VEVOR Water Cooled Spindle Motor 2.2KW Spindle Motor Water Cooling 220V 24000rpm 400Hz ER20 Water-Cooled Spindle Motor for CNC Engraving Milling Machine

I've owned another one of these bought from a different supplier, and that wasn't grounded on the body, however, this one was and I'm really happy with it so far, it's very quiet and it comes with good quality spanners and a couple of ER20 Collets to get you started

Pros:- cheap spindle with a beefy power ratingCons:- the instruction sheet claims that the spindle body is earthed, which is not true (checked continuity with a multimeter). This is the main reason why I am removing 3 stars from this review. Saving costs is fine, but lying about a critical safety feature crosses the line.- the Phillips head screw sockets for the spindle-side power connector were already stripped out of the factory- the proprietary 'H17' connector (cable-side) is too small to fit an adequately sized multi-core cable (9.0 mm jacket diameter in my case). The maximum that will fit WITHOUT the rubber sleeve meant for waterproofing is approximately 8.4 mm. With the sleeve, this drops to 6.0 mm. Since increasing the cable gauge (i.e. decreasing the conductor area) is not an option, the only solutions are to either file down the casing to a suitable diameter, or to run only the conductors into the connector (in which case I highly recommend you reinforce the first 20 cm with copious amounts of heat-shrink).That being said, I knew what I was getting myself into by buying this product. It's cheap, but you'll have to put in quite a lot of extra time to get it working safely.

The company was spot on, really helpful. Once received, and it came early it was well packaged .Not nor fault the business or the spindle

very good value for money .
