Abstract

647,575. Dynamo electric machines. ENGLISH ELECTRIC CO., Ltd. Aug. 26, 1948, No. 22486. [Class 35] [Also in Group XXII] Radial air gaps 8 of a width appreciably less than 0.05 inch are formed between the inner and outer winding slots 2, 3 of laminations 1 for squirrel cage rotors by combined shearing and punching or bending operations. The invention is also applicable to bar-wound and die-cast rotors.
