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.
