1506289 Windings in electrical machines PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 May 1975 [27 May 1974] 22663/75 Heading H2A A machine has a stator with a smooth inner surface and coils which lie at least partly in the rotor/stator air gap; the aggregate radial dimension of the coils of each phase remains constant through successive angles of 90/n electrical degrees, where n=2, 3, 4 etc.; and this aggregated dimension changes from an initial maximum value nx to a minimum value x in equal steps and then changes from an initial minimum value x to a maximum value nx in further equal steps. In the arrangement shown, coils 1, 2 of one phase are nested with coils 3, 4 of a second phase to produce a winding of uniform thickness. |
