1.6 Description of the Actuator
The actuators MP 52 200 (Fig. 1) consist of the following modules:
Module М 1 – an electric motor
Module M11 – a countershaft box
Module
М 3 – a gearbox with a manual control mechanism
Module М 4 – a control box
Module M6 – a linear adapter

Module М 1 – an electric motor
One-phase asynchronous electric motor (Fig. 1)
Module М 11 – a countershaft box
It provides reduction of output speed of the electrical motor to a given gear value. The
countershaft box consist of six pairs of meshing helical gear wheels and it is ended with a conical
pinion meshing a conical wheel of a power gear of the module M3.
Module M3 – a gearbox with a manual control mechanism
The gear train is located in the case (1). The gears are placed on the output shaft (3) and they
make up an independent assembly set. The rim (44) with internal teeth provides gearing between the
pinion of the electrical motor and the output shaft. The worm (2)designed for torque taking down and
manual control is seated in the upper part. The resetting is made with the handwheel (4). The worm is
then sprung and the power caused by torque of the output moves the worm shaft axially against spring
power. The movement of the worm is taking off by a fork and a pin through shafts (45) leading to the
control box. The movement of the worm is measure of the torque. The fork meshes with the groove
circumference to allow rotary movement of handwheel it means its rotary movement in every position.
