Abstract
There is a driving shaft in the case, with a wheel at its end, a driven shaft with a driven pulley, and a clutch unit between the two shafts designed to perform driving or braking of the driven shaft as required. There is a stationary friction surface at a distance from the driving wheel, and a clutch plate between the two, rigidly connected to the driven shaft; it has two friction surfaces, and can be coupled with the driving wheel or it may be used for braking by contact with the stationary friction surface. At least two induction motors (55, 60) running at a constant speed are mounted in the case (11); they are so coupled through intermediate elements (52, 65) with the shaft (47), that it rotates at a speed approx. equal to the sum of speeds of individual motors.
