One or more first stoppers are secured to the stator and a shaft is rotatably secured in a bearing forcibly inserted in a bore in the upper portion of the base. A hub of a rotor is secured to the shaft and a cylindrical wall extends downwardly at the rim of the hub and carries a magnet facing the stator with an air gap therebetween. A second stopper is secured to the rotor, to face the first stopper to retain the rotor in the axial direction. The second stopper has a flange over which the first stopper is placed with slight clearance. An elastomer rests on the first stopper and carries guides which extend in slots in the rotor to engage and center a hole in a disc.
