PROBLEM TO BE SOLVED: To facilitate fitting of a resolver, and to improve detection accuracy, by widening partially a gap between a projection magnetic pole of a ring-shaped stator and a rotor.SOLUTION: A resolver stator structure has a constitution in which at least one first projection length (L) between each projection magnetic pole (2, 2A) is shortened furthermore than the other, or a recess (12C) and a salient (12B) are formed on the apical surface (12a) of a magnetic pole flange part (12) of at least one projection magnetic pole (2), to thereby enlarge a gap (G) between a rotor (6) and a ring-shaped stator (1), partially more than the other parts.SELECTED DRAWING: Figure 1 |
