Motor with a DAQ USB 6008?
Posted 28 December 2010 - 08:00 AM
However when I asked my professor about the idea, he said that using a fan(motor) with the DAQ USB 6008 would make the DAQ's circuitry fry due to the large power required by a motor. Is that true?

Might I ask why that is that I shouldn't wire the motor directly?
For exactly the reason your professor mentioned - the analog output on your USB 6008 (and pretty much any analog output on a similar device) cannot supply enough power to run a motor. The analog output is designed to act only as a control signal. The digital outputs on the 6008 are similarly limited.

instead of a relay output, try to use a power mosfet , where the gate will conected to your analog output from 6009, That way you will be enable to control the velocity of the motor using your analog outpout.
There is another solution but more complicate, like PWM controls.
For initialization will be a good project using the mosfet.
Good Luck in the project.
