The Curtiss-Wright NC120A is a rugged, compact servo controller that delivers over 3 kW of output power and has the power to manage the actions of a wide variety of components in precision drive systems, including motors and motor feedback types, gyroscopes, and hand controllers, in a compact package weighing just over 4 pounds.
Accelerate time to market with pre-designed motor drivers
Pre-designed motion controllers based on COTS components address all the key challenges faced by system integrators when developing a controller. Furthermore, by leveraging Curtiss-Wright’s long history of providing modular and fully customized motion control and stabilization solutions, system integrators can significantly reduce the time required for development and qualification.
The NC120A has been designed from the ground up to maximize performance without compromising any other aspect of the controller’s design or operation. This model, which has undergone extensive testing to ensure that all components work together properly and comply with essential standards, can eliminate the long delays that occur with repetitive cycles of testing, redesign, and retesting according to multiple criteria.
Combines speed and power in a SWaP-compatible package
The Curtiss-Wright NC120A nano controller generates 120 A of maximum current with 28 V input power to deliver over 3 kW of output power in a compact package weighing just over 1.9 kg. It manages the actions of a wide range of system components, including motors and motor feedback types, gyroscopes, and manual controllers, without sacrificing valuable space. In addition, the NC120A includes high-speed processors and FPGAs to meet the most demanding motor control performance requirements.
Scalable solution to support any application
The modular architecture of the NC120A allows for quick and easy adaptation to meet the needs of any platform and application requirement, including modular control loop configurations for position, speed, and current.
For applications requiring maximum power in short bursts, such as remote weapon stations with small-caliber turrets, automatic loaders, or camera cranes, a low-power variant of the NC120A is available. On the other hand, the high-voltage variant provides up to 18 kW of maximum power output in short bursts and is ideal for guided weapon control systems equipped with a high-voltage power supply. This could include remote weapon stations with medium-caliber turrets or automatic loaders for larger-caliber weapon systems, up to 57 mm.
Robust design that complies with major military and safety standards
All components of the NC120A have been designed and tested to withstand the most demanding environmental requirements and are focused on maximizing mission lifetime. The nanocontroller includes an emergency stop and other functional safety measures that comply with IEC 61800 SIL and IEC 61508 SIL 2 standards to increase operational safety. In addition, the NC120A complies with established military standards, including MIL-STD-1275, MIL-STD-461, and MIL-STD-810.
