ALEXANDRIA, Va., Jan. 28 -- United States Patent no. 12,537,398, issued on Jan. 27, was assigned to Lin Engineering Inc. (Morgan Hill, Calif.).
"Eight-stator-pole, bipolar, 3.6-deg hybrid step motor" was invented by Ted T. Lin (Saratoga, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A two-phase bipolar 3.6deg step motor is described in which the stator winding assembly has eight stator poles organized into decoupled phase groups with two distinct angular pole separations, 14.4degx[(4nplus-minus1)/4] between poles of the same group, and 14.4degx[(4mplus-minus1)/2] between adjacent poles of different groups, where n and m are positive whole numbers. Three stator teeth on each stator pole have a stator ...
