Abstract

647,690. Dynamo - electric machines. SCAIFE, F. N., and BUCKINGHAM, J. Sept. 9, 1948, No. 23710. [Class 35] [Also in Group XXXVII] A polyphase commutator motor has a singlephase tapping on its rotor so that it may be switched from its normal motoring connection to operation as the receiver of a single-phase. Selsyn system for inching. In the " Auto " position of switch s both the stator windings 1, 2, 3 and the commutator brushes 5, 6, 7 are fed from a 3-phase supply for normal running. In the "Hand" position, the stator is connected to the stator of a hand driven Selsyn 11, whilst the rotor is fed through slip-rings and brushes 9, 10 from the single-phase supply, a transformer T and resistance R being inserted to limit the current.
