トルクモータ。 An output shaft rotatably supported by a casing via a needle roller bearing and having a hollow shape, an output gear coaxially formed integrally with the output shaft, and an output gear surrounding the output gear and concentric with the output shaft. An annular stator core is fixed to the casing, and the stator core is attached to the inner circumferential surface of the stator core at regular intervals in the circumferential direction and is sequentially excited in the circumferential direction, thereby sequentially moving the locations where magnetic flux is generated in the circumferential direction. a stator coil to be shifted; a drive ring having an internal gear having a larger number of teeth than the output gear; and a drive ring loosely fitted into a gap between the output gear and the stator core; and a circumferential direction of an end surface of the drive ring. A plurality of roller pins are attached to protrude from the end face, and a plurality of roller pins are provided in the casing corresponding to the roller pins, and the roller pins are loosely fitted and supported, so that the drive ring is connected to the drive ring in a state in which the internal gear is meshed with the output gear. A low-speed, high-torque motor characterized by being equipped with a bushing that swings within a gap.
