En perfectas condiciones y funciona perfecto

I have been very pleased with this spindle so far. It operates as advertised and is solid. I do wish I would have gotten a larger one that could hold a 1/2" shank.

Only had it for a few weeks and done a few cuts with it, but it works perfectly with a Vevor VFD and I measured only about .0003" runout in the spindle taper, so that's plenty good for my purpose.

Many CNC spindle motors you get in this price range will be 4 pole. This 2 pole motor provides exceptional power and torque at the rpm range where you expect to use 3/8", 1/2" or even 1/4" tooling. It's a bit on the loud side like most air cooled spindles but this makes it relatively maintenance free.

Obviously just got it cannot say how the power is yet but it feels like it is well made, only run it at 3000 rpm to break the bearings in.Used it to replace a perske 7hp I know it will not compare in power but for my use it should be fine.Was looking at the 4.5kw but it shows only having 3 mount holes on each side where even a 1.5kw has 4 holes on each side. That stirred me away .
