Abstract

725,249. Squirrel cage constructions. GENERAL MOTORS CORPORATION. Aug. 6, 1953 [Aug. 16, 1952], No. 21689/53. Class 35. [Also in Group XXII] In a rotor for an electrical machine comprising a pack of laminµ 21 held between a pair of conductor rings 35, 40 interconnected by conductor bars B passing through perforations in the laminµ, the rings and bars are unitary and are die cast in position, and the rings are of substantially semi-circular crosssection.
