The rotor (1) with diametral magnetisation is engaged in the concentric bore hole (2), circular over the major part of its perimeter, of a stator (3) having two poles (4), each of the latter being connected to one end of a coiled core (5). The stator has two narrowed zones (6) placed symmetrically on either side of the axis (7) of the magnetic field of the coil in the bore hole. The bore hole has two notches (8) situated on radial axes (9). The radial axes (9) make an included angle differing substantially from 180 DEG . The notches (8) are of asymmetric shape with respect to the radial axes. The motor thus described makes it possible to increase the insensitivity to manufacturing tolerances, to improve the wheelwork meshing conditions and to reduce the angular offset of the rotor under a type of load. <IMAGE>
