Abstract
A transmission assembly has an integrated torque machine including a torque machine stator and a torque machine rotor. The torque machine rotor includes at least one set of rotor magnets. An integrated rotational position sensor is configured to monitor rotational position of the torque machine rotor in relation to the torque machine stator. The integrated rotational position sensor includes a sensor rotor element and a sensor stator element. The sensor rotor element includes at least one set of sensor rotor magnets. The sensor rotor element is positioned such that the at least one set of sensor rotor magnets are aligned with respect to a rotor pole of the at least one set of rotor magnets of the torque machine rotor. The sensor stator element is positioned such that the sensor stator element is aligned with a magnetic axis of the torque machine stator.
