Abstract: Provided is a magnet that allows the orientation direction of main and auxiliary pole pieces to be set precisely and enables easy fabrication of flux focusing permanent magnet units having a high magnetic flux density A magnet 22 includes permanent magnet units 22a each including a main pole piece 221 and auxiliary pole pieces 222. The main pole piece 221 is composed of permanent magnet sheets 221a with substantially the same thickness stacked in the thickness direction. The auxiliary pole pieces 222 are composed of permanent magnet sheets 222a with substantially the same thickness stacked in the thickness direction and arranged at positions adjacent to the main pole piece 221 with orientation directions different from the orientation direction of the main pole piece 221 thereby to focus the magnetic flux at the main pole piece 221.

Abstract: A rotating electric machine 100 having a rotor 1, a stator 2, and a coil 3 including a coil conductor 31 wound around teeth 21b provided on at least one of the rotor 1 and the stator 2 includes a spacer section 42 configured to extend along a slot S formed between the teeth 21b and to be inserted between turns of the coil conductor 31 to define a gap G between the turns, and a cooling medium supply section 6 configured to distribute a cooling medium in the gap G. A notched section 421 cut out in such a manner that a widthwise dimension of the spacer section 42 is relatively short is provided in a middle of an extension of the spacer section 42.
