A motor-converter with clutch-plates comprising: a motor-shaft (1); at least a trapezoid-race, diameter variable, motive pulley (25), formed by two trapezoid, opposite half-pulleys (21, 23) idly-mounted on said motor-shaft (1); a chill (7), mounted on said motor-shaft (1) in coaxial alignment with at least one (21) of said half-pulleys, and comprising on the parallel side (20), facing said half-pulley (21), a friction clutch plate (22) and, on the opposite side (20'), a curved surface wall; said chill (7) comprising a lid (4) having a supporting housing (4'); a dragging bell (5) integral with the motor-shaft (1); masses (19) caused to move by said bell (5) and radially sliding in centrifugal direction along the curved surface wall of the chill (7); at least a trapezoid race, diameter variable, driven pulley (26) formed by two trapezoid, opposite half-pulleys (35, 36), and connected to said motive pulley (25) through a trapezoid belt (24); and means for the progressive recovery of the increase in clearance (17) due to the progressive reduction due to wear of the thickness of the friction clutch-ring (10) consisting of several removable shims (9) interposed between the elongated guide (2) and the motor-shaft (1). <IMAGE>
