Daedalus CNC Brushless Spindle Motor Kit, 500 W, ER11, 48 V DC, 12000 RPM

Exellent kit

Swapped this from an 80w spindle... No machine should come with less than a 500w LOL Everything wired up easily to my current setup of a TTC450 Pro. I'm easily cutting detailed material at 400in/min with a 2.5mm 2 flute flat endmill bit, and I think from the sound is still pretty slow. I would like to see this setup come standard with an enclosure, but that's what 3D printing is for LOL. Spindle is rated for 12k RPM, hasn't been an issue with any hardwood or acrylic for me. Definitely happy with this!

Très satisfait bon produit pour le prix

Its a nice spindle for the money! A key feature: the ER11 is cut directly into the spindle, not a separate part! The bearings are just deep groove ball bearings: 6002ZZ on the ER end and 6900ZZ on the fan end. A fiber washer is used to shim the top and a wave washer is used to preload the bottom bearing outer race upward. The runout isn't bad, but its irritating if you are using skinny engraving cutters. I measured 0.0005" Total Indicator Reading (TIR) on the spindle OD near the bearing and 0.0007" TIR on a 1/8" diameter tool shank clamped in the collet. The 600 Watt motor read 0.0004" TIR on the spindle OD and 0.008" TIR on the same tool. With the 600 Watt motor clamped in a V-block I was able to move the spindle up and down for a total radial motion of 0.008", measured on the tool. In use, a 0.2mm tip 15 degree V bit at 0.8mm depth produced an effective cut width at the surface of 0.55mm. This should be more like 0.41mm. My results with a 30 degree 0.1mm tip bit were worse: I have both the 500 and 600 Watt motors; the only visible difference is the 600 Watt one is longer. The internal photos are of the 600 Watt motor; the other one is installed on my CNC router. The 600 Watt motor is trifilar wound with all the coils going to a single center tap which is not brought out of the motor. I soldered onto the center tap and measured each coil group: at 2.4 Volts and 9.7 Amps or 0.24 Ohm. Measuring from wire to wire (with less current) I got 0.37 Ohm. All the measurements were very close to each other. My biggest gripe: the air cooling holes on the top are MUCH larger than the bottom. I drilled out my 600 Watt motor's end cap to 1/4" on all 6 holes to improve the air flow. You can remove just this end by pulling three super-long screws; it comes right off. Be SUPER careful about keeping magnetic junk away from the rotor if you pull it out! Clean it with blue tape if you do pull it out! For some reason I get 12,000 RPM on the display (and it sounds fast) with the 500 Watt motor but only 8,000 on the 600 Watt motor (same driver). This is a step up from the brushed DC ER11 spindles (with the pressed on adapter), but its NOTwhat you are looking for if you need zero runout. This has runout and slop, but its good enough on my belt driven CNC!

Very good quality product
