ALEXANDRIA, Va., Aug. 26 -- United States Patent no. 12,401,302, issued on Aug. 26, was assigned to Infineon Technologies Austria AG (Villach, Austria).
"Adaptive motor controller" was invented by Hamid Behjati Najafabadi (Los Angeles).
According to the abstract* released by the U.S. Patent & Trademark Office: "A controller for a permanent magnet synchronous motor includes a first control loop having a first filter. The first filter has a back-EMF voltage vector input, a magnetic flux vector output with a constant phase shift that is independent of motor speed, and an amplitude response that is inversely proportional to rotor electrical frequency. The first control loop is configured to: generate an adjusted magnetic flux vector from the ...
