About
The Linear Drive is a high-precision electromechanical drive for linear positioning. Its primary purpose is to synchronize the force spoke motion or transfer during the deployment of an antenna. The device features two commutator electric motors, with one serving as a reserve for enhanced reliability. It operates within a wide temperature range of -50 to +70 °C and has an operational life of at least 100 cycles. The drive has an axial travel rate between 0.4 and 0.8 mm/s and can exert an axial shear force of 2000 N. It operates on a 27 V supply voltage with a maximum consumption current of 0.4 A for both motors. Its compact overall dimensions are 75 x 90 x 70 mm and it weighs 1.3 kg.
