FIELD: machine building.
SUBSTANCE: opening drive comprises a casing with a gear reducer and an electric motor installed in the casing. Two commutator DC electric motors determining the drive rotation or braking speed are used as the electric motor. Inertia clutches are included in the kinematical chain of each electric motor, and the reduction ratio of the reducer part before the inertia clutches amounts to maximum 10000.
EFFECT: higher reliability of a device.
