Claims

[Scope of utility model registration request]

a first stator coil that is attached at regular intervals in the circumferential direction of the outer circumferential surface of a cylindrical first stator core and is sequentially excited in the circumferential direction to sequentially shift the generation point of magnetic flux in the circumferential direction; an end plate fixed to both ends of the stator core; a cylindrical output having both ends rotatably supported by the end plates and a cylindrical portion coaxially disposed outside the first stator core; axis and
a first internal gear coaxially formed on the inner peripheral surface of the output shaft; and a first internal gear loosely fitted in a first gap between the first stator core and the output shaft. A first drive ring in which a first external gear having fewer teeth than the gear is formed on the outer peripheral surface, a plurality of first roller pins protruding from an end surface of the first drive ring and attached in a circumferential direction, and the first roller pin. By loosely fitting and supporting the first roller pin, which is provided on the end plate corresponding to a second stator core having an annular shape disposed outside the output shaft concentrically with the output shaft and fixed to the end plate, and the second stator core second stator coils that are attached at regular intervals in the circumferential direction on the inner circumferential surface of the second stator coil and are sequentially excited in a circumferential direction opposite to the excitation direction of the first stator coil, thereby sequentially shifting the locations where magnetic flux is generated in the circumferential direction; a second external gear coaxially integrally formed on the outer peripheral surface of the output shaft; and a second external gear loosely fitted in a second gap between the second stator core and the output shaft. a second drive ring in which a second internal gear having a larger number of teeth than the toothed gear is formed on the inner peripheral surface;
The second drive ring, a plurality of second roller pins protruding from an end surface of the second drive ring and attached in the circumferential direction, and provided on the end plate corresponding to the second roller pin to loosely fit and support the second roller pin. and a second bushing that allows the second drive ring to swing within the second gap in a state where the second internal gear is meshed with the second external gear. Low speed high torque motor.
