Abstract
The object of the present invention is to provide a rotary electric machine that provides bobbins with good assembling efficiency and allows no dislocation of the stator. A motor,comprises a case,, a stator,secured inside the case,, a rotor,formed into one piece with a rotating shaft,. The stator,comprises stator yokes,and the stator yokes are secured in a radial manner in the case,. Furthermore, resin,is filled in between the stator,and the case,with a space for the rotor being left. The stator yokes,comprise a salient pole,, a bobbin,for holding the salient pole,, and a magnetic wire,wound around the bobbin,. A collar,of the bobbin,is formed so as to contact each other with notches,formed on two, upper and lower edge portions. Accordingly, combining two bobbins,allows through-holes,penetrating the collar,thereof. This allows the stator to be firmly assembled, provides good assembling workability, and allows no dislocation owing to resin flowing when the resin is injected.
