The double rotor stepping motor (30) has stator (31) having stator contacts, first rotor (32) having first set of teeth distributed at first pitch, and second set of teeth distributed at second pitch, and second rotor (33) having rotor contacts. The stator contacts are distributed at third pitch. The rotor contacts are distributed on second rotor at fourth pitch, and are aligned with teeth of second set, such that passage from one alignment to consecutive alignment causes second rotor to move in direction opposite movement of first rotor with respect to first rotor by predetermined pitch. |
