PCT No. PCT/FR85/00121 Sec. 371 Date Dec. 23, 1985 Sec. 102(e) Date Dec. 23, 1985 PCT Filed May 21, 1985 PCT Pub. No. WO85/05506 PCT Pub. Date Dec. 5, 1985.The rotor (1), which has magnets (3) in particular of the rare earth-cobalt type, is surrounded by a hoop formed by a metal which has been cold work-hardened and has a high elastic strength so as to form a sleeve which exerts on the subjacent magnets a high pre-stressing force.
