A method and apparatus for starting a gas turbine engine using a brushless sensorless machine, the machine having a rotor and a stator with windings, the method including positioning the rotor at a desired position with respect to the stator and then energizing the windings of the stator.
I claim: 1. A method for starting a gas turbine engine drivingly coupled to a brushless and sensorless machine operating as a motor, the machine comprising a rotor and a stator having windings, said method comprising: providing DC current to at least one of the windings to position said rotor at a desired position with respect to said stator; and energizing said windings using a phased AC excitation sequence to start the brushless machine, and thereby the gas turbine engine. 2. The method as claimed in claim 1, wherein said positioning said rotor com...
