Hi Clive, the spindle has got 4 entries whereas the VFD has got 3 entries. Do i need to use the same cable for both connections? Also, should a power supply for the spindle be included in the package that I have bought?Quote:

See the first post in this thread for connection details.
Valeria, It sounds like you have very little experience with electronics so I seriously suggest you get someone with more experience to do this for you.Quote:

Yes and potentially do yourself some serious damage. If you're not 100% certain get an electrician to wire this up for you. With mains voltage, it's better to be safe than dead.Quote:

It seems quite cheap for that power. Too cheap?
Some of the pictures of 3kW spindles says 380V. Anyone has experience with 3kW spindles?
Has anyone measured runout of this spindles and checked how many bearings they have(if that makes any difference?)
Best regards

Just wired my spindle and VFD and followed the diagram in post 1 and it kept tripping.......that was because the pin numbers were different.....
Attachment 15689
Had to cut and re-wire the VFD end as the spindle end is soldered.......still it works now so all good. Just have a look on your connector if you've got the 4 pin variant that's all :stupid:
I recommend checking with a multimeter what the resistance it between each of the pins, as who knows if the companies making these spindles are consistent. You should get a couple of ohms between the motor terminals and zero ohms to the spindle body, or high impedance when they don't bother with the earth.
Hi everyone.
FYI, I just ordered a complete spindle kit from Kevin Ho at ROB BEARING AND MECHANICAL PARTS on AliExpress.
They don't sell it as is, but if you contact him they'll make you a better price than the kit for which I gave the link. Instead of 417 Euros from the original seller (288€ kit + 129€ shipping), I paid 360€ (US $400 round !). I haven't received the kit yet, but I have made quite a few orders with this seller and everything arrives on time and in great condition. Always well packed. He's even offered me some couplers I had forgotten in my last order. It's a factory that produces linear motion stuff but they can order anything you want.
I'll post pictures of the kit when I receive it, but I have no doubts it's worth the price.
Only thing missing is a nice bucket of water, that will prevent you from having to buy a radiator and a fan. With 20-25L bucket you're good to go... you'll be long dead before your spindle raises the water temperature by 10°C !
