    摘要： It is aimed to provide a field element capable of easily measuring an air gap between magnetic poles while making a waveform of a magnetic flux density close to a sinusoidal wave. A field element core (1) has a perimeter (10) exposed around a rotation axis (P) and a plurality of field magnet insertion holes (30) circularly disposed around the rotation axis P. A radius (R) between the perimeter (10) and the rotation axis P decreases in a monotonically non-increasing manner from a pole center (101) toward an interpole (102) and then increases in a monotonically non-decreasing manner in a region between the pole center (101) and the interpole (102) in a circumferential direction (D).

    摘要： A rotor (20) includes a core (21) having a through hole group (100) including three or more through holes (25) arranged in a circumferential direction. The through hole group (100) is formed through a predetermined magnetic pole. The core (21) includes two or more ribs (24) each interposed between associated adjacent ones of the through holes (25). One of the two or more ribs (24) that has a relatively small inclination (θ) with respect to a magnetic pole centerline (MC) is narrower than another one of the ribs (24) that has a relatively large inclination (θ) with respect to the magnetic pole centerline (MC). The magnetic pole centerline (MC) is a straight line that passes through a radial center line of the predetermined magnetic pole and an axial center (O) of the rotor (20). As a result, the dimensions of the ribs of the rotor can be optimized.

    摘要： A stator core (21) including field slots (213a) housing field windings (23) and armature slots (213b) housing armature windings (24) is provided. Permanent magnets (22) are housed in the respective armature slots (213a). The armature windings (24) are configured by a first winding (24a) and at least one second winding (24b, 24c). The field winding (24a) passes over the permanent magnet (22). The second windings (24b, 24c) each have a part embedded between a coil end (23a) of the field winding (23) and teeth (211) around which the field winding (23) is around.
