Abstract

962,170. Casting composite articles. GENERAL ELECTRIC CO. Dec. 21, 1960 [Dec. 29, 1959], No. 43893/60. Heading B3F. [Also in Division H2] In a high-resistance squirrel cage rotor having cast conductor bars which zig-zag between positions 44, 48 adjacent the inner and outer peripheries of the rotor core, the necessary longitudinal rigidity to prevent separation of the laminations is achieved by axially staggering alternate bars round the rotor so that an outward portion 44 of one bar is adjacent inward portions 48 of bars on each side to produce a bonding or interlocking action. Thus for example the gap 60 is prevented from opening by sections 54 of adjacent conductors. The zig-zags are produced by the use of stacks of laminaµ with rings of mutually staggered slots near the outer periphery and near the shaft, spaced by stacks of laminµ having slots deep enough to link them. The lengths of the inner and outer portions of the winding need not be the same throughout the length of the rotor.
