Abstract

A totally enclosed motor comprising a housing totally encloses an electrical package that includes plurality of slot vents extending radially outward from a shaft on which the electrical package is mounted. The electrical package being operable to generate a closed circuit electrical package cooling air flow that circulates through the slot vents and is confined within the housing. The motor additionally including an exterior cooling assembly that is operable to generate a directed exterior air flow along an exterior portion of the housing. The motor further including a plurality of heat pipes having evaporator ends disposed within the closed circuit electrical package cooling air flow and condenser ends disposed within the exterior air flow, whereby heat is removed from the electrical package chamber such that the ‘Totally Enclosed’ more provides a power output substantially equivalent to that of an ‘Open’ motor of approximately the same size.
