Claims

[Scope of utility model registration request]

A stator core fixed to the outer periphery of the hollow pipe,
stator coils that are attached to the outer circumferential surface of the stator core at regular intervals and are sequentially excited in the circumferential direction to sequentially shift the locations where magnetic flux is generated; and fixed to the outer circumference of both ends of the hollow pipe, respectively. and an end plate having a cylindrical portion coaxial with the hollow pipe formed on the outside of the hollow pipe, and an outer circumferential surface of both ends rotatably attached to an inner circumferential surface of the cylindrical portion of the end plate via a bearing. a cylindrical output shaft that is supported and has an internal gear formed on its inner peripheral surface; and external teeth that are loosely fitted into the gap between the stator core and the output shaft and have a smaller number of teeth than the internal gear. A drive ring having gears formed on its outer circumferential surface; a plurality of roller pins protruding from the end surface in the circumferential direction of the end of the drive ring; and a plurality of roller pins provided on the end plate corresponding to the roller pins and supporting the roller pins with loose fit. A low-speed, high-torque motor comprising: a bushing for swinging the drive ring within the gap in a state where the external gear is meshed with the internal gear.
