    Abstract: A ROTOR OF A MOTOR COMPRISES A PLURALITY OF SETS OF PERMANENT MAGNETS (8A, 8B) EMBEDDED IN THE ROTOR (3), AND EACH SET INCLUDES A PERMANENT MAGNET (8A) AT THE INNER SIDE AND ANOTHER PERMANENT MAGNET (8B) AT THE OUTER SIDE WITH A DISTANCE BETWEEN THEM. EACH PERMANENT MAGNET (8A, 8B) IS FORMED LIKE AN ARCH PROJECTING TOWARDS THE CENTER OF THE ROTOR (3). THEN, MAGNETIC FLUX BECOMES EASY TO FLOW THROUGH AN INTERVAL BETWEEN THE PERMANENT MAGNETS (8A, 8B) AT THE INNER AND OUTER SIDES, AND THE INDUCTANCE IN Q-AXIS IS ENLARGED. THEN, THE RELUCTANCE TORQUE IS GENERATED IN ADDITION TO THE MAGNET TORQUE, AND THE MOTOR HAS A HIGH TORQUE AND A HIGH OUTPUT POWER.

    Abstract: A motor has a stator having a plurality of teeth for receiving windings, a yoke connected to each tooth, and a rotor having permanent magnets facing the stator. An inner wall surface of each tooth faces the rotor with an air-gap therebetween. Each tooth is separated from an adjacent tooth by a slot-open-section extending between a tailing end of the tooth and a leading end of the adjacent tooth. The inner wall surface of each tooth has an arc extending from a center of the slot-open-section toward the tailing end. The air-gap at the tailing end of each tooth is greater than the air-gap at the leading end of each tooth. The inner wall surface of each tooth includes a straight-line tailing section extending from the center of the slot-open-section toward the leading end. The straight-line tailing section extends tangentially from the arc.
