PROBLEM TO BE SOLVED: To provide a double rotor stepping motor.SOLUTION: A stepping motor 10 includes two rotors 12 and 13 that rotate in opposite directions so as to generate a low-amplitude movement between one of the rotors 13 and a stator 11. The first rotor 12 includes a first set of teeth 121 distributed at a first pitch p1 and a second set of teeth 122 distributed at a second pitch p2. The stator 11 includes N stator contacts 111 to 114 including a plurality of teeth distributed at the pitch p1, distributed at a third pitch, and able to cooperate with the teeth 121 of the first set. The second rotor 13 includes N rotor contacts 131 to 134 including a plurality b of teeth distributed at the pitch p2, distributed at a fourth pitch, and able to cooperate with the teeth 122 of the second set of the first rotor. |
