Really need help (motor control using labview)

Question

hi all readers,
im new beginner. really need help for my project. i've been assigned to monitor/control motor using labview 8.5 (using NI DAQmx). the problem is, the techinician told me that i cant use 3phase motor with this card. things that i need to displayed using labview is :
torque
power
current
voltage
speed
really appreciated if readers can help me with this:
wut type of motor shud i use that compatible with NI DAQmx
thanks a lot.

Hi fauziana,
NI data acquisition devices are primarily designed to take measurements, so it's a good idea to measure the signals that you have mentioned with a DAQ device.
You also can use DAQ devices for control tasks, but for reliable and deterministic control behavioryou typically need to use a real-time operating system (not Windows!). If you want to learn more about the pros and cons of using DAQ devices for motion control tasks, please refer to these threads. Still for standard motion control tasks it's much more efficient in terms of development time, to use a dedicated motion control device for the motion control part of your application.
In general the control part is independant from the motor type, as these devices only generate control signals (+/- 10 V). There are many power drives available, that accept this type of control signal and you should select your motor according to the requirements of your application.
For a more detailed system consulting, please contact your local NI branch. To select the products that fit best to your application requirements a face to face discussion is much more efficient than a discussion forum thread, because there are a lot of parameters that need to be taken into consideration. If you tell me in which country you are living, I can provide appropriate contact data to you.
Thanks and kind regards,
