Stepping motor and timepiece provided with stepping motor

Abstract

Disclosed is a stepping motor including a rotor including a cylindrical rotor magnet having an M number of magnetization, M being an even number, in a radial direction, and a stator including a stator body and a coil, the stator body having a rotor accommodating space which accommodates the rotor and an N number of magnetic poles, N being an odd number, disposed along an outer periphery of the rotor, and the coil being magnetically coupled with the stator body. Further including rotor stoppers disposed at every predetermined rotation angle which is smaller than an angle obtained by dividing one rotation by a product of the N and the M and a driving pulse supplying circuit which applies driving pulses to rotate the rotor by the predetermined rotation angle to the coil.
