Abstract
A ring (16) of non-magnetic material is engaged in the opening bounded by the pole shoes (6,7) of a pole plate (5), between the pole shoes and the rotor (12). A magnet (18) serving to define the position of rest of the rotor is mounted on this ring, which can be accurately positioned by means of a slot (11) provided in the pole plate.
