Abstract
1439262 Squirrel cage rotors WAGNER ELECTRIC CORP 16 Nov 1973 [22 Nov 1972 53285/73 Heading H2A A squirrel cage rotor, having a cast cage constituted by a pair of end rings 22, 23 and a set of conductor bars in radially outer slots 6 of the rotor core laminations 1, has strengthening bars cast in radially inner slots 7 of the laminations 1 at the time of casting of the squirrel cage, the strengthening bars being formed so that one set of axial ends 30 are integral with the end ring 22 whilst the other set of axial ends 31 are separated from the corresponding ring 23; the strengthening bars are therefore unable to conduct currents and do not soften through heating. The conductive bars and the strengthening bars are preferably skewed as indicated. The casting operation, described with reference to Fig. 2 (not shown), simultaneously produces fan blades 27 and counter balance weights 28 on the rotor. A bore 5 is counterbored at 32 for a load shaft 33. A further counterbore (201, Fig. 6, not shown) may be formed if desired.
