Abstract
A VR resolverand an MR sensorare mounted to a shaftThe VR resolverand the MR sensorare formed so as to have a shaft angle multiplier of not less than 2. The difference of the shaft angle multiplier between the VR resolverand the MR sensoris made to be 1. An absolute angle of the shaftis calculated based on a difference between an angle calculated from an output of the VR resolverand an angle calculated from an output of the MR sensorSince the VR resolverand the MR sensorhave a different failure mode, redundancy against failure is reliably obtained.
