摘要： The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degrees from the output winding (1a), is continuously wound around all the slots over the output winding (1a). An output winding (1b) is continuously wound around all the slots over output winding 2. This equalizes the contribution of the output winding and output winding 2 to the flux linkage, thereby achieving high angle detection accuracy.

摘要： The N1(s) turns of a first output winding is divided by a split ratio α into N1a(s) turns of a lower-layer first output winding and N1b(s) of an upper-layer first output winding. The lower-layer first output winding is continuously wound around all slots as the undermost layer. A second output winding is continuously wound around all slots over the lower-layer first output winding. An upper-layer first output winding is continuously wound around all slots over the second output winding. The split ratio α is adjusted only in the slots where the detection accuracy decreases. This equalize the contribution of the first output windings and the second output winding to the flux linkage, thereby achieving high angle detection accuracy.

摘要： A plurality of stator teeth 2 are arranged at a constant interval in a circumferential direction on the inner circumferential face side or the outer circumferential face side of a ring-shaped stator core 1 that is made of a plurality of steel plates. The winding wire 5 is wound about the stator teeth. An insulator 4 that electrically insulates the stator core and the winding wire is provided therebetween. A gap 6 is formed between the winding wire and the insulator. Accordingly, a desired distance can be secured between the stator teeth and the winding wire regardless of the thickness of the insulator, and, thus, the influence of leakage magnetic fluxes that acts on the winding wire can be reduced. Accordingly, the influence of leakage magnetic fluxes formed near the stator teeth that acts on the winding wire can be reduced regardless of the thickness of the insulator.

摘要： A plurality of protruding portions each having a predetermined width in a circumferential direction are respectively provided at a predetermined interval along an outer periphery of a stator, and through-holes are formed at both ends in the circumferential direction of the protruding portions. A total length of the widths, which the protruding portions respectively have, in the circumferential direction is set equal to or less than 25% of an outer circumference of the stator. With this structure and by virtue of the through-holes, a compressive stress built up in an inner periphery of the stator due to pressing forces imposed on center areas of the protruding portions can be distribute toward the outer periphery of the stator.

摘要： A rotor (21) is an interior permanent magnet rotor formed of a rotor core (24) in which a plurality of permanent magnets (25) are embedded at predetermined intervals. First protruding portions (26) and second protruding portions (27) are formed on an outer peripheral face of the rotor, the first protruding portions (26) each opposing the vicinity of a central portion of each of the permanent magnets and having a substantially arc-shaped cross section protruding outward and the second protruding portions (27) each opposing the vicinity of an end portion of each of the permanent magnets and protruding outward. One first protruding portion and two second protruding portions correspond to one permanent magnet. The formation of the first and second protruding portions as described above on the outer peripheral face of the rotor makes it possible to sufficiently reduce the torque ripple and the noise caused by the distortion of air-gap magnetic flux distribution.
