Tiene mucha potencia y hace menos ruido que uno de escobillas. Viene con todo lo necesario para montarlo en la CNC. Está perfectamente equilibrado y funciona sin problemas. Todo un acierto la actualización para una pequeña CNC.

This is not compatible with the 3018 ver2. After talking with support, they informed me I'd have to solder on the back after buying more adapters...

I initially upgraded to the "20,000 RPM" brush motor which was indeed faster, however it alike the OE motor would be noisy and cause some random chatter in my bit that would translate into inaccurate isolation trace milling.After some research I tried this brushless upgrade.So far it seems to be holding more precision in my cuts and the recused noise level is night and day.

The one I got had .002" of runout. That's huge if you are using a fine bit. Sent mine back as unusable.

ちょーっと付けにくかったですw基板バージョンはwoodpecker3.2というもので、もうかれこれ5年ぐらい前のやつです。24Vの電源はどこにも出てなかったので、DCジャックの裏から取りました。(元の設計的には大きな不確定要素ですし、素直に別電源のが手堅いかも)4ピンコネクタの黒(色w)PWMはレーザーコネクタの2ピンでも行けそうですが、途中の回路も不明なので写真の位置ICSP-MOSI(D11)が確実です。ENはオープンにしてますが動いてます。4ピンコネクタの5V GNDの要否は不明ですが、一応繋いでおきました。無負荷時は775よりも静かでキレイに回ってる感じでしたので、高い刃物を付けたら全体での騒音もいくぶん緩和されそうに思いました。※注意※candleで回転数を10%にしてからONにすると起動しませんでした!(20%で起動してから10%に落とすのは動きます)(いきなり爆速で動いたら怖いと思って10%でテストしてたので無駄にハマりました。。)

I've had this motor for a couple months now. It's handled everything I've thrown at it. I frequently use 1/4" ibit for roughing pass and it does just fine.

I haven't had a chance to run it yet, but I am very happy with the quality of this product.

The motor is fairly quiet by itself, but once the collet nut and collet are installed, it vibrates far more than the stock 775 motor and becomes noisier. I touched a tool to the round collet nut while it was spinning and the tool kept bouncing off violently, showing how badly it was vibrating. It does have a higher RPM than the stock motor but the high vibration and runout are not worth it.

It was unclear if this would work on a stock Genmitsu 3018-PROVer Mach3, as the product description has conflicting statements. I figured I'd give it a go anyway, and sure enough, it does work just fine. All you have to do is use the 24V motor cable the PROVer comes with to connect to the power cable for this ESC, then connect the GND/PWM inputs of the ESC to the GND/AV output of the PROVer controller, and you're done - you will be able to control the spindle speed from Mach3. I took a look at the PWM input circuit of the ESC, as the PROVer controller outputs an analog voltage on AV, and the ESC's PWM input is filtered to an analog voltage with a simple RC circuit, so feeding it an analog voltage directly is no problem and will behave as expected.Be warned, however, the closest thing to official documentation for this brushless motor/ESC, a post on Sain Smart's blog, is very wrong about how to wire it up. It states that you need to connect the ESCs 5V line (on the same connector as GND/PWM) to the controller's 5V output, but the ESCs 5V line is also an output, NOT an input! Leave the ESCs 5V line disconnected - it's powered by the 24V input power to the ESC, and if your 24V power supply is on a different circuit to your PC (connected via the USB cable to the PROVer's controller) it could do very bad things (and will also cause a ground loop).So far I've only done testing on plastics, but I've been very impressed with how quiet this motor is! Once I got the feeds & speeds dialled in, it made great cuts. Unlike the stock motor, the brushless motor has vent holes at the bottom, right above the spindle, which will definitely cause swarf to get sucked in while cutting, and it has no mounting holes to attach the dust shoe they sell, so I'm going to have to find a solution to that. I've had no issues with vibration from the motor at max speed, nor the motor slipping in the stock motor mount. The only source of vibration is from the 3018-PROVer's gantry and spindle mount (which I could see visibly bending when I had chosen bad feeds & speeds! Next upgrade...), and that's nothing to do with this motor.I was rather disappointed however when I measured the unloaded spindle speed at only ~8,750 RPM, which is quite far from the stated RPMs of 12,000 (unloaded), and 10,000 (operating).

The spindle is much more stiff than the stock motor. Cuts down on chatter. Also more powerful. Holds speed under load.Needed a few layers of aluminum tape around the body to get the clamp to tightenI powered it with another 24v psu and connected gnd and pwm to the cnc controller. The other 2 control wires were unused.

Received and tested on 3018 pro clone. Works as described, but with quite a few caveats that make it not really an improvement over the stock DC spindle.Firstly runout is not great, measures 0.0015" on ER11 inner taper and outer diameter, where as the stock DC is actually better at 0.001"! On a 1/8" tool this would enlarge to more than 0.005". Therefore noise wise also not much improvement, maybe slightly quieter but I suspect that's partially because the lack of a powerful cooling fan (this thing gets warm when running at full speed).Secondly, the driver and the way it's supposed to be connected is somewhat flawed. The seller recommends connecting 24V input to the driver to the "spindle" port on the GRBL board. However, the "spindle" port itself is a PWM-gated 24V signal with a low-side MOSFET, and this means that whenever you're not running full spindle speed, the brushless driver board (ESC) is 1) NOT GROUNDED and 2) being powered by a PWM wave, NOT 24V DC. To me this seems a serious flaw and potential hazard. This probably also limits the lowest voltage/speed one could run the motor.I'll keep it for another purpose (perhaps make a small hand tool of some sort), but I'm getting a better 400W BLDC spindle instead of this for my cnc.

The motor has so much vibration under load in the 3018 prover that it is unusable. With the vibration the cuts are not clean. They make it sound good to bad it doesn't work.
