System for servoing rotating actuators for a plurality of parts driven by a central box

摘要

Each rotary actuator (Ai) operates a lock (Si) with p stop positions, and is connected to a contactor (Ci) which supplies current till the required position is reached. Each contactor is connected to a central unit (1) by p supply lines (Li). Each actuator is linked to the central unit (1) by a second supply line (M), and data lines (Ii) which signal whether an actuator is supplied. A braking signal (Fi) is activated when the data line signals stopping of an actuator. Each actuator is a rotary motor which is braked by short circuiting the rotor.
