Claims

[Scope of utility model registration request]

an output member rotatable via two bearings provided at both ends and provided with a rotational force sufficient to rotate a driving object; a rotating frame body fixed concentrically with the output member; A fixed base provided to hold the two bearings, two magnetic objects provided at a predetermined distance on the same circumference of the rotating frame body, and a part of the fixed base body. , the two magnetic objects are composed of one magnetic movement position detection element disposed on the same straight line in the circumferential direction, and the two magnetic objects and the one magnetic movement detection element are arranged on the same straight line in the circumferential direction. A motor actuator in which a set of position detecting sections is constructed, and several sets of the set of position detecting sections are arranged in the axial direction of the fixed frame body and the rotating frame body.
