Abstract
A multi-turn angle sensor includes rotors, each of which rotates in a different manner with respect to an input shaft, and a common stator portion. The rotors and pole teeth disposed around the rotors form each of resolvers. At least two of the resolvers are arranged on a single plane vertical to the rotation central axis of each of the rotors. The common stator portionsurrounding each of the rotors is formed by laminating electromagnetic steel sheets, each of which has an identical shape including a plurality of sets of pole teeth corresponding to each of the rotors. A single length of unspliced electrical wire is wound around each of the pole tooth sets. This facilitates automation of assembly.
