Water-Cooled Spindle Motor
The diameter of the spindle is 80mm, using scientific water circulation design, the heat dissipation effect is better, which can ensure the smooth running of the spindle.
Low noise
Humanized noise reduction design, low noise when the spindle is running, can create a more comfortable working environment.
High Quality Bearings & ER20 Collet
Using optimized bearings, this series of bearings has strong hardness and rust resistance, as well as dynamic balancing technology, the actual runout off of the spindle is close to 0.01 mm, the precision tapered bore is less than 0.005mm, high precision and durable.
Stainless Steel Material
Stainless steel material has high hardness, strong corrosion resistance, fine workmanship, and enhanced service life.
How to Connect Spindle Motor and VFD
The spindle motor's aviation plug marked with number 1, 2, 3, 4.
Number 1, 2, 3 port are connected separately with inverter's port U, V, W.
Number 4 is the ground wire, no wiring is required.
Applications:
Spindle speed up to 24000 rpm, usually used in CNC router engraver milling machine, can be engraved wood, plastic, acrylic, pvc, pcb, carbon fiber, density board and soft metal like copper, aluminum and the similar materials.

The motor we received didn’t work. We returned it and decided to try a different brand of motor.

Awesome performance for a miniscule price

This spindle works great. The only issue I have with it is the connection plug. It should only allow connection in the proper orientation, but it can be connected correctly, and 180 degrees off. When you build your cable connection be sure to connect the plug in the proper orientation.

The plug is not set to be orientated correctly and the seller will not respond with correct connection information. Connections are in a random order and not labeled correctly. I would never consider buying from kuku tech again

This unit over heated and died within 6 hours. Do not recommend. Ordered a different mfgr replacement.

This spindle appears to be properly maid. I did not use it in operation yet, but it runs pretty smoothly at various speeds all the way to 24000 RPM. I use a Hitachi WJ200 VFD to drive the motor and still need to optimize the VFD parameters.The first thing I did was to check the ER20 socket runout. It was less than .0001". A 6 mm collet, which came with the spindle, was not really 6 mm, more like 5.8 mm. But it still ran within a few tens, checked on a ground pin of appropriate diameter.I have a brand new Techniks collet, which checks very good on taper angle and runout. I have used it to check the new spindle. Taper angle looks good with "Bearing Blue" paste. The runout of the 1/2" pin in a collet varies from .0001" to .0003", measured about 1" away from the collet face. This is better than advertised and I am happy to see that. The collet nut threads are a little too sloppy for a good fit, but the runout on its OD and face is only a few tens. In addition the nut is balanced.In addition to Techniks collet I've got 2 new Chinese ER20 collets in 3/8 and 1/2" sizes from a different seller. They are made extremely poorly with tapered bores and .003-.011" runouts. My advice - stay away from such bargains.All my attempts to get any information on internal spindle construction failed. The seller does not know anything about the product. The factory promised to supply the information, but did not deliver. So the only way for me to find out the details is to take the spindle apart, and I am not ready to do that yet.My overall impression of this spindle is good, but like I said before I did not test it in real working conditions.
