In this paper the impact of different end region cooling arrangements on the endwinding heat transfer is analyzed. An experimental approach to the problem solving has been adopted: two ??ad hoc?? prototypes have been built, and a test bench has been assembled. Open drip proof ??ODP?? and total enclosed fan cooled ??TEFC?? frames have been taken into account. In addition the cooling effect of the fins...
This paper deals with the endwinding cooling problems of totally enclosed fan-cooled (TEFC) induction motors. In order to obtain information about the phenomena involved in the motor end space, three "ad hoc" prototypes have been built. The complete test-bench setup, together with the followed test procedures, is reported in detail. The measurement results have shown that all the motor-part...
