PROBLEM TO BE SOLVED: To realize a small size and high performance motor which is easy to assemble. SOLUTION: A stator core 3 has a plurality of poles 31. An aperture 34 is formed in the center part of the stator core 3. Three screw holes 35 are formed around the aperture 34. The respective poles 31 are composed of arm parts 32, on which coils are wound and pole end parts 33 which are provided on the tips (outer circumference ends) of the arm parts 32 and face the inner circumferential surfaces of the permanent magnets of a rotor. The pole end part 33 is formed by bending a plate-shaped member in a direction approximately perpendicular with respect to the arm part 32. The length of the pole end part 33 in the axial direction of a rotor shaft is larger than the thickness (length in the axial direction) of the arm part 32. The respective bottom surfaces of a pair of such stator cores 3 as described are jointed with each other for constituting a stator. |
