Abstract

955,991. Dynamo - electric machines. ENGLISH ELECTRIC CO. Ltd. Sept. 12, 1960 [Sept. 18, 1959], No. 31860/59. Heading H2A. Commutator segments 1, 3, 5, 7... in a lap-wound armature are separated by auxiliary segments 2, 4, 6 ... maintained at intermediate potentials by a common ring resistor or transformer potential divider. The auxiliary segments are narrower than the main segments and may be at a lower level to avoid contact with the brushes. In a modification (Figs. 2 and 3, not shown), the auxiliary segments are replaced by one or more copper foils separated by mica sheets and connected to appropriate tappings on the divider. In the case of multipolar machines, a single divider connected to equalizers may be used (Fig. 4, not shown). The resistive divider may be wound on an insulating ring behind the risers.
