Cost effective direct drive control loaders. Robust design for a long economic life


Design & References

High MTBF. Cost Effective. Professional Model and Control software

Cost effective series of direct-drive actuators for primary and secondary flight controls, available in 3 different sizes and optional multi-turn functionality for stabilizer trim and steering wheel applications.


  • available with 20Nm, 50Nm and 130Nm continuous torque.
  • maximum velocity up to 4.500°/s.
  • the eF-DD-20/50 as well as its multi-turn version is also available in the "i" version. The "i" stands for integrated design and does not require a load cell.

Suitable for a large range of simulator applications

The eF-DD-20/50 is a cost-effective, small, direct-drive actuator for secondary controls in various simulator applications.
The eF-DDM-20 control loader (with multi-turn functionality) is commonly used for steering wheel applications in military and civil simulators.
The eF-DDM-50 control loader (with multi-turn functionality) is commonly used for trim wheel applications for military and civil simulators.
The eF-DD-130 control loader is used in military driver trainers, FTDs, procedure trainers of mission trainers to offer a high realistic and smooth force feedback for primary controls.

Option & Services

Factory Acceptance Test at E2M site
On-site assessment support
On-site aircraft measurement session with E2M’s Control Force Measurement Kit
Type specific software modelling and tuning
Mechanical Kit including frame, flight controls and linkages.

Combined solutions

eForce add-on control loading solutions can be offered in combination with E2M motion. Cost savings can be realized because less components are required. For example, one single control cabinet and one eForce RT controller can be used.

Unique software environment. More flexibility. Customizable. Accessible

  • Open and flexible software design, customizable through ASCII data files without recompiling.
  • Lua scripting engine, allows addition of any desirable characteristic on the RTPC.
  • Prepar3d and Xplane interface available, and additional IO modules can be added easily.
  • Generic Software Package can be extended based on the customers’ needs.

eDeveloper Kit (E2M Development Environment)

The eDeveloper API (E2M Development Environment) is a software tool that allows the customer to develop their own type-specific software model. This option facilitates customers having sufficient knowledge about control loading software models and able to customize the generic model in order to replicate the behaviour of the simulated aircraft.


The eMoveRT controller is a common software platform for all control systems of E2M.
Benefits for the customer: Improved quality of software, development efficiency and supportability.

Real Time-Linux/Xenomai is used as the operation system.
Protocols are UDP (Host communication) and EtherCAT (communication with hardware)
industry standard hardware is used: Ethernet hardware for communications, a commercial of the shelf industrial PC for the control software.
