A rotary motor with an improved driving torque comprises a base plane (tautau) defining a first axis of rotation (R-i), an annular member (2, 20) which is adapted to move in the plane (tautau) about a second axis of rotation (R2) and to be associated with power take-off means, the annular member (2, 20) having an inner peripheral surface (3, 30) and an outer peripheral surface (4, 40), constraint means (5, 50) for bounding the movement of the annular member (2, 20) in the plane (tautau), a plurality of actuators (6, 6', 6", 6"'; 60, 60', 60", 60"' ) adapted for sequential interaction with the annular member (2, 20) to promote their precessional motion about the first axis (R-i). The actuators (6, 6', 6", 6"'; 60, 60', 60", 60"') are designed for direct interaction with one of the peripheral surfaces (3, 4; 30, 40) to define therewith at least one contact point (P-i) at which they exert a first friction force (F-i). The constraint means (5, 50) have lateral edges (7, 70) designed for interaction with the other of the peripheral surfaces (3, 4; 30, 40) to define therewith at least one second contact point (P2) at which the actuators (6, 6', 6", 6"'; 60, 60', 60", 60"') exert a second friction force (F2), for promoting, in combination with the first force (F-i), a driving torque. |
