LINEAR MOVEMENT DRIVE Russian patent published in 1997 - IPC

FIELD: optical elements of tracing optical-electronic devices, elements of cellular main mirror of telescopes which are located on moving and stable beds. SUBSTANCE: device has serial circuit of digital-to-analog converter, power amplitude, and electric motor, which is connected to angular detector, adder, serial circuit of screw and end switch. In addition device has subtraction unit, which first input is connected to input for setting movement, predictor and generator of rectangular oscillations. Angular detector output is connected to second input of subtraction unit, which output is connected to first input of adder through predictor. Second input of adder is connected to output of generator of rectangular oscillations. Output of adder is connected to input of digital-to-analog converter. End switch is connected to input of power supply of electric motor. EFFECT: increased speed. 2 dwg
