  • HIGH-PRECISION ROTOR POSITION DETERMINATION FOR USE IN POSITION AND/OR TORQUE CONTROL AT LOW SPEED
    Publication number: 20250105766
    Abstract: An assembly for determining the electrical angle of a rotor in an electrical machine is provided, such as a wind turbine generator. The assembly includes: (a) an encoder having an encoder wheel configured to contact a surface of the rotor to obtain relative rotor rotation information based on rotation of the encoder wheel, (b) an electrical angle observer configured to provide an absolute electrical angle, and (c) a processing device coupled to communicate with the encoder and the electrical angle observer and configured to determine the electrical angle of the rotor based on the relative rotor rotation information and the absolute electrical angle. Furthermore, a wind turbine generator including such an assembly, and a method of determining the electrical angle of a rotor in an electrical machine, such as a wind turbine generator, are provided.
