PROBLEM TO BE SOLVED: To facilitate manufacture by composing a stator transformer of a ring-like flange and a ring plate of magnetic material provided independently on the stator case and forming the ring plate by laminating a plurality of ring pieces thereby decreasing the number of parts. SOLUTION: A stator case 1 made of a nonmagnetic material is provided with a ring-like detector stator 3 and a ring-like stator transformer 5 having a stator transformer winding 4 is disposed adjacent to the detector stator 3. More specifically, the stator case 1 is made of a magnetic material and a ring- like flange 30 is formed integrally therewith and a step 31 is formed oppositely to the flange 30. The step 31 is provided with a pressed ring plate 32 independently from the stator case 1 and oppositely to the flange 30 wherein the ring plate 32 is formed by laminating a plurality of pressed ring pieces 32a. |
