FIELD: electrics.
SUBSTANCE: invention can be applied as electric drive in submarines, bathyscaphes, electric vehicles, satellite systems and other devices requiring large power at small drive dimensions. Planetary electric motor reducer includes stator, along which satellite armature is rolled. Satellite armature features internal cavity housing output shaft and transmission gear in the form of gearbox or special inflated tyres with pressure built up by compressed air or fluid and adjustable by valve device. Satellite armature rotation eccentricity is adjusted by pressure in tyres and affects transmission ratio of friction couple of the device within wide range.
EFFECT: reduced drive dimensions and weight due to combined performance of several functions by single units.
