Abstract
PURPOSE:To promote efficiency with a small and thin type by incorporating a circular center axis furnished with a field pole and a concentric shaft as a unit to a stator. CONSTITUTION:A rotor 2 of a rotary actuator is constituted of a cylindrical permanent magnet 4 magnetized to two poles, a magnetic substance ring 6 by circular iron system sintering and a bobbin made of resin, and the permanent magnet 4 to the outer perimeter and the magnetic substance ring 6 to the inner perimeter are respectively arranged to form together as a unit by a resin member 8. And, a stopper 10 and a slit 12 regulating an angle of rotation of the rotor 2 are formed to the underside of the resin member 8. The stopper 10 is properly connected to a cushion 25 and limits the rotation of the rotor 2 to the range of a specific angle when the rotor 2 is fitted into a loosely rotor fitting section 22 formed in a base member 20 and rotates. And, a stator 40 has four cores 42-48 on the positions at right angles each other, and the coils 42c-48c are wound and loaded. Therefore, a small and thin type of rotary actuator can be constituted.
