US Patent Issued to Bayerische Motoren Werke on June 16 for "Method and device for monitoring phase current sensors" (German Inventors)

ALEXANDRIA, Va., June 16 -- United States Patent no. 12,656,440, issued on June 16, was assigned to Bayerische Motoren Werke AG (Munich).

"Method and device for monitoring phase current sensors" was invented by Stefan Ludwig (Munich) and Christoph Sudan (Eurasburg, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "A device for checking K phase current sensors for capturing measured values of K corresponding phase currents of an N-phase, electrical load, in particular an electrical machine, with Nless than=3 and with Kgreater thanN, is provided. The device is configured to cause the N-phase load to be operated for a test period in a test operating mode in which the sum of the K phase currents, which are ...
