Electromechanical Actuators

AMETEK Airtechnology Group is renowned for producing high performance, highly reliable wound electrical products. We've been designing and manufacturing electric motion control products for the Aerospace & Defense industry for almost 100 years our products include motors and rotary angular position sensors such as resolvers, RVDTs, synchros, and encoders.

Over the last decade, demand for electromechanical actuators (EMAs) has soared, driven by evolutionary changes in the transport industry and the development of electric vehicles. Today, we use our vast experience at a subcomponent level to transform our motors and sensors into complex assemblies that produce some of the world's most advanced electromechanical actuator designs helping modernise vehicles through reliable, easy-to-install, low-weight, low-maintenance alternatives to traditional control systems.

What Makes Our Actuators Different?

Our expertise begins in an actuator's heart its motor. Our team skillfully winds copper wire in the core (or stator), and deliberately doesn't use automated winding facilities: we believe the best way to achieve the performance our customers demand is by manually packing as much copper into a space as possible. The skills to hand-load a motor core take months of training and the utmost precision, dexterity, and technique the result is a motor that produces optimum performance from a very small package, and having these manufacturing skills in-house gives our designers a high degree of freedom when designing a new solution.

Just as copper core density matters to motor performance, how we protect the windings is critical to our products' ability to operate in extreme environments. With decades of experience protecting copper from corrosive and aggressive environments, we've developed techniques for encapsulating (impregnating) copper, using vacuum/pressure impregnation and various epoxy resin formulations to coat our windings. After this treatment, our copper windings can operate across a wide variety of applications and environments in the most extreme cases, submerged in hydraulic fluid, fuel, or water.

Design Integration and Knowhow

Our engineers have all the tools and experience in electromagnetic design and electromechanical integration to solve the most challenging requirements, including high-reliability, flight-critical applications. We also maintain close working relationships with our suppliers for key items such as ball screws, lead screws, roller screws, gearboxes, and LVDTs all critical to producing high-performance actuators.

An Experienced Team and Certified Products

We've produced several successful and unique designs, each pushing our technical abilities and the boundaries of actuator technology. Through customer projects, we've developed actuators that generate high forces, operate at temperature extremes, and actuate with high-speed response. They're subjected to high G-loads, carry multilevel redundancy, and can operate in concert with other actuators as part of a flight-critical system.
