This is my first post. We are building a CNC Lathe where I work, pretty much from scratch.
We have a MagMotors DC motor from another machine we want to use as the spindle.
I'm now looking for a DC motor driver that will allow us to control this motor using an Arduino.
From what I have seen the best option we have is to use a KB Electronics KBWS-25D.
This would allow us to power it straight from the wall socket (we are in europe, so 220VAC), setting the KBWS-25D to 90-120VDC output to the MagMotor that is rated for 130VDC and be controlled by the arduino from the 0-5VDC speed control input using.
The motor is rated at 7.5A and the speed controller only for 5A. This is the only problem I can see but I don't know if that means we will not be able to reach max RPM or if it won't work at all.
Thank you in advance for your help,
