WebThe purely inertial run shows a higher power result. That’s the indication that the inertia is too high. Adjust “SETTINGS / Roller 1 / inertia” and click Apply to get matching power curves. When confident that the settings … WebPower = rotational speed * rotational acceleration * inertia. Inertia value has direct influence on measurement result. It’s worth mentioning, that inertia of all bodies accelerating during the run is required for accurate result. If …

In addition to being used … See more An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires. See more In addition to classification as absorption, motoring, or universal, as described above, dynamometers can also be classified in other ways. A dyno that is See more Dynamometers are useful in the development and refinement of modern engine technology. The concept is to use a dyno to measure and compare power transfer at different points on a vehicle, thus allowing the engine or drivetrain to be modified to get … See more The Graham-Desaguliers Dynamometer was invented by George Graham and mentioned in the writings of John Desagulier in 1719. Desaguliers modified the first … See more A dynamometer consists of an absorption (or absorber/driver) unit, and usually includes a means for measuring torque and rotational … See more A 'brake' dynamometer applies variable load on the prime mover (PM) and measures the PM's ability to move or hold the RPM as related to the "braking force" applied.
