Motor Analysis using Compact RIO - NI cRIO-9022

[BigRedNI]

Hello All,

I wanted to ask the community about their experience when selecting the modules needed for their compactRIO.

Without going into too much detail I will explain my design.

I am working on a project that will analyse the essential parameters of a motor supposed to fit onto a F1 car. The purpose of this project is to simulate the Motors working conditions as if it was in the car on the track when it is actually in a laboratory.

The current test consists of our test motor attached to another motor via a coupling, this 2nd motor is meant to provide a load to out test motor and is applied via an attached load bank which just varies the amount of resistance added by the 2nd motor.

I want to use labview and my compact RIO NI cRIO-9022 to record data and such from the experiment.

I have little experience in design so I am having trouble selecting what modules will be needed for this kind of experiment.

The experiment will consist of 5 sensors altogether; Voltage, current, Load (2 at each side to account for difference) and an Encoder to determine RPM. I do not know how these 5 sensors will interact with the compact RIO as there are so many modules to choose from.

I have attached a png file showing the experiment as a block diagram. I am not concerned about the price of the modules, whatever is neccesary.

Thanks to anyone who responds,

Kind Regards,

BigRedNI

Nothing particularly unusual there, so should be possible using the correct c-series modules.

You'll need to consider what type of signal V and I is (AC, DC, chopped from an inverter) and what things you want to calculate from them. You may need high sample rates to capture phase shifts, or calculate instaneous power. Get module that has simultaneous sampling if you want to do that. Then consider what the signal levels are to see what cards fit your need. Some external signal conditioning (e.g. current transformer) may help get signals down to the levels.

Load cells are also fairly standard but need to understand the specific load cell and the type of bridge and/or excitation voltage that may need to be supplied.

Plenty of white papers on ni.com that explain the detail of these issues.
