Abstract
An example method of initiating operation of a wound field synchronous machine in a motoring mode includes estimating an initial position of a rotor of a wound field synchronous machine using a carrier injection sensorless stimulation signal. The method tracks an operating position of the rotor based on current harmonics of the wound field synchronous machine. The method also calibrates the tracking using the initial position.
