摘要： A rotary electrical device includes a rotor having a substantially hollow cylindrical shape or a substantially solid cylindrical shape and configured to be rotatable; and a stator having a substantially annular shape and disposed in a radial direction of the rotor to surround a rotation axis of the rotor. The stator includes a plurality of stator units that are stacked in an axial direction of the rotor. Each of the stator units includes a winding that is wound in a substantially annular shape around the rotation axis, a stator core that surrounds the winding, and one or more claw magnetic poles that protrude radially toward the rotor from each of two end portions in an axial direction of the stator core. The rotor includes a magnet that radially faces at least a portion of any of claw magnetic poles of the stator at a predetermined rotation position. At least one of magnet end portions in an axial direction of the magnet protrudes further in the axial direction than all of the claw magnetic poles of the stator.

摘要： The present invention relates to an armature core (10) formed by laminating a plurality of magnetic plates (12) punched into a predetermined shape, which includes a prism portion (14) around which an armature coil (30) is wound and a first rectangular solid portion (16) buried in a recessed portion (22) of a yoke (20). A shape in cross section of the prism portion (14) is formed to have a substantially trapezoidal shape on a surface with a rotation axis (Q) being a normal, whereas a shape in cross section of the first rectangular solid portion (16) is formed to have a substantially rectangular shape on the surface. In punching the magnetic plates (12), a punching step for a part constituting the prism portion (14) and a punching step for a part constituting the first rectangular solid portion (16) perform separately. In the vicinity of a boundary between both parts, regions capable of being punched with molds that are used for the punching steps are caused to overlap each other by a predetermined width, to thereby avoid stress concentration on a boundary region.

摘要： An object of the present invention is to prevent an increase in the number of back yokes in which an alternating magnetic flux is generated while reducing a thrust force by providing stators on both sides along a rotation axis of a rotor. An axial gap rotary electric machine includes a rotor (1), an armature (2) and a stator (3). The rotor (1) is a magnetic body, which is capable of rotating in a circumferential direction about a rotation axis (Q). The armature (2) includes an armature coil (22) opposed to the rotor from one side in a rotation axis direction parallel to the rotation axis. The stator (3) causes the armature coil to interlink with a magnetic field flux from the other side in the rotation axis direction via the rotor.
