Axial flux machine with single tooth fractional slot winding - Comparison of different winding design approaches

Non-overlapping concentrated windings in homopolar inductor machines

“…The description of this method can be also met in the following works, where it is used under the name of "star of slots" [1], [3], [5].…”

“…A number of works present a detailed description of the mentioned method, e.g. [1], [3], [5], [6]. The main idea of this method is in creation of sequence: of units (1) and zeros (0) from slots on pole and phase.…”

“…Concentrated coils are becoming popular for the use in synchronous machines with permanent magnets at present, which is proved by a large number of works developed in this area of science [1][2][3][4][5][6][7]. Scientific literature uses different terminology to identify this type of coils, namely, "concentrated winding", "tooth winding", "non-overlapping concentrated winding", "tooth concentrated", "fractional pitch winding" and others.…”
