I have a couple of linear motors + their drivers and I'm trying to make an X-Y stage for a prototype milling machine, but I'm still a student and in a mecheng stream and haven't sized a power supply before, so not sure how to do it. So far this is my thought process:
Motor specs: 340VDC (max bus voltage), 4.5A continuous current
Driver specs: 24-80VDC, 1A max
Two of each.
Method 1
I simply do a P=Ʃn.IV calculation (n is quantity) and then size it using total watts and spec it through max voltage and max current? This method seems like overkill..
Method 2
Use the force I need this thing to exert to get needed power, then pick values of voltage and current that give this power and that are lower than the maxes. Use these P, V and I values to spec the supply?
(if this one is correct, how do you decide on what the voltage and the current are?)
Thanks in advance.
