Hi.. I have a 5.5kw ATC Water Cooled Spindle that was damaged...motor guy says windings ng...Does anybody know if these can be repaired? Or do you just have to get new?
Thanks

To have a reputable rebuild shop redo your spindle would probably cost more than a new Chinese replacement. If you are a job shop, might pay to have a replacement on the shelf.
Being a 5.5Kw ATC it may be worth doing, but you need to find the reason for this to failQuote:

Hi..thanks for replying...it was running for a year or so..then someone was cutting some carbon fiber with a special cutter and somehow the cutter tried to cut way too much at once and quickly...spindle stopped...thought at the time the inverter alone was fried...didnt use till few months ago...got new inverter (10hp) .started to set up ..didnt work..sent to motor guy..he said windings ng..he said he could rewind but to research replacement stator..asked Helen @vipwindows...she said couldnt supply only option to send back...$1200
So I am researching what I can till I hear from motor guy.
Thanks again
Ok then the VFD was never setup correct is what caused this whole problem if the max spindle amps and max voltage was set correct this would not happen, the VFD would of gone into a fault there are many Parameters that need to be set for the protection of the spindle and the VFD if they are not set this will always happenQuote:

It is not so easy for a person to repair a spindle. You could ask for some professional service if you think it is worth doing so.
There are tow links for your information.

P.S. $1200 is a little bit expensive. Another thing, what spindle brand are you using?
Hi..thanks for reply...it is an ATC so it has even more value to me..the model is by Changzhou... 120TD18Z5.5A
Steps to completing a rewind:Quote:

Once unit is approved for rewind, full schematics will be produced to ensure every aspect of the windings is replicated using top materials.
The unit will then be stripped of the old copper using a cold stripping method to ensure preservation of the laminations.
Beginning the winding process includes spraying the laminations with varnish and inserting insulation exceeding manufacturer specs.
Coils are then wound on a computerized winding machine to ensure proper wire layering form.
Once all the coils are inserted a full connection of the coils will take place replicating factory data.
Full testing of the windings will take place before the unit is ready for varnish coating.
QUITE DIFFICULT, RIGHT?

If they do a rewind they will need custom made wrenches to take it apart also, not using the correct tools will damage your spindle parts and mess up the balance of the spindleQuote:

looking for guidance in terms of inverter setup..
Thanks
What is the ratedQuote:

Hi...max is 18000....no minimum written.Quote:

See how this goes for you there may need to be so adjustmentsQuote:

Hi...my book from inverter has different parameter prefix..like p2.01=motor rated power..
Also in checking spindle with multimeter..I get .2 on all 3 wires when checking wire to wire...not sure if that is good or bad?
Thanks
