Issue Details

I have an AC motor and I want to interface it with LabVIEW. How do I do this?

Solution

Depending on the AC motor you have this will vary. Most common AC motors are the Induction motor and the Synchronous motor. These types of motor use AC voltage to run and they are normally controlled by a device called Variable-Frequency Drives (VFD).

There are plenty of options for these drives. Some of them can be controlled by a communication protocol accepted by LabVIEW. Therefore, this will allow you to control your motor's movement.

Additional Information


It's important to clarify that there is not an NI's hardware already made for this kind of control directly. By adding a conditioning stage that rises the voltage and current, you could use an analog output device.
