If you’re looking for a modern motor, with everything you could possibly desire, this is the one.
We made this motor because, well… To be perfectly honest, we wanted our very own motor. More importantly, though, we wanted our own motor because we wanted a motor that had everything, no compromises. Read on to find out why we believe that these truly are worthy of the name:
“The Motors.”
Now, we’re aware that there are already quite a lot of nice motors out there, but when you really look into them we find most of them fall short somewhere. Be it garish design, an outrageous price, or a missing feature. We felt that we could do better and we genuinely feel that this motor gives you everything you could want, including very high quality, at a reasonable price. It is also our very first 100% custom motor, and we hope that you will enjoy flying it just as much as we do – it’s a blast! If you are sold already and willing to give the motors a go, you can pick yourself up a set here. Otherwise, read further to learn more about just why “The Motors” are the way they are.
Why 2208?
Why not? More seriously:
Currently, 2207 and 2306 motors are some of the most popular stator sizes for FPV flying, and they really are great. However, new motor releases are being released with a trend towards taller stators, 2207.5 for example, as the extra height gives the motor just that much more torque with often negligibly more weight. So, we decided to commit and go full 2208 stator size. The additional torque this grants gives you the precision you want when racing through gates, or the control you need when trying to do that perfectly timed proximity stall (after a matty flip, through a keyhole, of course 😎). To offset the extra weight, the top of the bell has been designed to look awesome, remain strong, but keep as skinny and lightweight as possible. As with most other modern motor releases, our motor is a “naked bottom” design, which aids with both cooling and keeping the weight down.
Clean and Tidy Aesthetics
The design language we used on the motors can be summarised as neatly understated, classy. We went this route to make a tidy looking motor that’ll suit any build very nicely. This means we’ve opted out of any garish colours, and have focused on some of the smaller things, such as neat, solid core windings, for a super clean finish overall. We find that if you fit black props to The Motors, the end result will look sweet and stunning on any carbon fibre frame, an estimated 100% of the time. The bell design, if you look closely, is fashioned around the Unmanned Tech squiggle logo, which was a subtle personal touch from us that we’ve grown rather fond of, and when you see The Motors in person, we’re sure you will too!
Materials, Magnets, and Magnificence
Being top-of-the-line, 7075 Aluminium is used for the construction of the bell, an aerospace grade aluminium that has a strength comparable to steel. It is a tad more expensive to use than some alternatives, but given the skinny bell design we felt it important to use to keep the motor strong, which it does very well. Additionally, The Motor uses a titanium hallow shaft, keeping in line with the previous material choice reasoning.
Inside the bell, we use N52SH magnets, which are the strongest type of Neodymium magnets you can currently get in a brushless motor. The SH is related to the operating temperature, and our magnets can work at up to 150 deg C before they start loosing any of the magic magnetic force, not that you’ll be able to get The motors up to that temperature! On top of this, they are arc magnets, which minimises the air gap between the rotor and the stator – this is key to the motors impressive performance.
The Coils
The coils use single core wire which not only looks nice and neat, but more importantly, has a wider operating temperature range which again increases the motors’ durability. The actual core of the stator is made using super tiny 0.15 silicone steel sheet lamination, resulting in reduced magnetic losses. As you may have figured out by now, this is in the interest of increasing motor performance – a common thread in all of our design decisions.
Smooth, slick Bearings
Meticulously choosing all the best bits to use on/in a motor would come to nothing if you neglected to have bearings that can handle everything thrown at them. So, with this in mind, we’ve decided on NSK precision bearings – smooth, slick, and sturdy, some of the best we’ve used. As well as this, we also use slightly larger-than-usual 9mm bearings, which work much better when squeezing every bit of performance out the motor is your end goal, which it was in our case.
The Buttery Biscuit Base (tasty!)
Finally, we reach the base of the motor. Here, we opted for the naked bottom approach (as previously mentioned) as it is both lightweight and helps to keep the motor cooler. We also decided to include a sort of “retaining bar” for the motor wires, as this stops them getting accidentally caught by the rotor when you are mounting it – a semi-common quad building pain, but one that need not happen again. Lastly, we of course include a screw to secure the bell to the stator instead of those pesky, fiddly c-clips. This means that if you get some mud on your motor (which is very common here in the UK), it’s a lot easier to remove the bell for cleaning/replacements. But be warned, the magnets are, as we said, super strong – so don’t get your fingers caught when putting the bell back in place!
Now go and buy a set so we can keep the lights on!
Aaaaannnd that just about covers it! Here at Unmanned Tech, we have put a lot of hours into making this the best possible motor, and we sincerely hope that you enjoy flying The Motors as much as we do. Being a TheFPV product, you know that we will have your back if the motor is not up to scratch. Thanks for reading and see you out there!
