ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,184, issued on Nov. 25, was assigned to Siemens AG (Munich).

"Temperature determination method for magnet temperatures on magnets of electric motors" was invented by Christoph Fritsch (Pommersfelden, Germany) and Stefan Kunzel (Erlangen, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "A temperature determination method for magnet temperatures on magnets of electric motors has a test mode. A first voltage is applied to a test winding of a test motor with test magnets for impressing a first voltage-time area at first angles of a test motor rotating field. The test magnets are subject to a predefined magnet temperature. First current values are ...
