Test stand design for high speed brushless dc servo motor efficiency testing

[Dave@Ventec]

We are in the process of designing two test stands around the brushless dc servo motor in the attached specifications.  The first we would like to operate using Labview and a PXI-7352 controller.  The second will be a real time configuration.  The motor will need to run in the 25-50,000 RPM range.  We want to bring the hall sensors back to the controller and do PID and other control there.  The sinusoidal commutation from the controller would then go to an as yet unselected servo amplifier.  When the motor is under test we want to be able to measure accurately the power that is being used by the motor - not the motor and controller / amplifier.

Can the PXI-7353 handle this motor speed range?

Will Labview and the PID toolkit be sufficient software to program the first test stand?

Any example VI's available for this approach (I could not locate any)?

What is the appropriate controller for a real time system?

What is the best way to instrument the motor to determine power required at a given test point?

Any suggestion on a servo amplifier?

Thanks in advance,

David

Mr. Zaatari,

As you will note, there are six questions posted above.  As you also know, I have been waiting for your response for 5 days and decided to use this alternate method in hope of getting my questions answered.  As you further know you have not answered these questions.   It is a shame that you will  not post your "answers" here so that the rest of this wonderful NI community might have the benefit of your knowledge as well.

I will respond further to you by email.

David
