Abstract

960,924. Cooling dynamo-electric machine coils. ASSOCIATED ELECTRICAL INDUS. TRIES Ltd. Sept. 28, 1962 [Dec. 1, 1961], No. 43058/61. Heading H2A. In a dynamo-electric machine rotor having a winding comprising a plurality of coils each comprising two coil sides in respective slots spaced apart and each side comprising a plurality of conductors 4 having longitudinal coolant passages 3 and being so transposed that each in turn has a portion radially inside the other conductors, there is provided a longitudinal duct 1 lying radially inside each slot, forming a conductor of the coil, and having its coolant passage connected by electrically insulated liquid connectors 2 to those passages 3 of the conductors 4 in the associated slot at the points where the conductors are radially innermost in the slot. The transposition shown is of the " Roebel type, and the liquid is water. Specification 903,396 is referred to.
