Abstract

458,381. Dynamo-electric machines. MOSSAY, P. A. H., and LAURENCE, SCOTT, & ELECTROMOTORS, Ltd., Gothic Works, Norwich. Sept. 24, 1935, No. 26473. [Class 35] Polepieces.-A polepiece for an alternator or a synchronous generator is formed of a pack of laminations attached by a dovetail joint to a steel plate, to which the laminations may also be welded. Fig. 4 shows a pack 1 of such laminations formed with a dovetail slot 2 in the underface, into which the steel plate 4 fits. The edges 3 of the slot 2 may be chamfered as shown to receive welding metal. The laminations are held together by copper rods 5 which, with copper laminations at the end of the pack, form a damping winding. Holes may be formed in the shoe to admit bolts for securing it to the shank, or screws may pass through the shank into the plate 4. The laminations may be further secured by pieces welded to the ends of the plate 4.
