The invention relates to a magnetoelectric claw rotor of the type comprising parts made of magnetic material forming the poles of the rotor, and parts made of non-magnetic material for separating poles of opposite polarity, all confined in a common hollow cylindrical case of non-magnetic material. The rotor comprises two single-pole end parts of magnetic material and of opposite polarity, at least one intermediate part of magnetic material, and parts of non-magnetic material, each single-pole end part has a chamfered pole, and two plane lateral faces disposed symmetrically about the plane of symmetry of the chamfered pole, the, or each, intermediate part has two poles of opposite polarity, having the same shape as the pole of the end parts, with each pole being separated from the facing pole by a non-magnetic part of shape complementary to the two poles, the cylindrical case having as many through windows as there are poles, each window being occupied by a distal tube element of magnetic material having the same polarity as the pole with which it is associated.

[ We claim:] [1.] A magnetoelectric claw rotor of the type comprising magnetic material parts forming the poles of the rotor, and non-magnetic material parts for separating poles of opposite polarity, all confined in a hollow cylindrical casing of non-magnetic material, the rotor comprising two single-pole end parts of magnetic material and of opposite polarity, and a part of non-magnetic material, each single-pole part having a circularly cylindrical hub of radius substantially equal to the inside radius of the cylindrical case, and having a free end and a chamfered pole, said chamfered pole having a longitudinal face of the same radius as the hub, a sloping transverse face forming the chamfer relative to said longitudinal face, and two plane lateral faces disposed symmetrically about the plane of symmetry of the chamfered pole, and converging towards each other going from the longitudinal face towards the sloping face, transverse shoulders being formed between the hub and said plane lateral faces, the two parts of magnetic material being disposed on the same axis, with their sloping faces facing each other, the non-magnetic part being disposed between the facing sloping faces, and being complementary in shape to the two magnetic material parts such that the set of magnetic material parts and the non-magnetic material part constitutes a solid circular cylinder of radius substantially equal to the inside radius of the non-magnetic cylindrical case, the cylindrical case having two through windows each facing a respective one of the longitudinal faces of the magnetic material parts, each window being occupied by a distal tube element of magnetic material having the same polarity as the magnetic material part with which it is associated.
