ds motors

[Georgije]

hello
I need help generate a PWM signal procession, and the procession to take the switch, which will include the DS engine and so he changed the mean voltage.

Thank you,

Need more info.

What is a "ds motor"?

What switch are you talking about?

Who is "he"?

What mean voltage are you talking about?

The idea is to make the code in LabVIEW, which would generate a PWM signal, which is meant to put the management of electromotor direct current-DC motors. This PWM digital signal, which should be such frequencies. 5kHz, should lead to a switch, which will include the motor and send him a PWM signal.

I'm sorry but I do not speak English, I'll do my best to explain it to you.

Thanks for your help

Look for Square Waveform.VI in the Signal Generation palette.  It creates a waveform and lets you set sampling rate, frequencey, duty cylce % .....

Hi Georgije!

What hardware would you like to use to control the motor with the PWM?

There are a lot of examples on NI Community about PWM generation, but it would be good to know the HW you will use.

Here are some:

Using this example below, you can create your own solution, that uses just digital lines: https://forums.ni.com/t5/Example-Code/Pulse-Width-Modulation-PWM-IP-Core-for-LabVIEW-FPGA/ta-p/39961...
