    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: An apparatus for assembling a coil includes a blade inserted into a slot of a stator core in a state where insulating paper is inserted into the slot. In a method for assembling the coil, the insulating paper is inserted into the slot of the stator core, the blade is inserted into the slot into which the insulating paper is inserted, the coil is inserted into the slot into which the blade is inserted, the coil being inserted in a direction opposite to a direction in which the blade is inserted. When the coil is inserted into the slot, the blade is pulled out from the slot along with the insertion of the coil into the slot.

    Abstract: A rotor for a rotating electric machine includes: a rotor core having magnet holes; magnets inserted in the magnet holes of the rotor core. Each of the magnets includes two first surfaces respectively facing outward and inward of the rotor radial direction, and two second surfaces respectively facing one side and the other side of the rotor circumferential direction. Both ends in the rotor axial direction of at least one first surface of the two first surfaces are covered with electric insulating films, and a lateral surface region between both ends of the one first surface that are covered with the electric insulating films, and the two second surfaces are covered with no electric insulating films.
