ABSTRACT:
A synchronous resolver has: a stator including a plurality of stator poles disposed at regular intervals along the circumferential direction of a ring-shaped stator base portion, the stator poles comprise a plurality of phases; coil bobbins former-wounded stator coils therearound are respectively fitted with and mounted on their associated ones of the stator poles; and, a rotor shiftable in angle with respect to the stator to thereby vary a reluctance component in a gap existing between the stator and the rotor, wherein the coil bobbins are set the positions of the stator coils freely in such a manner that the resolver signals of the respective phases balance well.
