Works great. Better than original 300w

This spindle motor has a couple nice features that many router motors do not have. I had to go back and check the product description because I failed to note the features when I bought it, and although they do indeed mention them it's not like they are bragging them up in marketing hype. First and foremost is the fact that this spindle motor has effective torque sensing feedback in the drive circuit that tries to maintain constant motor rpm under different load conditions by sensing the load (probably by the current draw) and adding power to keep the motor from bogging down. All of my other routers (mostly older models) are entirely open loop and if you use an external speed control to keep the unloaded rpms down they will bog down as soon as you start cutting. The NymoLabs motor feedback may be a little slow-acting, but under fluctuating conditions it really pours on the power under increasing load to try to maintain rpm. The rpm will overshoot a bit if you suddenly decrease the load, and slow a bit then overshoot if you suddenly add load, but over the course of normal use the set rpm will be maintained quite effectively. The product description indicates 6 speeds, but this is likely taken from the dial scale which has no correlation to the actual discrete speeds. Speed control is not continuous but has 11 speed steps ranging from about 6000 to 30000 rpm, give or take a little. The speed indication does appear to be attempting to display actual speed (and not simply "set" speed) because it does fluctuate under load, but the display resolution is rather coarse and only increments for fairly large rpm changes. The torque feedback of the motor actually makes the displayed rpm a little difficult to test because trying to slow the motor by applying a load to the spindle with a leather glove results in very little audible or visible speed change. The motor has a short wired-in cord (see first photo) with a receptacle that accepts standard instrument power cords, something that I would like to see for all power tools. Locking power cords are readily available so they won't pull out and having them detachable on multiple power tools would make storage much nicer. The motor is very smooth and vibration-free in operation at all speeds with no resonance anomalies. As shown in the last pictures I am holding this motor alongside the smaller 1/8" collet DC motor that I intend to replace. This is attached to the head of my CNC mill, offset to the left of the main spindle. I use this mill for both metal and wood/plastic and I need to have the high-speed spindle for routing and engraving tasks. I think with a height-adjustable baseplate this would also make a pretty nice trim router. I have one of those small Bosch trim routers that is about the same size, and while it has soft-start I don't think it has any torque-sensing like this motor has. Comes with two extra pairs of brushes too. It seems like a pretty nice motor for the price.

Im not sure if it can speak to quality i.e. best spindle ever. But I will say it a 1000 times better than a Makita router. What makes me say this is the sound. This is so quite that now I'm mad a my dust collection system for being louder. Some things to consider: the speed control is touchy and you will need both wrenches as it doesn't have a push button to lock the head. Other than this, I'm not sure you can do better for the price.

So far I am impressed with the quality of this CNC spindle motor. This is essentially a specially designed version of a trim router tailored for CNC use. Unlike a standard router, you get CNC engraver precision, ER11 collet, a long modular style power cord, digital real-time speed display, soft-start and constant torque technology, long life brushes and stable operation. Installation: They've designed installation to be very simple. The spindle has a body diameter of 65mm and it works with most spindle mounting brackets and is similar in size to most trim routers. The engraved depth markings on the spindle body are convenient for repeatable mounting height. The power cord included with the Nymolabs spindle features a length of about 11 and a half feet which is more than enough for most setups. The spindle itself has a short power cable that plugs into a standard PC-style power cord. If you need to replace the cord or swap cord lengths it is incredibly easy thanks to the power cord's modular design. Function: This spindle works very well in my experience. There's less radial runout than my old spindle and this seems better suited for precise work than many actual wood routers I've used. I love the adjustable speed display and it is the main reason I picked this up. Having a real-time indicator instead of guessing, listening or relying on less than ideal external tachometer solutions is a nice bonus. Speeds of 7,000 to 30,000 RPM without the deafening roar of most routers is a nice quality of life improvement. The fact that this spindle uses a closed loop speed control instead of a "dumb" triac dimmer circuit without feedback (or worse yet, nothing at all) is a welcome bonus. I consider this a trim router that has been refined for light to medium duty CNC work. It bridges the gap between an underpowered feature less air cooled DC spindle or old school handheld router and much more expensive solutions. While it may be less powerful than some actual trim routers, it is also: more affordable, less noisy, more precise and feels better suited for smaller precision work in lightweight material. Essentially they took a palm trim router design and refined it for use on a CNC engraver/router. For a lot more money you could step up to a bigger spindle yet with liquid cooling and a VFD. That's not the intended buyer. For a little more money, you could get a more powerful handheld trim router. Whether that is the right move for you depends on your intended use. There really isn't one perfect solution. A more powerful trim router might be better suited for brute force applications where you're throwing around large diameter bits and working with tough material. The Nymolabs spindle attempts to offer a best of both worlds or middle ground approach. It trades torque and power for features and precision that make it more suitable common CNC router work. Compared to a more powerful trim router it is smoother, more balanced, has less vibration, offers finer run-out specs, more precision and features better speed control. I personally have both in my lineup. If I need more power I can simply swap out heads and get to work. In my opinion this spindle offers great value at its affordable price point. I'm happy to have it in my lineup and would order again.
