I am very new for raspberry PI. But I have to make system where I can controll 2 AC motors. (220VAC)
I hope you can give me information about things what I need to do that.
The main idea is that both motors will start at same time, but the load and forces that brakes them could be different. When motors start to spin their torque have to be low, but then it must increase until predefined current reached and then cuts off. And I have to monitor current drawn by motors.
I have seen a video where it is done with dc motor and much lower power. (https://www.youtube.com/watch?v=_MCxxdKj5os)
I'm sorry couldn't find any video with raspberry PI!
So power for each of motor would be 2kW in my case. So I need much more things than DC setup.
For starting motors at the exact same time I could use motors with build-in encoders, right?
For controlling motors is there any other option without VFD?
What things I have to consider?
Maybe better 24 or 48 V DC motors? But then I need some transformator...
Once again, I am new for all this stuff, but I hope, that you could help me! Ask me questions I could try to answer them.
