Thank you for the links.
Actually I need the softwares to validate one that I wrote by myself.
When I do balancing I use non contacting probes to get displacements and a phase transducer built in the motor.
I see that the softwares are really expensive, and I see no reason for this. Maybe I will release my "master piece" as a freeware, it will be able to do multiplane balancing, it is written in Delphi for the user interface and Fortran for the number crunching. Unfortunatelly I won't be able to check the results for more than 2 planes because I have no data for this.
