FIELD: machine building.
SUBSTANCE: invention relates to electric drives and can be used in pipeline valves and accessories. Proposed drive comprises the body. Motor and manual back-up shafts are mounted perpendicular to each other. Gear wheels are rigidly fitted on aforesaid shafts. Gearshift mechanism shits aforesaid gear wheels from electric control to manual one. Motor shaft is linked up with reduction gear input shaft. Gearshift mechanism represents an eccentric bushing. Manual back-up shaft is fitted inside the body with the help of eccentric bushing furnished with a lever for it to be turned in the housing.
EFFECT: higher reliability, simpler design and operation.
