Thread: Spindle motor rewind
Threaded View

I have an HSD spindle which I plan to use on my VTX1 rebuild, it is rated at 5Kw 380v 2 pole 400hz. I am running it on a vfd at 240v at the moment.
I am looking into the possibility of getting it rewound as ~ 3Kw 240v 8 pole 400hz. I think this would run at more suitable speeds for a mill and have more torque at the lower speeds. My VFD will actually go to 1000hz so could still get~ 18000rpm.
Perhaps even a pole changing winding, though I am not sure how the VFD would cope with that.
Has anyone gone down this path - what are the snags etc - there are always some
I did note from a search that John S had dabbled a little in rewinds.
