Precision Motion When it Counts

For over 40 years, Copley Controls has designed and delivered high-performance motion control solutions for the defense sector. Our servo drives play a critical role in military vehicles, aircraft and naval systems, precisely controlling rotary and linear motors in these mission-critical applications.

Ruggedized to Meet MIL-SPEC Requirements

Designed for harsh operational conditions, our ruggedized drives deliver reliable performance when failure is not an option:

Temperature extremes: -40°C to 70°C
Thermal shock: -40°C to 70°C in 1 minute
High humidity: 95% non-condensing  at 60°C
Vibration: 5 Hz to 500 Hz, up to 3.85 grms
Shock: 40 g peak acceleration
Extreme altitudes: -400 m to 16,000 m

We also design and test all our systems to meet stringent military standards, including:

MIL-STD-810: Environmental Engineering Considerations
MIL-STD-1275: Electrical Systems in Military Vehicles
MIL-STD-704: Aircraft Electric Power Characteristics
MIL-STD-461: Control of Electromagnetic Interference
MIL-STD-1399: Interface Standard for Shipboard Systems

Additional standards and certifications include ISO 9001:2015, RoHS compliance, UL/IEC 61010-1, 61800-5-1 and 61800-5-2.

Advanced Features and Flexibility

To meet the evolving needs of the defense industry, our drives incorporate advanced features like 32-bit floating-point multi-loop filters, frequency analysis tools and high-speed position capture, enabling precise control and monitoring of motion systems. Drives — like our R-Series — also support multiple command interfaces, including CANopen, EtherCAT, RS-232/422, analog commands and step/direction signals for seamless integration into legacy and modern systems. For greater installation flexibility, our drives are available in high power density panel-mount and PCB mount packages, with a complete set of feedback options.

Software Support

We offer powerful, intuitive software tools designed to streamline the integration of our drives into complex systems and reduce development time. Our Copley Motion Explorer software provides comprehensive diagnostics and auto-tuning, plus distributed control software for CANopen with C++ libraries and .NET framework objects.

Drive Applications

Military Vehicles. Our drives provide precise motion control in armored vehicles and specialized military equipment, withstanding extreme vibration and shock.
Aircraft Systems. Whether flight control, weapons systems or UAVs, our drives deliver reliable performance and precision in aerospace environments with strict power, EMI and weight requirements.
