The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
Hello, I wasn't sure whether to place this in the high voltage forum or here as I think both apply. So...
I have a Eureka? rotating anode x-ray tube. I won this at an auction a number of years back, but it didn't include the mechanism to rotate the anode. Can I still obtain the circuit/ mechanism or perhaps design something myself?

Mention is made of a higher frequency to turn the rotor. I do have a cycle converter that changes 60 Hz to about 180 Hz, made by Pickering. Could that be its use?
Thanks, guys. I think I get the idea, but I'm still not sure how to proceed. It almost seems as if I were to remove the center part of a motor and keep the outside coils intact, and then surround the tube with the coils, I might be able to get it to work but not sure. It may cause the rotor to spin too fast or overload the coils somehow. If it's too complicated, I'll just let the tube as-is as I don't want to destroy it. In my mind, I was picturing something like a grinder motor with the center removed and replaced by the tube. Thanks.

Yes, Peter post some pictures of the Xray tube. Add a scale for us figure out the diameter of neck .
Remove the rotor of small split pole motor (2 or 4 pole), it will provide the rotating field required to turn the anode. Single phase domestic table fan. Since the rotor is removed, the stator impedance decrease, requiring less voltage supply to avoid overload the mortor coils. 12-25 volts may be the proper voltage to feed a 120V fan.
I understad that you dont want damage the tube, Why dont add a variac keep the anode rotating slow ?

how do I rotate the anode of x-ray tube?
