dynoKRAFT MPSW-Series

Water-cooled engine dynamometer

Stationary engine test system with wide Torque and RPM coverage.

Features highlight

  • up to 1100 Nm per unit
  • up to 11000 RPM
  • modular system

The water-cooled dynoKRAFT MPSW-Series stationary engine dynamometers offer exceptional high measurement precision together with best-in-class DAQ system and high speed Sport Devices PWS-HS Eddy-Current brake power supply.

This affordable dynamometer system can be used to test internal combustion or electric engines. It comes on non-adjustable chassis with stiff test bed allowing vibration-free high RPM testing.

Despite it’s moderate price the dynoKRAFT MPSW-Series engine test systems offers full test automation and advanced software for data analysis.

For most applications the dynamometer is supplied with high-flexible TOK torsional clutch. Advanced semi-automatic engine docking systems are also available on request.
Please see the technical papers in “Downloads” section.

If you require even higher RPM test ranges please contact dynoKRAFT directly.
We also offer other brake sizes torque capacity up to 3600Nm (5.000 1/min).

There are four base versions available:
MPSW120 – 120Nm – 11.000RPM
MPSW250 – 250Nm – 9.000RPM
MPSW600 – 600Nm – 9.000RPM
MPSW1100 – 1100Nm – 7.000RPM
