PURPOSE:To enhance the accuracy of a motor and to reduce the number of parts by fixng two stators contacted back-to-back and two cased slidably engaged with the outsides of the two stators with a guide ring as a reference. CONSTITUTION:The first and second stators 46, 47 of the same structure at the right and left sides are welded back-to-back, and a guide ring 48 which is made of steel wire having, for example, round section with an outer diameter slightly larger than that of the stators is engaged with the recess of the outer peripheral butted parts. Then, a coil 45 is mounted on the first stator 46, the first case 41 formed with chamferred part 41A is slidably engaged with the outside of the stator 46, a coil 49 is mounted on the second stator 47, and the second case 50 formed with chamferred part 50A is slidably engaged with the outside of the stator 47. The first and second cases 41, 50 are fixed via wedge to the first and second stators 46, 47 by the guide ring 48. |
