Abstract: Disclosed are: preparing a rotor core having a plurality of magnet holes spaced near a circumferential edge of the rotor core; preparing a plurality of permanent magnet units each including a porous body and a magnet main body disposed in contact with each other; and inserting the permanent magnet units into the magnet holes and securing the permanent magnet units in the magnet holes.

Abstract: A rotary electric machine includes a stator core having a plurality of teeth arranged in a row along a circumferential direction of the stator core, and a stator coil composed of a winding wire wound around the teeth. The stator coil includes coil end portions extending, outside the stator core in an axial direction thereof, along a substantially circumferential direction of the stator core, and straight portions extending along the axial direction, the straight portions being at least partially housed in a slot which is a void defined by two adjacent teeth of the plurality of teeth. In the rotary electric machine, a cooling groove is formed at least in the straight portion, the cooling groove functioning as a cooling channel through which a cooling fluid flows, and each straight portion includes only one cooling channel.
