A rotation angle sensor includes: (a) a multi-resolver housing with a high precision structure; (b) stator terminals that do not cause deformation or loosening of terminal pins from the substrates to which they are attached; and (3) a signal line connection structure that is not affected by thermal stress. The housing () includes divisional housings (), and one resolver is installed in each of the divisional housings (). The divisional housings () are assembled by aligning respective openings therein in an axial direction. The lead lines of stator windings are connected to printed circuit substrates () installed on insulators (), and pins () connect the printed circuit substrates () to a connecting signal output line via flexible connectors ().

Multi-resolver rotation angle sensor with integrated housing

A high-accuracy, 1X VR resolver includes a first rotor portion having (N&#x2212;1) salient poles, where N is an arbitrary integer not less than 3, a second rotor portion having N salient poles, a first stator portion having an input coil and an output coil for a shaft angle multiplier of (N&#x2212;1)X are provided, and a second stator portion having an input coil and an output coil for a shaft angle multiplier of NX. A first resolver unit composed of the first rotor portion and the first stator portion, and a second resolver unit composed of the second rotor portion and the second stator portion are disposed in front and rear stages, respectively. The output coil of the stator portion in the front stage is connected to the input coil of the stator portion in the rear stage in such a manner that the output coil of the stator portion in the rear stage outputs an output signal for a shaft angle multiplier of 1X.
