Abstract
A system and method for determining rotor shaft position of high voltage permanent magnet AC synchronous machines using auxiliary windings utilizes a permanent magnet AC synchronous motor including a stator having a main set of coils and an auxiliary set of coils. A drive controller including a digital signal processor in communication with the motor utilizes a current and voltage measurements from the main and auxiliary coils to determine the position of the rotor shaft in a sensorless mode.
