3-Wire-Brush-Free Spindle: 600w; ER11; 48v DC; 0-9000RPM; 2-3/16″ long..
Mach3 control: You can use this to control your Mach3 machin. A guide to wiring Mach3’s motor after a driver upgrade.
Speed Readout: This comes with an LCD screen, so you can see the spindle speed in real time.
It runs smoothly, spins up quickly, and doesn’t make a lot of noise.
With no brush, no maintenance, and only dusting when necessary, this is a cost-effective option.
I think it’s worth the money. Key: The ER11 is cut into the spindle, not as a separate piece. ER has 6002ZZ bearings and the fan has 6900ZZ bearings. They are both deep groove ball bearings. There are fiber washers and wave washers. The fiber washers are used to make the top a little higher. The runout isn’t bad, but it can be annoying if you use small engraving cutters. 0.0005″ was the total indicator reading on the spindle OD near the bearing, and 0.0007″ was the total indicator reading on a 1/8″ piece of metal, like a drill “The tool shank is held in place by the collet. In this case, the 600 Watt motor measured the spindle OD at 0.0004″ TIR and the same tool at 0.008” TIR, which is the same. V-block: When I put 600 Watt motor in a V-block, I could move spindle up and down for 0.008 inches “The tool was used to measure. This is how it worked: A 0.2mm tip 15 degree V bit was used, and at 0.8mm depth it cut 0.55mm. This should be 0.41mm. It took me longer to get the job done with a 30 degree 0.1mm tip bit.
You can’t see much difference between the 500 and 600 Watt motors, but the 600 Watt one looks longer. The 600 Watt motor is shown in the inside photos. The other one is on my CNC router. Trifilar-wound: The 600-watt motor is made up of three coils that all connect to a single center tap that doesn’t come out of it. I put solder on the center tap and measured each coil group: at 2.4 Volts and 9.7 Amps, or 0.24 Ohm, for each one. With less current, I took a reading from wire to wire and got 0.37 Ohm. All of the measurements were very close to each other, so it was easy to compare them.
On the top, the air cooling holes are much bigger than they are on the bottom. I drilled a 1/4-inch hole in the end cap of my 600-watt motor “On all six holes, to improve air flow. Remove this end by pulling three long screws. It comes right off. If you pull out the rotor, be very careful to keep magnetic things away from the rotor. To clean it, use blue tape.
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. I don’t know why (same driver).
These spindles are better than brushed DC ER11 spindles with the pressed-on adapter. If you need zero runout, this is not the right tool for you. In my belt-driven CNC machine, this has runout and slop.
