Abstract

338,135. British Thomson-Houston Co., Ltd., and Martin, E. H. B. Aug. 9,1929. Maintaining equal speed.-The secondaries of two induction motors 1 and 2, shown in the Figure and intended to run in synchronism, are coupled together by inductance windings 3, 4, 5, the midpoints of which are tapped and brought out to a common variable resistance 6. The stator windings are supplied from a common source 7. Specification 8748/15 is referred to.
