Claims

[Scope of utility model registration request]

A rotating movable body including a disk-shaped yoke member fixed perpendicular to the rotating shaft, and a rotary movable body having a magnetization direction in the axial direction of the rotating shaft, flat in the magnetization direction, and adjacent to each other have a magnetization direction. a plurality of sector-shaped permanent magnets fixed to the yoke member of the rotary movable body in opposite directions and equally dividing the circumference; a fixed base member that pivotally supports the rotation axis of the rotary movable body; A plurality of windings each having a plurality of radially extending conductive wires wound in a plane are fixedly installed on a plane perpendicular to the rotation axis of the fixed base member, facing the flat sector-shaped permanent magnet. A rotary actuator comprising a planar coil member in which a plurality of conducting wires are arranged in the same number of circles as permanent magnets and extend in the radial direction of each winding, and are arranged in parallel between adjacent windings.
