    Chinese Spindle Repair

    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 fail

    How long has it been in service

    Re: Chinese Spindle Repair

    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 happen

    Going by what you are saying you may be better off with a new spindle, and look at the possible repair of the damaged one

    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?

    Steps to completing a rewind:

    Fully test windings for any possible problems using the industries top equipment.
    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 spindle

    looking for guidance in terms of inverter setup..

    Thanks

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

    Huanyang
    5.5Kw 380v 600Hz Water Cooled

    PD000=0 ( 0 For Parameter unlock ) ( 1 For Locked )

    PD001=0 (1 For Remote Control)

    PD002=0 ( 1 For 0-10v Terminal Control or Remote Trim Pot Control )
    ( J1 Also Needs to be set for Remote Terminal Control 1-2 jumper connection )

    PD003=600

    PD004=600

    PD005=600

    PD006=300

    PD007=20

    PD008=380 (Motor Rated Voltage )

    PD009=190

    PD010=12

    PD011=120 ( Minimum RPM Setting )

    PD13= 08 (is for Factory reset, Only use this to set VFD to Factory Default Settings )

    PD014=8 ( Acceleration Adjust to suit)

    PD015=8 ( Deceleration Adjust to suit)

    PD023=0 ( Forward Run Only )

    PD041=8 ( Carrier Frequency up to 10 Max for these Spindle motors)

    PD120=120 ( Stall Prevention )

    PD141=380 ( Motor Rated Voltage )

    PD142=12 ( Motor Max Amps )

    PD143=4 ( Motor Number of Poles)

    PD144=3000 (Max Motor RPM) 3,000= (18,000)

    PD070=0 ( This may need to be set to 1 if Control Voltage is 0-5v )

    PD072=600

    PD073=120 ( Minimum RPM )

    PD174= ??? ( To Be Set to the VFD Drives Max Rated Output Amps )

    Re: Chinese Spindle Repair

    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
