Abstract
Totally enclosed motor for traction motors of the train and industrial motors can prevent intruding dust and extend the period of disassembly and cleaning. It is difficult to radiate the heat which generate inside the motor during operation. For further cooling performance improvement, the cooling structure by which inner air agitation and the outside ventilation are possible by using one fan was considered. Moreover, cooling performance was improved by the structure which cooling wind was inhaled in both sides of the motor and was exhausted at an iron core center. This paper describes the result evaluated by CFD about the coil temperature of the motor.
