Summary:

Carrier Injection Sensorless (CIS) rotor position estimation for electric machines depends on the rotor saliency "seen" from the stator terminals. Compared to permanent magnet and induction machines, wound field synchronous machine rotor saliency characteristics are more complex. At typical carrier frequencies subtransient characteristics dominate. Injecting positively rotating carrier voltages at the stator terminals of a machine having rotor saliency produces both positively and negatively rotating carrier currents. The impedances relating currents to injected carrier voltages are derived from the dq reference frame synchronous machine model. Analytical results are compared to simulation and limited test results for an aircraft starter/generator
