Abstract
1449964 Dynamo-electric machines T SABEV 4 Feb 1974 [5 Feb 1973] 05086/74 Heading H2A A laminated cage rotor for an induction machine has an incision 3 between each pair of adjacent slots, the incision being enclosed or open to the rotor periphery, extending lengthwise of the rotor, extending radially inwards to at least half the depth of the slots and containing at least one elongate, electrically conductive member 4 not forming part of the cage winding and/or a heat-resistant elongate member of electrically insulating material. Electrically conductive members 4 may be of copper or of ferro-magnetic material. The constructions disclosed are stated to improve the torque characteristics of squirrel cage rotors. Surface losses may be reduced by interposing insulating material between adjacent laminations at selected positions along the length of the rotor. The following abridgment is included in this series since the Specification was through an error, not allotted to this group. Reference to it will be found in the name index to this volume.
