Compact Servo Drives with Ethernet Connectivity

Use your favorite programming language like Python, C# and others to control the HDrive17-ETH-i servo motor.

No need for PLC equipment, use any ethernet capable device to control the HDrive17-ETH-i

Save costs and time during development

The HDrive is a full featured, closed loop servo drive. Everything from the sensor system up to the power electronics is included. There is no need for an external axis controller.

The embedded software provides state of the art servo drive functionality like an accurate position controller and a rich path planer. Multiple operational modes like position, Torque or speed-controller are implemented.

The HDrive17-ETH-i is the smallest possible servo drive with Ethernet available.

Superb Web-interface

The HDrive17-ETH-i has a build in Web-Server. This allows to configure and also to control the servo drive. The interface can be accessed by navigating with a browser to the drives IP-Adress.

It is also possible to update the Firmware of the drive and also the Web-Gui. It also allows to upload custom a custom Web GUI as shown in on of our Tutorials:

HDrive23-ETH-i with 2 Nm stall torque

Finally we are ready to ship the HDrive23-ETH-i units. The same concept but a 57 mm x 57 mm motor with almost twice the stall torque than the HDrive17-ETH-i.

The new HDrive32-ETH-i as well as the HDrive17-ETH-i are sharing the same core software and the same Web-GUI. Thus you don’t have to distinguish – The firmware always fits. Thus this fresh drive inherits of an over 5 year experienced firmware.

Industrial experience

The Henschel-Robotics Servo drives are the first choice for PC-Controlled machines.


Whenever it gets more complicated – with the HDrive system you can write the whole control logic in a high-level programming language like C#, Python, Java or C++. Thus, it’s in your hands on how scalable your industrial application will get – it does not relay on the IDE of any PLC manufacturer.


Also benefit from source control tools like GIT or SVN when developing an industrial machine control. You can also benefit of unit testing and automation releasing with Jenkins and co.

Rock solid design

You can rely on our drives and their code inside. 

Our drive is built using best practices and modern electronic components. Although, the HDrive is engineered and produced in Switzerland entirely.
