The rotor of the electromagnetic motor comprises a shaft (5) containing a cavity (5a) and a magnet (6) mounted in this cavity. The magnet has the shape of a parallelepipedal bar whose axis points along the line II-II'. It is magnetised along this axis. The shaft forms, together with the pinion (9) and the pivots (13 and 14), a one-piece construction. It is preferably made of plastic. The magnet, owing to its simple shape, is easily machined even from a material which is difficult to section such as samarium-cobalt. The shapes of the shaft and the magnet lend themselves particularly well to automatic mounting. <IMAGE>
