Development of combustion engines on engine test stands
DYNAS3 HT
High Torque Series - AC Dynamometer
High rated torques make DYNAS3 HT dynamometers optimally suitable for testing small and medium-size diesel engines. The wide speed range also permits the testing of spark-ignition engines. The torque behaviour – in combination with high speed gradients – provides the dynamic response required for sophisticated simulation tasks. The DYNAS3 HT series of dynamometers are universal driving and absorption units. The components of the system have been optimized through many years of experience. The DYNAS3 has defined and standardized interfaces which significantly simplify the engineering process involved in setting up the dynamometer to run with your test specimen.
- Unique combination of speed and torque characteristics for a wide range of test applications
- Providing a torque range up to 1,484 Nm in combination with high speeds and dynamic behaviour
- Compact motor design with power range up to 460 kW
- Air-cooled dynamometer for easy installation and upgrading of existing test cells
- Measuring flange for highest torque measurement accuracy of real shaft torque
