The EMA (Electro-Magnetic Actuated) damper dynamometer
is a serious tool for racers and damper manufacturers alike. Its
versatile, and boasts performance features like a 0.010 to 7 inch (.25
177mm) stroke range, frequency response above 100 Hz, and velocities in
excess of 3 meters per second. This machine is a must-have piece of
equipment for any research and development facility.
The EMA is a true linear actuator. It provides extremely fast response
as well as excellent positioning accuracy, while eliminating backlash,
windup, and wear. Two models are available to fit your testing needs
EMA-2K: 2000lb (8.9kN). force, EMA-4K: 4000lb (17.8kN) force
The EMA can play back track data collected from a number of commonly
used onboard, automotive data acquisition systems. Partial, full, or
multiple lap play back is possible. EMA is also fully capable of
reproducing sinusoidal waveforms identical in comparison to our
industry-standard crank-style dynamometers. In addition, triangle,
square, and composite custom waveforms can also be generated and driven
through the EMA system, which is used in conjunction with our Shock6.0
Test Control and Damper Analysis software.
