ALEXANDRIA, Va., June 9 -- United States Patent no. 12,651,936, issued on June 9, was assigned to Siemens AG (Munich).
"Four-pole synchronous reluctance motor" was invented by Regina Bach (Hendungen, Germany) and Johannes Schmidt (Gerbrunn, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "A synchronous reluctance motor, in particular a four-pole synchronous reluctance motor includes a stator with 48 stator grooves for receiving a winding system; a reluctance rotor, which is spaced apart from the stator by an air gap. The reluctance rotor has axes with a high magnetic conductivity (d-axis) and axes with low magnetic conductivity (q-axis). Provision is made for an arrangement of magnetically conductive f...
