Environmentally protected housingless generator/motor

摘要

A stator arrangement particularly suitable for use in an air-cooled generator or other such electric machine includes a stator with an outer stator surface, an opening therein defining an inner stator surface, and longitudinally opposed stator end surfaces. Conductive coils are supported by the stator, and include end turns overlying the longitudinally opposed stator end surfaces. In order to block out environmental contaminants and prevent conductive coil shorting, protective barriers are mounted over the end turns and secured to the stator.

1. A stator arrangement for an air-cooled electric machine, comprising:
a stator with an outer stator surface, an opening therein defining an inner stator surface, and longitudinally opposed stator end surfaces, an adhesive that impregnates the stator and seals the outer and inner stator surfaces, conductive coils supported by the stator, the conductive coils including end turns overlying the longitudinally opposed stator end surfaces, protective barriers that are mounted over the end turns and that are secured to the adhesive impregnated stator to block out environmental contaminants and prevent conductive coil shorting, the protective barriers each including inner and outer sides, surrounding a conductive coil end turn receiving volume, and a flange, extending radially outward from the outer side, defining an outermost circumferential protective barrier edge, and a bead of sealant placed over each interface between the stator and the outermost circumferential edges defined by the flanges of the protective barriers.
