Abstract:
1. A resin molding method for protecting a winding of a resolver comprising: providing a first mold member, a second mold member, and a movable part, wherein the movable part is disc shaped and is attached with multiple pins to a body of the first mold member so that the movable part can be moved in an axial direction with respect to the mold members; urging the movable part toward the second mold member with springs such that the movable part is closely engaged with the second mold member while an annular stator of the resolver is sandwiched between the mold members in a manner such that the annular stator surrounds the movable part; injecting a fused resin molding material into a space formed between the first mold member and the second mold member, when the stator, which includes the winding, is sandwiched between the first mold member and the second mold member to cover the winding with the molding material; wherein the method further includes locating the pins within the springs.
