DYNAS3 LI

Low Inertia Series - AC Dynamometer

The DYNAS3 LI series is intended for all test applications in the field of high-dynamic engines. Low moments of inertia and high overload capacity in combination with superior speed gradients guarantee a highly dynamic response.

DYNAS3 LI low-inertia dynamometers are air cooled via blowers to simplify installation and to eliminate connection to cooling systems within the test cell. The state-of-the-art and future-oriented technology of the DYNAS3 series guarantees a long-term dynamometer solution at a good benefit-cost ratio.

DYNAS₃ LI is a range of absorbing and motoring machines for all test applications in the field of spark ignition and compression ignition engines. Low moments of inertia and high overload capacity together with speed gradients above 12.000 rpm/s guarantee a highly dynamic response.

The DYNAS₃ LI is part of the DYNAS₃ Series and were developed for testing a wide range of modern engines. Air cooling by blowers simplifies dynamometer installation and does not require tapping into other cooling systems inside the test cell. The state-of-the-art and future-oriented technology of the DYNAS₃ Series guarantees a long-term dynamometer solution at a low-cost investment.
