Advanced Actuator Technology
Tesar Drive™ is a proprietary geartrain technology to enable the next generation of electromechanical actuators (EMAs) with unparalleled torque and precision. Tesar Drive™ is the culmination of over 20 years of invention and seven fully awarded U.S. Patents.
Benefits of Tesar Drive™
Tesar Drive™ combines a patented geartrain configuration and novel tooth geometry to provide numerous advantages over traditional electro-mechanical actuators (EMAs).
Higher Torque Density
Tesar Drive™ enables extremely high ratios—250:1 or greater—in a single reduction stage to enable world-leading torque density. As a result, Tesar Drive™ can produce significantly more torque within a given volume than anything else on the market.
Higher Load Capacity
The Tesar Drive™ design includes multiple tooth contacts and optimized force paths to handle loads far greater than status quo EMAs.
Precision Control
Tesar Drive™ actuators have near-zero backlash under all load conditions enabling new standards for precision control.
What Can Tesar Drive™ Do for You
Hydraulic Actuator Replacement
Tesar Drive™ combines the power output of hydraulic actuators with the benefits of EMAs—truly the best of both worlds. Replacing hydraulic actuators with Tesar Drive™ actuators provides superior performance while reducing volume, weight, maintenance, and system complexity.
High Load Precision Control
Tesar Drive™ enables a novel class of EMAs that can handle hydraulic loads with unparalleled control and precision―opening up a range of actuator applications never before possible. What will you build with Tesar Drive™?

When Can I Get Tesar Drive™
The first Tesar Drive™ prototype was successfully manufactured, assembled and load tested as a direct replacement for a hydraulic piston. The prototype is ultimately intended to replace hydraulic actuators for jet blast deflectors on U.S. Navy carriers. Additional defense prototypes will kick off in 2026.
