Abstract

1472773 Winding layouts in dynamo-electric machines NATIONAL RESEARCH DEVELOPMENT CORP 30 May 1975 [12 June 1974] 26040/74 Heading H2A A 3 phase PAM electric machine has phase windings ABC comprising two parts, e.g. 1 and 2 for phase A, connected respectively in series and parallel for two different pole numbers, each phase winding including at least one pair of additional coils, e.g. 5 and 23, Fig. 7 for phase A, which are omitted for one pole number, the two coils of each omitted pair in each phase winding occupying the same slot vector angular positions, Fig. 6, and omitted coil pairs in different phase windings occupying corresponding slot vector angular positions in their respective phase vector groups. This arrangement is said to give an air gap flux density ratio, for the different pole numbers, which is close to unity. The winding shown in Figs. 6 and 7 is a 6 pole (8 pole winding in 36 slots, terminals A1, B1, C1 being energized and terminals A2, B2, C2 being short-circuited for 6 pole operation). For 8 pole operation, terminals A2, B2, C2 are energized, terminals A1, B1 C1 being opencircuited and coils 5, 23, 17, 35 and 2, 20 being therefore omitted. Figures 3, 4 (both not shown) illustrate a 6 pole/8 pole winding in 108 slots in which two pairs of coils are omitted from each phase winding for 8 pole operation. (For Figures see next page.)
