Kearfott designs and produces an array of electric motors for use in the aerospace, defense and critical applications. Kearfott specializes in high performance permanent magnet (PM) and induction motors, our PM motors employ rare-earth permanent magnet materials and high-performance magnetic alloys. Kearfott engineering’s optimized design techniques provide high power density while maintaining very competitive cost.

Kearfott also produces instrument grade induction and synchronous motors as well as VR and hybrid step motors.

Kearfott’s motor offerings include:
- Brush DC
- Brushless DC
- Brushless pancake torquers
- Induction
- Reluctance
- Synchronous
- Stepper

Custom designs are available to meet the most challenging application requirements.

Available in three compact versions:
MINS - Mini INS with Nav software enabled IMU
NxNAV - NxINS/GPS System
NxMAX - Expandable NxINS/GPS System

The NxNAV™ consists of a monolithic ring laser gyro with a tightly coupled INS/GPS, a 24-channel SAASM (with growth to M-Code) GPS receiver, and a civil multi-constellation GNSS receiver. It meets the environmental requirements of MIL-STD-810-G/DO-160, with no forced-air cooling required.

NxNAV™ meets DO-178C Level A and DO-254 Level A to support Technical Standard Order, Military Standard Order, and/or service airworthiness certification.

Kearfott’s Next-Generation Inertial Measurement Units (NxIMU) incorporate the most advanced sensor technology and innovative packaging for industry-leading size, weight, power, and performance—addressing the navigation needs for a variety of sea, land, air, and space market segment applications. These monolithic ring laser gyro (MRLG) NxIMUs are ideally suited for applications requiring high performance for navigation, line-of-sight stabilization, and flight control in a compact form factor. The NxIMUs are offered in two performance grades: navigational or tactical.

The NxIMUs consist of Kearfott’s patented three-axis MRLG, three Kearfott force-rebalanced pendulous accelerometers, and electronics in environmentally sealed housing. Utilizing MRLG reduces the number of piece parts, weight, and volume compared to a system using three single-axis gyros. These NxIMUs meet FAA DO-178C Level A and DO-254 Level A, as well as military standards and/or service airworthiness certification.

With expertise in high-precision design and manufacturing, Kearfott delivers reliable components—IMUs, EM actuators, motors, and position sensors—for mission-critical aerospace systems. Our solutions support missile fin actuation, thrust vector control, guidance and navigation, seeker stabilization, GPS anti-jam/anti-spoof, and visual navigation technologies, with a proven track record supporting a long-standing, widely deployed anti-ship missile program since the 1970s.

Kearfott custom designs its proven modules into unique packages for both discrete actuator applications and complete integrated tail kit solutions that typically include all axis and fin lock control.

Built on Kearfott’s extensive expertise in designing and manufacturing advanced position sensors and controls for aerospace and defense applications, the CSA delivers unmatched performance and reliability.

CSA Benefits:
• Low cost
• Lightweight
• Highly reliable
• Proven Kearfott position sensors
• Adaptable design for any interface
Precision and Performance
Each Kearfott CSA offers integrated damping, centering feel force, and position feedback, enabling pilots to execute precise pitch-and-roll commands intuitively.

Optimized Position Feedback
The CSA features 6 channels (3 per axis) of high-performance Kearfott Variable Differential Transformer (VDT) position sensors. Rotary or Linear sensors (RVDTs and LVDTs) are selected based on system requirements. Sensors are integrated with channel-to-channel separation to provide the highest level of redundancy. Additionally, alternate position feedback options and adjustable channel counts are available to meet specific system requirements.

Pilot-Preferred Centering Feel Force
Kearfott engineers collaborate closely with pilots to optimize the variable force profile for each application. The cam-based centering mechanism, with adjustable gradients depending on deflection direction, offers limitless profiles. It ensures a low-backlash solution, independent centering for each axis, and a flexible design that accommodates diverse human factors.

Ultimate Flexibility
Kearfott gives you the flexibility to integrate your own grip or choose a complete solution with a custom grip design tailored to your needs. The Kearfott CSA is a cost-effective, lightweight, and highly reliable, passive solution for both military and commercial fly-by-wire aircraft.

Kearfott resolvers continue to lead the sensing industry in quality, reliability, and functionality. Innovative design solutions allow for small, lightweight sensors that can perform over a wide array of operating conditions. Applications for Kearfott resolvers span the aerospace industry, including high-speed motor commutation,
control surface feedback, pilot command/feedback, fuel controls, and stabilized platforms.

Kearfott offers single-channel, multi-channel, and pancake configurations as well as fully integrated gearhead resolvers with customizable gear ratios.

The Kearfott K2000 family of actuators is ideal for primary and secondary unmanned aerial vehicle (UAV) flight control, landing gear, and utility applications. Our UAV actuator solutions are easily adaptable and deliver
superior performance in the smallest of envelopes.

The renowned Kearfott K2000 actuator has accumulated over one million flight hours; many in extreme military environments. Its unique, low-profile design is powerful, lightweight, and well suited to today’s thin-wing section and volume constrained requirements. Our full line of actuators also includes the higher power K3000; introduced to meet the flight control demands of high-performance UAVS.
