FIELD: electrical machines feeding off-line navigation and geophysical instruments used in boring wells.
SUBSTANCE: proposed device has hollow packed and wound stator accommodating bearings-mounted rotor shielded at stator outlet with spring-loaded sliding end packing whose casing is provided with loosening drilling accommodating shaped flexible gasket. Spring-loaded end seal is built of two separate functionally identical parts whose bodies abut against one another through their edges and are isolated by additional packing members. One part of spring-loaded end seal mounted on coupling bushing installed on rotor shaft in a spaced relation is free to move in axial direction and loosening drilling of this part, as well as its body form together additional collar responding to pressure within borehole instrument.
EFFECT: enlarged service life of borehole instruments.
