Hi,

It's been a while, but i'm finally going buy myself a motor spindle. Wanted a 1.5kw, air cooled with invertor, preferably from a uk warehouse,

Saw this one on ebay

1.5KW AIR-COOLED SPINDLE MOTOR 1.5KW INVERTER DRIVE VFD GRINDING ENGRAVING m9 | eBay

Anyone here know the seller: beautydirectmall? feedback looks good.

Also wondered if there have been any advances in spindles last year and a half, is this still the best to go for at the price?

Thanks in advance.

Some people have had good results with these cheap Chinese spindles; fewer have been happy with the VFDs they ship with. If your experience follows this pattern, try replacing it with a Hitachi inverter; those are more reliable (but also more expensive). In general, these spindles are supposed to be good for engraving and other light-duty tasks with small cutters, but aren't as good for heavy material removal as a more powerful spindle would be.

If you go with the Huanyang VFD and are using Mach, you can use the Modbus plug in available.
Make sure you set the minimum rpm in the parameters to 6krpm otherwise you burn that spindle out on anything lower.

Thanks both, and thanks al for the info on the minimum rpm, that's really good to know, I'll take a look at the modbus plugin. I'd like to be able to afford a hitachi invertor(also saw some made by fuji) but i'm on a budget so the idea is to go for the cheapo Huanyang VFD and then upgrade later, any idea what kind of issues people are having with them?

I'm not doing any particulaly heavy duty work so mainly wood and hopefully plastics (cut depth wont be any more than say about 5-10mm), but would like to be able to do a bit of metal engraving. IS this likely to do the job?

The Huanyang is not the best on the block for features and documentation and being user friendly, and the support is NIL.
But there are many posts in different forums, here and the Woodworking forum etc, that has all the relevant parameter settings.

lol, its got everything going for it then.

Hunting around and found the LS (formely LG) iC5 230V 1.5kW inverter. Has anyone had experience with these inverters?it's cheap which is good, but will it last?

I might add that we have had really good luck with inverters from Automation Direct at work. I'm not sure if they ship direct to the UK though. In this case the drives are connected to vacuum pumps so this isn't exactly a similar application, however the environment is hostile (hot with electrical noise and RF energy). We actually run a whole host of other drives from various manufactures and frankly if the drive meets your specific needs they seem to last a very long time. So in a nut shell if the drive is easy to hook up to your CNC controller and program you should be OK. Well given relatively new technology, I wouldn't recommend going back in time to purchase an old drive because it is cheap.

Thanks for that, i took a look and they seem to be pretty reasonable but i think after international shipping and import taxes etc it could work out a bit more expensive. I found these guys in the end Power Drive Services - Electric Motor Specialists - Inverters , and they seem to know their stuff, unfortunately the iC5 is out of stock but they recommended a Eura E2000, its chinese manufactured but they knocked £40 off the price to almost match the ic5 and told me it was generally more reliable than the Korean brand. I think I'll go for it, I also found the manual easier to understand, making setup a bit more simple for a first timer.
