Connecting 3 DC Motors to single DAQ Board

[siks1]

Hi,

For one of our project we are seeking help from someone who could actually help us progress our project. For this project we are using a stepper Motors (each 12 V) to run the gears as per below shown picture . Our project idea uses 3 steppers motors (the picture shows just one motor). So we want to know whether is there any way we can connect 3 motors to a single DAQ Board (Model No : SCB 68)? All we want to program in the labview is to note the time it takes for the piston (connected to gear) to move to a certain distance and repeat it for the certain no of times (according the input user gives)  and stop the motor after it reaches the input count. Can you please guide us/help us to make our idea successful? We would be so happy, if someone can help us in connecting these 3 motors to single daq board and make it work like the way we want to..! Thanks, MSC

You can connect the motors any way you want to an scb68 and never get anything to work because the scb68 is just a dumb terminal block - not a daq device.

Oh ok. Sorry for my limited knowledge related to this because I am still a freshman student trying to learn and use Labview properly.

I believe we have a DAQ Card also ( I will let you know the model number for it). I am trying to think that, the motors will be running if we are able to generate some power from terminal block (or may be by using external power terminal) to which the 3 motors will be connected and then to control these motors (each of these motors to start and stop after rotating certain angles) will help us make this project successful! Is it possible ? Can you give us any guidance in this regard? Thanks, MSC

Daq Device Model No : NI PCIe-6321

Motors we bought (link) can be accessed here :

hope, this information enables you to help us. 

Thanks

Shouldn't your professor be giving you some guidance on this?

Not really!

Why not really?

[siks1]

because it seems like a bit lot of work to her as she even need to concentrate on other teams,

Do you have a suitable controller for the motors? You can't drive them directly from the DAQ card - not enough current or voltage.

We have hewlett packard E6360A 0-6v, 2.5A/0- +/-20V, 0.5A triple output dc power supply.

Do you think it would work?
