Henschel-Robotics is a Swiss startup whose flagship HDrive series is an integrated servo drive designed for the automation industry. Unlike traditional servo systems, HDrive tightly integrates the sensor, power electronics, and motor into a highly compact package β for example, 42x42x88mm β while delivering high torque density, from 0.6Nm to 2.2Nm, and efficiency above 90%. The product line is split into Ethernet versions (ETH) and EtherCAT versions (ETC): the former is suitable for direct PC-side control, while the latter is designed for real-time industrial automation.
In terms of supported languages and frameworks, the ETH version breaks away from the constraints of traditional PLC environments. Developers can program directly in Python, C#, C++, or Matlab, making it well suited to engineering prototyping and Raspberry Pi/IPC control scenarios. The ETC version provides a standard EtherCAT device description file, allowing seamless integration into industrial PLC ecosystems. Another major highlight is the driveβs built-in web server: developers can configure the device, monitor it in real time, and upgrade firmware directly through a browser without installing extra software. It even supports uploading custom GUIs.
Although the hardware and firmware are closed source, the built-in web server effectively provides a βself-hostedβ control-interface approach, with data and interactions handled entirely on the local network. For APIs/SDKs, the official resources include basic code snippets and tutorials. Documentation quality is adequate: the necessary manuals, 3D Step files, and product brochures are available, which should be enough to support developer integration work, though there is no large community ecosystem behind it.
The official website does not publish specific pricing, so buyers need to contact the company for a quote, which raises the procurement barrier for small and mid-sized developers. Its strengths include Swiss-made reliability, an extremely compact form factor, and a flexible development model that avoids being locked into proprietary IDEs. Its weaknesses are the limited size coverage β only NEMA 17/23 β and, as a startup brand, its ecosystem maturity and long-term service capabilities still need to be proven by the market.
This product is suitable for robotics developers, CNC integrators, and automation engineers who need extremely compact dimensions and high-precision control. As for access from China, the websiteβs connectivity is unknown. And as Swiss precision hardware, domestic procurement will inevitably involve challenges around logistics, customs duties, and after-sales response. Developers in China looking for alternatives may consider high-end options from Maxon or Faulhaber, or more cost-effective choices such as ODrive and Moons'.
