Spindle motor replacement Bridgeport 412 tips

Hi,I’ve been working on my Bridgeport 412, and everything was going great until I discovered that the Fanuc control for the spindle motor is broken. Initially, I considered using the STMBL project with the Fanuc motor, but I’m running out of time, and the massive transformer required to run it is proving to be a nuisance.I’m now thinking about replacing the spindle motor and driver with a Chinese one. The replacement would have the same power (5.5 kW) but slightly more RPM (4000 instead of 6000). Since the machine could have been configured for higher RPM originally, I think this should be fine. The only adjustment I might need is to make a new pulley if the old one doesn’t fit.My machine primarily uses EtherCAT, but the Chinese servo I’m considering doesn’t support EtherCAT. It does, however, have CAN control, and I could also use its analog control interface if needed. The dimensions of the motor seem similar to my existing one, though I’ll need to double-check this weekend.I’ve gathered some information from the Alibaba seller. The entire kit (servo motor 5.5 kW 6000 RPM, servo driver, wiring, and resistor) costs $600 USD, excluding shipping. I estimate shipping will be an additional €200–300. I’ve never ordered through Alibaba before, so I’m curious about others’ experiences with the platform.Since I’ve never done this kind of replacement before, I’d really appreciate any tips or advice. Does this seem like a good choice, or are there other factors I should consider? Have you had any experience with replacing broken spindle motors or drivers? Does the price seem reasonable? I’ve assumed that items purchased on Alibaba are similar to those on AliExpress, and my experience with AliExpress has been that they deliver exactly what they promise.Looking forward to your insights!

Well, I will need to orientate it for the changer. I was thinking that I can just run it velocity mode and use the encoder to orientate it. I did see something about a homing feature. However I will need to double check that.
