Positioners
Atlantic's product line consists of the SPS-500, SPS-1000, SPS-2000, SPS-4000 and SPS-6000 series positioners, which vary primarily in size and torque capability. The design and construction techniques are largely similar and constitute a rugged COTS design suitable for land, marine, and airborne gimbal applications.
Some of the key features found in each positioner series includes direct drive brushless motor and resolvers to achieve a virtually no-wear design configuration resulting in a high reliability, quiet/low noise operation and low life cycle cost product. The only wear item, the bearings, are dual pre-loaded angular contact bearings designed to last the life of the product.
The modular construction allows Atlantic to configure the positioners for a variety of payloads including variable width yoke configurations and T-Bar designs, special configurations, and 3-axis gimbal systems.
The resulting designs are sufficiently flexible to allow the systems to be tailored for high dynamics applications (over 1200°/sec and 1200°/sec2 have been achieved), high stiffness for wide rate and positioner loop bandwidths, and allows adaptation of a wide variety of payload configurations with through pedestal cabling for remote control of the payload sensors.
Other features of the SPS product line include all aluminum construction to achieve a lightweight yet stiff product, the mechanical pieces are anodized and painted with a rugged, weather resistant powder coat epoxy paint, the hardware, except in high load bearing areas, are stainless steel, and all steel parts, including hardware, are nickel plated. The positioner's standard features include cushioned end stops, mechanical stow locks, cable wrap, software settable limit switches, safety switch and MS connectors. The design, including the bearings, is designed for a minimum 20-year life.
