US Patent Issued to Infineon Technologies Austria on Sept. 1 for "Parameter estimation for a permanent magnet synchronous motor" (California Inventor)

ALEXANDRIA, Va., Sept. 1 -- United States Patent no. 12,726,146, issued on Sept. 1, was assigned to Infineon Technologies Austria AG (Villach, Austria).

"Parameter estimation for a permanent magnet synchronous motor" was invented by Hamid Behjati Najafabadi (Los Angeles).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of parameter estimation for a PMSM (permanent magnet synchronous motor) includes: iteratively revising an estimate of an inductance parameter of the PMSM, until the estimate either converges to a predetermined accuracy level or diverges; and controlling a magnitude of phase currents injected into the PMSM during each iteration of revising the estimate of the inductance parameter.
