Design of antenna mechanical scanning devices with low-power electric. Part 2

The aspects of mechanical devices design are discussed for scanning antenna with a low power electromechanical actuators which are based on flat crank, crank-rocker, rocker-crank, cam-rocker and other mechanisms. They allow back-rotation (scan) motion of the actuator drive. Peculiarities of created devices are considered which allow the optimal type choose and address their basic design.

It is Noted that the actuator that performs the scanning function could be much smaller if at the expense of management to ensure rapid and reliable reversal of the rotor of the electric motor during its operation.
