Claims

[Claims for Utility Model Registration] (1) A magnetic resolver is installed at the bottom of an outer rotor type direct drive motor by connecting the rotors to each other and the stators, and a common bearing is placed between the motor and the magnetic resolver. An actuator characterized in that a flange is formed on the outer peripheral surface of the magnetic resolver near a position near the longitudinal center of the bearing. (2) The actuator according to claim (1), further comprising a ring case fixed to the flange, and a peripheral device attached to the actuator using the ring case. (3) The actuator according to claim (1), further comprising a peripheral device attached to the actuator by directly utilizing the flange. (4) The peripheral device is composed of a photo coupler and a light blocking member, one of which is attached to the ring case or flange, and the other is attached to a fixed part, and the actuator is such that the light of the photo coupler is blocked by the light blocking member. Claim (2) characterized in that it is an origin sensor whose origin is a rotational position.
) or the actuator described in (3). (5) The peripheral device consists of a pair of members, one member is attached to the ring case or flange, and the other member is attached to the fixed part, and the member attached to the ring case changes depending on the rotational position of the actuator. Claim (2) characterized in that the stopper is a stopper that limits the rotation range of the actuator by coming into contact with a member attached to a fixed part.
) or the actuator described in (3). (6) Claim (2) or (3) characterized in that the peripheral device is a rotational position holding means that maintains the rotational position of the rotor by generating a frictional force between the peripheral device and the ring case or the flange. Actuator listed. (7) a screw hole provided in the flange; a ring member formed in a ring shape and provided with a plurality of holes in the circumferential direction; and a ring member that is screwed to the flange using any of the holes; A claim characterized by comprising a peripheral device that can be attached to the actuator using an unused hole in the member.
(1) Actuator described. (8) The actuator according to claim (7), wherein the hole used for fixing the ring member to the flange is selectable, and the rotation angle of the actuator at which the peripheral device is actuated is set by this selection. (9) The peripheral device includes a photo coupler and a light blocking member, one of which is attached to the ring member and the other to the fixed part, and the origin is the rotational position of the actuator where the light of the photo coupler is blocked by the light blocking member. 8. The actuator according to claim 7, wherein the actuator is an origin sensor. (10) The peripheral device consists of a pair of members, one member is attached to the ring member and the other member is attached to the fixed part, and the member attached to the ring member is attached to the fixed part depending on the rotational position of the actuator. 8. The actuator according to claim 7, wherein the actuator is a stopper that limits the rotation range of the actuator by coming into contact with a member. (11) The peripheral device is a rotational position holding means that generates a frictional force between the peripheral device and the ring member to maintain the rotational position of the rotor.
(7) Actuator described.
