Antenna positioning drives
Radar antenna systems can use separate azimuth and elevation axes. Each axis has its own mass distribution, inertia, operating range and environmental loads. The complete mechanism, bearing support, motor and control system must be considered together.
Selection considerations
- Define antenna mass, center of gravity, inertia and loads from wind and acceleration.
- Determine the output torque and speed over the full operating range, including holding and peak loads.
- Set the positioning accuracy, repeatability, allowable backlash and settling requirements for each axis.
- Check gearbox output bearing capacity, external supports, mounting and structural stiffness.
- Review temperature, enclosure, lubrication, duty cycle and braking or holding requirements for the installation.
- Confirm motor shaft dimensions, pilot, mounting pattern and the gearbox ratio against the drawings.
Information for selection
Provide the axis layout, mass and inertia, center of gravity, wind load, motion profile, accuracy requirements, environment and motor drawing. ANDANTEX can review the gearbox interface and operating requirements for the application.
