PROBLEM TO BE SOLVED: To develop a two-phase hybrid type stepping motor of high torque and high resolution, which is small and inexpensive.;SOLUTION: In a two-phase hybrid type stepping motor, a stator 1 and a hybrid type rotor 6 are freely rotatably arranged opposite each other, the stator being such that four coil poles are provided at a pitch of 90 degrees in an inward direction from the middle of each of four sides of an approximately square yoke part and six teeth are radially provided at the leading end of them, the rotor being such that two rotors 6 with 25 teeth formed from a magnetic material, approximately disk-like permanent magnets 8 axially magnetized by their being 180° displaced from each other at an electric angle, are sandwiched via an air gap and a rotation shaft 9 are provided in the central parts of them.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
