Abstract
A rotating electrical machine (motor or generator) includes a controller evaluating rotor displacement using a combined winding that also provides for torque coupling to the rotor through the use of a model relating rotor offset to at least one of resistance, inductance, or back-EMF measured through a combined winding.
