PROBLEM TO BE SOLVED: To improve a power factor of a small-sized toothed core motor and to increase a torque (thrust). SOLUTION: The small toothed core motor includes a pole row having poles 22 in which N-poles and S-poles are alternately disposed, a core 11 having a tooth row relatively movable oppositely to the pole row at a predetermined average distance in which teeth 12 and slots 13 are alternately disposed along a direction of the aligning N-poles and S-poles at an part opposed to the pole row, and a coil for generating a thrust between the pole row and the tooth row by supplying current. The motor also includes a magnetic short circuiting implement 15 having conductors 14 and magnetic elements so as to suppress the arrival of magnetic fluxes generated from the poles 22 opposed to the slots 13 at the core 11.
