Beschreibung
Zusammenfassung:	FIELD: electrical engineering; power supplied to borehole loads. ^ SUBSTANCE: proposed generator is characterized in that radial-axial bearing disposed at end of post on one end of stator is built of two bearings, one axial and one radial bearings, with flexible member inserted between part of frame and outer ring of one of these bearings, that additional radial bearing is installed on post at other end of stator, stuffing assembly of stator frame is disposed between end section of its movable part and post, and that it has end seal, annular cavity with radial-end collar and lubricant, as well as impeller, all mounted in tandem from additional bearing on butt-end of frame movable part. ^ EFFECT: enhanced reliability of generator protection against external adverse impacts. ^ 1 cl, 2 dwg
