Patent ID: 11482360

Abstract:
Systems, methods, and apparatus for secondary windings to modify a permanent magnet (PM) field of a permanent magnet synchronous generator (PMSG) are disclosed. In one or more embodiments, a disclosed system for a PMSG comprises a permanent magnet (PM) of the PMSG to rotate and to generate a permanent magnet field. The system further comprises a plurality of stator primary windings (SPW), of the PMSG, to generate primary currents from the permanent magnet field. Further, the system comprises a plurality of stator secondary windings (SSW), of the PMSG, to draw secondary currents from a power source, and to generate a stator secondary winding magnetic field from the secondary currents. In one or more embodiments, the permanent magnet field and the stator secondary winding magnetic field together create an overall magnetic field for the PMSG.
