Claim:
1. An integrated motor-gear drive unit for transmitting rotational movement from a motor output shaft with cycloidal reduction to an outer rotatable body, the integrated motor-gear drive unit comprising: a. a mounting carrier body and a secondary carrier body, b. at least two carrier pin devices which structurally connect the mounting carrier body and the secondary carrier body to form a combined carrier body; c. an outer rotatable body rotatably supported on the mounting carrier body and on the secondary carrier body; d. a motor having a rotatable motor output shaft, wherein the motor is one of: e. at least one cycloidal gear disc, wherein said at least one gear disc has at least two holes corresponding to said at least two carrier pin devices, and wherein each carrier pin device protrudes through a corresponding hole; f. an eccentric body rotatably supporting the cycloidal gear disc and wherein the motor output shaft is arranged for rotating the eccentric body within the cycloidal gear disc, g. wherein each said at least one gear disc is provided with an external gear profile and the outer rotatable body is provided with an internal gear profile and wherein the external gear profile of the cycloidal gear disc meshes with the internal gear profile of the outer rotatable body for transmitting rotational motion of the motor output shaft to the outer rotatable body, wherein the internal gear profile of the outer rotatable body is formed by an internal gear teeth profile and the external gear profile of the cycloidal gear disc is formed by an external gear teeth profile; h. wherein the eccentric body is rotatably drivable by at least one of: i. wherein an external profile is provided on one of: j. wherein an axial opening formed in the corresponding eccentric body is provided with a corresponding internal profile.
