Hello,
i'm searching for an advise about this high voltage unit that i have found in an old 80's big Olimpia copier(i attach some pics),i also found 4 big motors(that i think they are unipolar stepper motors because they have 6 wires).The question is if i can use the power unit for Shapeoko or any other cnc machines and if the motors are of any use(maybe you could give me some ideas).I'm a noob but wiling to learn anything about CNC and electronics.

I don't know exactly how copiers work, but this appears to be a step up transformer,probably for the bulb. Input is 24V, outputs are in the kV range. You don't want to hook that up to your stepper driver Given that the unit takes 24V input, there is probably another part somewhere in the copier that is a 120V AC in 24V DC out power supply, which is what you want. Whether it can be used depends on the current it can source.

*edit after some quick research (wikipedia) it appears that the high voltage is used to electrostatically charge a photosensitive drum

I hope this is a joke, but just in case it isn't, don't use that power supply for anything. Those high voltages are dangerous, and completely useless to you. What you need is a power supply that takes whatever the mains voltage is in your country (100 to 240 V at 50 or 60 Hz) and outputs 24 V DC. Your supply has a 24 V input. With the risk of sounding like a dick, if you don't understand electricity, better be on the safe side and not mess with it. You can set your house on fire even with 12 V or 24 V (and a good dose of bad luck) -- but that power supply can kill you, and someone trying to save you after you're dead.

About the motors, all the information we have is that they (1) came from a copier, and (2) have six wires. They may be good, or they may not be.
