МВ3,5Д25Д

The rotary electromechanism МВ3,5Д25Д without limitation of output shaft rotation angle, two canals is intended for drive of flaps and stabilizer on aircraft Бе-200.

The electromechanism has built-in friction clutch, which is intended for protection of transmission and electric motors from overload, and built-in safe hand drive for system adjustment in ground conditions.

At de-energized state output shaft of the electromechanism is braked torque no less 54 N×m (5,5 kgf×m).

The electromechanism has small overall dimensions and mass, satisfies the contemporary requirements by external influence factors, technical standard and service life.
