The last few years have been amazing for the forward progression of military, commercial and recreational drone use. Improvements in battery technology have led to longer flight times, VR goggle technology has led to better precision flying with more detailed survey abilities and Vision Positioning has allowed for more controlled hovering flight. Along with these advancements, there are countless other micro-advances that are coming about as individuals and companies jump on board the UAV/Drone market to seek their piece of the booming industry.

However, you know the one area of improvement that has not been as skillfully advanced? The one area that a lot of people agree just can’t be improved, because it is inherently at its most efficient level. The electric motors powering the devices themselves.

We are CR Flight, a relatively new company based out of Nevada/California that holds patented and patent pending technology that allows us to proudly say, “Breaking News: CR Flight, a Nevada/California company, produces a new process and cool running electric motor that increases drone efficiencies by up to ~45% and on-demand thrust by up to ~200% over an equivalent standard motor.”

Someone needed to address the one component of a drone that hasn’t gone through the same series of incredible advances that the rest of the unit has in the last few years. We decided to take this hardware challenge upon ourselves.

To further explain, our technology is dubbed Counter-Rotating (CR) tech and it utilizes a clever natural variation of a typical single motor, single propeller application. In a typical single motor design, there is a stationary stator that then powers the rotating rotor that has the propeller attached to it; the outcome is thrust and lift for the drone. We thought, well why let all of that energy be wasted into the stator as the counter force to the propeller spinning? Can we utilize that wasted energy in any way? Turns out yes, yes we can! And with surprising outcomes.

Now applying our technology, we have suspended the motor on a slip ring assembly that allows both the rotor and the stator to rotate while electricity still reaches the spinning field coils. And as the technology’s name implies these two units “counter rotate” around each other in opposite directions and utilize the previously unused energy that was being lost to heat/friction in a normal electric motor system. Both the rotor and the stator now have propellers, which allows for a combined thrust force much higher than that of a typical single propeller motor.

The upper photograph is a CR Flight modified motor that began life as a standard KDE Direct motor (~45% less power draw for the CR Flight modified version compared to the standard KDE Direct motor at equal high thrust). The lower photograph is a CR Flight modified motor that started life as a standard RC-Timer motor (~30% less power draw for the CR Flight modified version compared to the standard RC-Timer motor at equal high thrust). Both CR Flight modified motors operate at dramatically lower temperatures.

You may say, “Well, I can just solve the same problem by using two motors back to back and add those two up with the same outcome.” Sure, you could do that but at a huge cost. The power you gain for the energy expended does not even come close to the efficiencies that our motor produces. I keep mentioning “efficiencies.” What exactly does this mean? There are, of course, a wide range of categories that could fall under.

To be more precise, CR Flight provides a cost effective solution with our technology. Through rigorous testing, our CR motors provide up to 200% increased thrust when needed, provide 15 to 45% longer battery life, and have an operating temperature that is one-half that of a comparable standard motor. These astounding results are just that, astounding. We would like to see these motors in any and every drone, if possible. Nothing short of an incredible improvement on standard electric motors is what we are offering.

Herein lies our main hurdle as the CR Flight motor is a victim of its own success; by tapping into a new process by which to run an electric motor we open the door to sceptics. Countless times we have run into engineers that insist that what we offer simply “can not exist.” Being anchored in a certain mindset, however, is a dangerous way to help the forward progression of this industry. So, with that we say, “Sceptics and critics one and all, we welcome you to CR Flights motor technology, these electric motors are the future and salvation for more sustainable drone flights and we encourage your scepticism, for with your feedback we can continue to perfect our motor and help supply the best product to this exciting drone industry.”

Therefore, we put forth a challenge to drone companies to prove our CR technology: “Give us your current motor and we will modify it with our CR technology and return it to you for your testing!”
