Abstract: This invention is to provide a stator structure for a rotary electric machine comprising poles of an armature core made of soft magnetic material and bobbins wound with coils at the respective poles and inserted into the poles in which the bobbin wound with the coils are mounted at the stator poles without decreasing motor characteristics. The material of a collar part (auxiliary pole tooth or extrapolation pole tooth) of a bobbin opposed to a rotor is formed of resin filled with soft magnetic material to improve the characteristics of a rotary electric machine. It is also effective to form the end of the collar part of the bobbin of a ferromagnetic material. Since a magnetic flux is also passed through the auxiliary pole tooth or the extrapolation pole tooth provided at the bobbin, the magnetic reluctance of the magnetic path to the rotary pole can be reduced.
