Connecting 3 DC Motors to single DAQ Board

[Dennis_Knutson]

That's not a motor controller. Have you done any basic research on motors and their controllers?

Your link shows them to be brushed motors, high speed too. You can vary their speed by adjusting the voltage you drive them.

Have you ran them with your mechanics to see if they have enough torque?

Thank you for your kind and prompt response. We haven't tried to test the brushed dc motors. But we are going to try and test them tomorrow. We have shown the motors to our instructor and he said : they should be fine. But, regarding the motor controller : we have done some research and thiinking to buy two of these from this link  : https://www.sparkfun.com/products/9457 

Since each of those motor driver can control only upto two motors, we wanted to buy two of those controllers so that in one would connect two motors and for the other, we would connect the third motor.  We won't have any arduino with us. (We are only freshman and trying to do our best to make this porject succesful. We have choice to go to manual way where we would get rid of these motors...and everything and still get 100%. But there is no fun in that. We want to develop the project based on what's our idea is initially. That is why we are trying to find if someone can help us in this process). 

Seeing the information from this link, we felt motor driver would be connected to scb-68 (daq model no is : PCI 6321)  and labview will act as a motor controller.

We don't know what else we could do. I am sure I might have went wrong (or horribly wrong in the above process). We want somebody to give us some good information about what we can do and help us achieve this task!!!
