Motor control using labview

[MrCoolMan]

I'm new to Labview. I just installed a new labview system with analog output.

What electrical component do I need so that I can power a decent size motor with labview output? The signal from Labview is only enough to power a tiny motor. Well, the only thing I know is to amplify its voltage using opamp, which doesn't do much since I need to increase its power.

I don't have good electrical background, but I'm trying my best to learn.....

Please help experts.

MrCoolMan-

This depends on several things.  I have a few questions about your application:

1. What National Instruments Hardware are you using to control your motor?
2. Are you using a Stepper or Servo Motor?
3. How much power does your motor require?
4. How are you planning on controlling your system?
5. Does your motor require an analog or digital signal?

The answers to these questions will be a good way to get started with your application.

You should use a versatile motor driver I bought from www.robotservice.se an servodriver, Step, DC motor drive that i can control directly from Labview via USB cable delivered with driver and free lib to control motor with torque or step distance very easy. This unit cost only 270 €. I have used this for building a prototype machine 4-axis with both AC-servo motor, DC the AC servo i power with 160VDC, and the dc motor 24 VDC with the same hardware, with diffrent setup that you can edit direct from PC or through Labview.....
