Sorry that’s a picture of the transformer in his machine not mine. But mine has one too as so many other machining centers. I’m gonna guess you don’t have experience with too many of them.
I’ve also never seen a line reactor that allows you to tap for different input voltages but maybe it’s out there.
And here is the schematic for the transformer that you seem to believe I am making up please note the top is the input with taps and the bottom are the outputs like I said earlier.
Mactec you seem like a smart guy and I’m just telling you what I’ve come across. My experience is only with machining centers and not other types of equipment. I also don’t have much experience in the hobby level stuff I typically only know the more industrial cnc machines. Brands I’ve worked on include Doosan, Mazak, Fadal, Haas, Clausing, Lagun, and a few more. I’ve owned all those brands except haas and doosan.
Now these are all commodity brand machine and not super high end like a grob or something like that. But most of them gave had transformers or had that as an option from the factory.
The one that I owned that did not have a large transformer was the Clausing lathe storm 300. It had only small transformer or possibly line reactors I didn’t look too hard as that didn’t matter and the machine worked fine.
