The rotor of a stepping motor includes two axially spaced sections each formed with radially projecting and angularly spaced teeth. The angular width of the teeth of one section is approximately the same as the angular width of the pole pieces of the stator of the motor and, as a result, the motor possesses good dynamic torque, good damping characteristics and a high response speed. The angular width of the teeth of the other rotor section is greater than the angular width of the teeth of the first section so as to cause the rotor to stop in a stable detent position and to improve the stepping accuracy of the motor.
