Precision Electro-Mechanical Servo Actuators for Drones, UAVs, Unmanned Systems & Robotics

Volz Servos is a leading developer, manufacturer and supplier of standard, redundant and submersible actuators for a wide range of unmanned systems applications, including UAVs (unmanned aerial vehicles) and UAM (urban air mobility) platforms, UUVs (unmanned underwater vehicles), and ground robotics.

With over 40 years of industry experience, we deliver mission-critical solutions that meet the highest standards of functional safety and reliability and are perfectly tailored to the needs of OEMs, systems integrators, and aerospace primes. Our products are trusted by a wide range of industry leaders such as Thales, Zipline, BETA and Insitu.

Since the incorporation of AEE Aircraft Electronic Engineering GmbH, an EASA-approved production, maintenance and alternative development organization, our know-how has expanded to include a unique focus on certification in the UAV and AAM sectors. This makes it easier for Volz Servos to design customized, certifiable actuators that comply with both European and American aviation law.

Fully Redundant Actuators

Resilient UAV actuator solutions designed for reliability

DA 26-D Duplex Redundant Actuator

The DA 26-D  is designed for applications where reliability is of the utmost importance. Its two-channel redundant design means that it can continue to operate even after one channel has failed.

A three-channel position sensor is incorporated, as well as several diagnostic sensors that provide continuous information on current consumption, supply voltage levels and temperature readings. Data can be read out via the integrated serial RS-485 interface.

The DA 26-D provides a peak torque of 12 Nm with a 28V supply, and 4 Nm in degraded (1-channel) mode.

Brushless Actuators

Rugged drone actuator technology for harsh environments

DA 15-N Brushless Actuator

The DA 15‐N is our smallest and lightest full brushless actuator, designed for use in harsh environments and tested for over 4000 hours. With a brushless motor and contactless position sensing system, the DA 15‐N greatly diminishes electromagnetic noise and is immune to wear, vibrations and shock. The HART‐coat treated aluminum housing is saltwater‐resistant and is IP‐67 rated for water and dust protection.

The DA 15-N provides a peak torque of up to 60 Ncm at 6-16V.

DA 22-BLDC Brushless Actuator

The DA 22-BLDC is a brushless version of our proven DA 22, featuring rugged IP67-rated construction for harsh environments, rigorous testing to MIL-810G standards, and a contactless position sensing system for wear-free operation and long lifespan.

Featuring various housing options, including mechanical compatibility with the original DA 22 for drop-in replacement, as well as a submersible version. Volz also offers customization possibilities for the actuator housing and connectors.

The DA 22-BLDC actuator technology provides a peak torque of 3.5 Nm and is available in either 12V or 28V versions with PWM or RS-485 interface options.

DA 30 Brushless Actuator

Our 30mm class of actuators features a brushless motor and a contactless position sensor for maximum service life and reduction of electromagnetic emissions. The HART‐coat treated aluminum housing is saltwater‐resistant and is IP‐67 rated for water and dust protection.

Diagnostic information such as motor and electronic board temperature, internal humidity, current consumption and supply voltage levels can be read using the RS 485 interface.

There are several communication interface options available: opto‐coupler PWM, TTL PWM, serial RS-422, or RS-485 with 2-wire, 4-wire and redundant RS 485.

The DA 30 provides a peak torque of 16 Nm at 28V.

Throttle Servo Actuators

IP-67 rated, shock and vibration resilient

DA 20-TS Throttle Servo

The DA 20-TS throttle servo is a fully programmable, compact fly-by-wire actuator for direct installation on the throttle valve shaft of a combustion engine. It is IP-67 rated, immune to shock and vibration and designed for use at high temperatures.

The RS-485 digital serial command interface can be used to monitor the shaft position as well as diagnostic information such as the supply voltage, the current consumption, and the temperature of the electronics.

The DA 20-TS provides a peak torque of 30 Ncm at 28V.

OPV Actuators

Actuator Technology for Optional Piloted Vehicles

Volz can provide actuators with electromagnetic clutches for Optional Piloted Vehicle (OPV) applications.

In the event of a failure, the clutch can be disengaged and the output shaft can be freely moved, allowing the pilot to control the vehicle.

Please get in touch with your requirements.

Underwater Actuators

Deep-Sea and Submersible Actuator Technology

DA 22-SUB

We have developed several specialized actuators for submersible applications (AUVs, UUVs, ROVs). Every underwater actuator is tested in our test lab for six hours in a pressure tank under a variety of atmospheric pressures.

The DA 22-SUB is CNC machined from marine bronze and is waterproof down to a depth of 100 meters (10 bar / 145 psi). Capabilities include analog position feedback and an integrated moisture and temperature sensor.

DA 26-R

The DA 26R-30-5024 is designed for extreme depth and pressure conditions, and has already been deployed in the field down to 2000m/6600ft. A 90° angled, self-locking output drive provides constant positioning under load.

Submersible actuator housing options include saltwater-resistant aluminum or CNC-machined marine bronze. Communications can be provided via opto-coupler PWM, RS-422 PWM or digital RS-485 options.
