The housing for rotating electrical machines of the type open proof drops

摘要

The present patent of the invention relates to a casting for electrical rotating machines, preferably for open drip-proof machines type, granted by a greatest number of contact elements between the casting and the stator, these elements being fins with different lengths, arranged in its interior, so that to increase the heat exchange efficiency between the assembly stator/casting and the cooling fluid, maintaining an uniform temperature distribution along the length of the stator and coils.
