Abstract: A stator and a rotary electric machine include a stator core including a plurality of stacked annular electromagnetic steel plates with coupling portions. The coupling portions are arranged with a pitch of an integral multiple of a central angle. The central angle is defined as an angle between two adjacent magnetic poles of the same polarity relative to a rotational center of the rotor. When a number of the coupling portions is an odd number, fixing portions are arranged with the same pitch as the pitch of the coupling portions, or with a pitch corresponding to a divisor of the pitch of the coupling portions. When a number of the coupling portions is an even number, the fixing portions are arranged with a pitch corresponding to a divisor of the pitch of the coupling portions, or a divisor of 180°.

Abstract: A method for manufacturing a rotary electric machine rotor includes forming core block elements; inserting magnets in corresponding one of the magnet holes; forming magnet core blocks by injecting a molten resin into each of the magnet holes from above the magnet, solidifying the molten resin, and thereby forming a resin portion so as to integrate each of the core block elements and the magnets. End surfaces of the magnets are exposed on a first end surface; and the molten resin is injected at a second end surface. The method also includes forming a rotor by stacking and integrating plural magnet core blocks, the plural magnet core blocks being stacked such that first end surfaces of two magnet core blocks that are disposed at both ends in an axial direction constitute end surfaces at both ends of the rotor in the axial direction.

Abstract: A rotary electric machine equipped with a magnetic flux variable mechanism includes a case body, a mover moving upon receipt of centrifugal force, a magnetic flux short circuit member, a cam member, and biasing springs. The cam member includes a cam surface so as to face the mover and make contact with the mover, and the cam member converts a radial movement of the mover received by the cam surface into an axial movement of the magnetic flux short circuit member. The biasing springs give a biasing force to the magnetic flux short circuit member in a direction distanced from an axial end surface of the rotor core, so as to determine a position of the magnetic flux short circuit member along the axial direction in a state where the biasing force is balanced with the centrifugal force applied to the mover via the cam member.

Abstract: A rotary electric machine stator includes a stator core, a multi-layer winding coil, a first insulating resin layer, and a second insulating resin layer. The multi-layer winding coil is arranged with a predetermined number of steps in the radial direction of the teeth. Each step of the multi-layer winding coil includes a lowest layer coil of one winding and a surface layer coil of another winding. The first insulating resin layer is arranged between the teeth and the lowest layer coil, or between an insulator that is fixed to the teeth and the lowest layer coil. The second insulating resin layer is arranged locally at curved portions of the multi-layer winding coil that correspond to corner portions of four corners of a rectangular cross-section of the teeth. The second insulating resin layer is arranged extending across a plurality of steps of the multi-layer winding coil.
