifting magnet (6), a fixed magnet (7), coils (3, 4) arranged outside the housing (2), and an induction region (2a) arranged in the housing (2). The rotating/shifting magnet (6) and the fixed magnet (7) can be relatively rotated in a plane containing the magnetization direction. The coils (3, 4) generate a magnetic field for relatively rotating the rotating/shifting magnet (6) in the direction to generate a repelling force between the rotating/shifting magnet (6) and the fixed magnet (7). The induction region (2a) controls the direction of the relative movement of the rotating/shifting magnet (6) by the generated repelling force.
