The three-phase asynchronous generators are designed specially for test rig applications and

• require little maintenance, therefore increasing the availability of the test rigs
• reduce the amount of space required due to their compact design
• measure statically and dynamically accurately with the integrated dynamo hub
• are low in vibration and noise up to 10 000 min-1 (depending on performance)
• have a high rigidity due to a special end plate construction with integrated air ducts
• have a low rotor torque and moment of inertia, thus also allowing dynamic measurements.

The generators which have been proven over long years in use are powered by industrially proven SIMOVERT®converters.

The new dynamometers are a forward-looking solution for continuous test rigs as well as for examining transient processes or realistic simulation of vehicle stresses on test rigs.

They are also ideal as drives for high dynamic operation for practical simulation of the drive chain, vehicle mass, road load and driver on the engine test rig.
