Micro-miniature motor structure

Claim 1

IN A MINATURE HYSTERESIS-TYPE SYNCHRONOUS MOTOR HAVING A CYLINDRICAL CORE, A ROTOR, A MAGNET WINDING MOUNTED ON AND SURROUNDING THE FRONT PORTION OF THE CORE, AN OUTER CYLINDRICAL FIELD RING ENCLOSING SAID MAGNET IN FLUX LINKING RELATION WITH SAID MAGNET WINDING AND HAVING REARWARDLY AXIALLY PROJECTING INTEGRAL OUTER POLE ELEMENTS ARRAYED IN A FIRST CYLINDRICAL CONFIGURATION, SAID OUTER POLE ELEMENTS DEFINING A PREDETERMINED NUMBER OF SYMMETRICALLY ARRAYED SPACES THEREBETWEEN, A STATOR SUBASSEMBLY COMPRISING: (A) A MOUNTING STRAP HAVING A CENTRAL DISC-LIKE PORTION AND AT LEAST ONE RADIALLY EXTENDING REFERENCE PORTION ASSOCIATED THEREWITH, (B) A FIRST INNER POLE PIECE HAVING A PLURALITY OF SYMMETRICALLY ARRAYED REARWARDLY PROJECTING INNER POLE ELEMENTS, (C) A SECOND INNER POLE PIECE HAVING A PLURALITY OF SYMMETRICALLY ARRAYED FORWARDLY PROJECTING INNER POLE ELEMENTS, (D) SAID INNER POLE ELEMENTS BEING LATERALLY BUTTED TO DEFINE A PLURALITY OF INNER POLE ELEMENT PAIRS EQUAL IN NUMBER TO THE SPACES BETWEEN SAID OUTER POLES. (E) SAID DISC-LIKE PORTION HAVING A PLURALITY OF LINEUP TEETH EACH HAVING AN OUTER WIDTH SUBSTANTIALLY EQUAL TO THE WIDTH OF THE SPACES BETWEEN THE OUTER POLE ELEMENTS IN SAID CYLINDRICAL FIELD RING, (F) SAID LINEUP TEETH AND SAID REFERENCE PORTION BEING EQUIANGULARLY SPACED ABOUT THE PERIPHERY OF SAID DISCLIKE PORTION TO COINCIDE WITH SAID SPACES BETWEEN THE OUTER POLE ELEMENTS, (G) SAID REFERENCE PORTION BEING A WIDTH SUBSTANTIALLY EQUAL TO THE COMBINED WIDTH OF SAID INNER POLE ELEMENT PAIRS, (H) SAID DISC-LIKE PORTION HAVING A CENTRAL BORE THEREIN, (I) ONE OF SAID INNER POLE PIECES BEING AFFIXED TO SAID MOUNTING STRAP WITH AT LEAST ONE OF ITS POLE ELEMENTS FLUSH WITH AN EDGE OF SAID REFERENCE PORTION, (J) SAID STRAP BEING SUPPORTED ON SAID CORE WITH SAID INNER POLE ELEMENTS IN FLUX LINKING RELATION WITH SAID WINDING AND WITH SAID LINEUP TEETH IN THE SPACES BETWEEN SAID OUTER POLE ELEMENTS, (K) WHEREBY SAID INNER BUTTED POLE ELEMENTS ARE ALIGNED IN A SECOND CYLINDRICAL CONFIGURATION SYMMETRICALLY OPPOSITE THE SPACES BETWEEN SAID OUTER POLE ELEMENTS.
