A major OEM received six new42 volt alternators from asupplier. Three weredestroyed in testing duringthe first month. Thats$15,000 up in smoke. They
bought SIMPLORER.
Another major OEM workedfor over a year to create anaccurate Saber alternatormodel that could be fit toparametric data. They havenot succeeded. Ansoft and
the OEM are discussing thedeployment ofSIMPLORER.

Why should you be interested?
Solving by handTime consuming
Error prone
Testing
Destroy or degrade parts
Very difficult to repeat
Insufficient quantity of parts available
Simulation
Parts are virtualdont smoke
Exactly repeatable
All are necessary to some extent and support one another.
Options are few!

RMxprt and SIMPLORER enable the engineer to study all thedesign alternatives quickly and without destroying ordegrading the properties of valuable components. With this
information highly focused testing can be carried out tocomplete the development process.
Benefits:
9 Shortened development time9
Improved performance and reliability9 Greater customer satisfaction9 Lower warranty costs
