ECODyn H series (High Speed – Low Inertia)
The drive and load machines of the ECODyn H series are intended for test bench applications with Otto engines.
Their low mass moments of inertia and high overload factors allow high speed gradients of up to 19,000 rpm/s and thus high dynamics.
The basic scope of ECODyn H modules for combustion engines always consists of:
- an asynchronous machine with torque measuring flange and speed sensor
- and a converter system with supply unit and inverter unit,
- ready-planned as a module

ECODyn M series (Middle Speed – High Torque)
The drive and load machines of the ECODyn M series are designed for test bench applications with small and medium-sized diesel engines as well as large Otto engines. Their high torques in the nominal speed range and their wide speed ranges offer speed gradients of up to 13,000 rpm/s and thus dynamics for demanding simulations.
The basic scope of ECODyn H modules for combustion engines always consists of:
- an asynchronous machine with torque measuring flange and speed sensor
- and a converter system with input rectifier and inverter,
- Ready-planned as a module
