Capabilities to analyze dc brush motor performance

[sandiegogator]

I was wondering if there is any existing DAQ cards used to analyze the performance of a small dc brush motor.  I am looking to put together a torque speed curve of our existing motors.

Hi,

National Instruments makes Data Acquisition Hardware which will acquire that data for your system. Are you trying to perform some encoder measurements on the motors or acquire some analog data? Also, with LabVIEW, you can view, analyze and modify your data to fit your specific needs. Do you currently have any DAQ hardware for this application?

Regards,

I am trying to acquire some analog data.  It would be nice to get a voltage, current, and speed curve.  I will take any of them at this point.  I am currently using an NI-DAQ 6025E with a CB68LPR connector block.

Hi,

There are some great shipping examples for acquiring analog voltages and currents in the LabVIEW Example Finder. Once you have the DAQmx driver on your system then you will have the shipping examples.

Voltage: open LabVIEW and go to Help >> Find Examples >> Hardware Input and Output >> DAQmx >> Analog Measurements >> Voltage >> Cont-Acq&Graph Voltage-Internal Clock.

Current: open LabVIEW and go to Help >> Find Examples >> Hardware Input and Output >> DAQmx >> Analog Measurements >> Current >> Cont Acq 0-20mA Current Samples-Int Clk.

I hope that this helps you with your application.
