Hi guys/gals,
this should be easy to find out, but in all honesty, I'm not sure what I actually need to google, so am struggling to fine the required information.
In short, I have an old brushed motor, think electric drill, that I need to test. All I have is the motor/housing, but the switch/control electronics are missing. All I need to do, is to power up the motor a few times to take a few torque measurements, then bin the whole lot, but I'm struggling to figure out what exactly I need to do that.
Full details are, it's an old 1980's electric impact driver that was used to actuate a power drawbar on an old CNC milling machine. The impact driver was stripped of it's original switch/electronics, and wired directly to a custom power drawbar controller for the impact gun that simply accepted signals to tighten/slacken. The original machine controller was removed long ago, so I have no idea what signals/power was even supplied to the power drawbar controller. The gun has 4 wires, 2 of which power the armature, and two that power the field coils.
All I want to do, is power up the impact driver to see what it's maximum torque is that it tightens bolts to, and then replace it with an air impact gun. However I can't locate wiring diagrams for the specific controller fitted (I do have one for an older version), and I'd rather avoid having to reverse engineer the controller to work out something that should be reasonably simple.
All I know is the original impact gun is 230V and 800W.
