Abstract

1471522 Winding layouts for dynamo-electric machines NATIONAL RESEARCH DEVEL. OPMENT CORP 3 April 1974 [13 April 1973 12 July 1973] 17943/73 and 33273/73 Heading H2A In a three phase machine utilizing pole amplitude modulation to switch from one speed to another, each phase comprises a number of coil groups spaced at substantially equal angles around the stator, the coil group distribution being approximately sinusoidal and the grouping is arranged such that for each phase a coil group occurs substantially at those points where the distribution curves crosses zero, there being no coils of the relevant phase at these points. Examples are shown of 8/10 pole machines wound in stators having 60 or 72 slots (Figs. 3, 6 not shown).
