PURPOSE:To eliminate machining burrs in case of polishing the pole surfaces by filling resin in grooves formed on the pole surfaces of a stator stack. CONSTITUTION:Resin 9 which contains powder insulating material and adhesive is filled in grooves 3b of the pole surface 5 of a stator stack 1 and the grooves 4b of the pole surface 6 of a rotor stack 2. The resin 9 is bondable with the stacks 1, 2 to be adequately hard. Since the pole surfaces 5, 6 of the stacks 1, 2 are machined integrally with the resin 9 filled in the grooves 3b, 4b at polishing time, the machining burrs can be reduced. |
