Abstract

827,269. Making dynamo-electric machines. KETAY Ltd. Feb. 10, 1958 [May 13, 1957], No. 4298/58. Class 83 (2). [Also in Group XXXV] A squirrel-cage rotor is made by forming grooves 20 on the inner surface of a tube 22 of conducting material, e.g. aluminium, copper or brass, and inserting therein toothed laminations 10 mounted on an arbor 12, with a key 14 to ensure alignment. The tube is slightly longer than the stack of laminations and its ends are spun over to form end rings. The outer surface of the tube is then machined to expose the laminations, the lands 24 remaining to form rotor bars. The grooved tube may be extruded, or be a broached tube, and the grooves may be skewed.
