The drive ПP–172 is designed for control surface displacement according to the signals. It is a servo system with continuous control, which provides transformation of input electric signals to mechanical displacement of output components.
The Unit comprises the following blocks:
— DC contactless electric motor;
— power reducer;
— ball-screw transmission;
— drive reducer of ball position;
— braid with electrical connector.
Control Unit ПP-172 is designed for the following functions:
— interaction with control system;
— control of arresting of output components;
— realization of servo positioning;
— protection and control of the drive.
