摘要： The present invention provides a permanent magnet rotating electric machine that comprises a stator, into which concentrated wound armature windings are inserted in such a way as to surround a plurality of teeth formed in a stator core, and a rotor having rare earth permanent magnets inserted into a plurality of permanent magnet holes, which are formed in a rotor core and used for accommodating permanent magnets. In this permanent magnet rotating electric machine, the permanent magnets are each shaped like a convex “V” or “U” with respect to the shaft of the rotor. Moreover, a ratio of the width W1 of an interpole core between the permanent magnets to the width Xg of the gap between the stator core and the rotor core is set in such a manner as to satisfy the following condition: 0.8≦W1/Xg≦13.2. Thus, even when this rotating electric machine is driven by a position sensorless inverter in the case of 120 degree energization, the system efficiency is enhanced.

摘要： A permanent magnet rotating electric machine that comprises a stator, into which concentratively wound armature windings are inserted in such a way as to surround a plurality of teeth formed in a stator core, and a rotor having permanent magnets accommodated into a plurality of permanent magnet inserting holes formed in a rotor core. In this rotating electric machine, the permanent magnets are convex V-shaped or U-shaped with respect to a rotor axis. Moreover, nearly V-shaped recess portions, each of which is placed between adjacent poles, are formed in outer circumferential surface portions of the rotor core. Thus, torque caused by magnetic flux due to the magnets is increased, while armature reaction magnetic flux generated by an armature current is reduced. Consequently, q-axis inductance is reduced, so that armature current commutation is quickly achieved. Thus, the permanent magnet rotating electric machine using the stator employing concentrated windings and also using the magnet-embedded rotor is stably driven even when driven by a position sensorless inverter in the case of 120 degree energization.

摘要： A motor having a lap winding structure and a manufacturing method therefor, wherein inserts of two different coils are installed side by side in one slot of a stator in a circumferential direction of the stator. All the coils are inserted in slots in succession. Further, a stator having semi-closed type slots formed by protuberances oriented in different directions, is used to control a reduction in the magnetic flux at the inlet of a slot and also to prevent coils from coming off. In a motor having coils of a plurality of phases for generating a rotating magnetic field at a stator, the contact portion of the coil of the desired phase among the coils of the plurality of phases and a portion rising from a slot toward the axis of a core are aligned and disposed to have a shape which prevents them from interferring with end portions of the coils of other phases.
