Abstract:
A method for detecting an initial rotor angular position and starting a dynamoelectric machine having a stator and a rotor includes the steps of driving the dynamoelectric machine into partial magnetic saturation to determine the initial rotor angular position of the dynamoelectric machine, and starting the dynamoelectric machine utilizing the initial rotor angular position previously determined.
