Abstract

778,138. Cooling conductors of dynamo-electric machines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 2, 1955 [Nov. 2, 1954], No. 31697/54. Class 35. Bar conductors of turbo-alternator rotors have elongated longitudinally extending slots in the end winding portions so that when radially superimposed they provide radial cooling passages, a port or ports between each of said passages and a side face or faces of the coil being provided by cutting away the conductor straps. As shown, the top conductor 1 in each stack is unslotted in any way but the next bar has notches in its sides 10, 11 to enable air which has flown radially through the passages provided by slots 9 to flow to the sides of the stacks into radial and transverse grooves 19 in the sides of spacers 12 (not shown in Fig. 1) which occupy all the spaces between the end winding stacks, and having reached the innermost spacing block the air passes into axial ducts 4 in the teeth. The slot conductors are cooled by air which traverses axial sub slots 24 and then passes radially through the conductors and leaves by holes 26 through the slot wedges. Additional notches 10, 11 can be provided in bars at intermediate levels, and preferably are staggered along the end winding portions.
