<p>Diphased stepping motor with axially magnetized rotor. This motor comprises two stationary magnetic circuits (4, 5) having each two branches of which at least one is coupled to an electric control coil (12, 13). The branches (6, 8) of each circuit are interconnected to one end, the free end of those branches forming the polar portions arranged facing each other on either side of a disk shaped rotor (1), presenting on each phase 2N magnetized areas of alternating polarity. Each of the polar portions (6, 8) of one of the circuits is provided so as to have the same shape as the corresponding polar portion of the other circuit. The invention applies particularly to motors used for driving clockworks.</p> |
