Over the previous decade or so, drones have gone from relatively unique flying machines, used and constructed by a choose few, to one thing that many individuals use for a variety of functions. Nonetheless, some are extra devoted than others to this pursuit, together with YouTuber Constructing with Logan. He particularly enjoys flying five-inch FPV freestyle drones, however determined that he wished to additionally get into the comparatively gigantic one-meter class.

Somewhat than merely shopping for 4 brushless motors and strapping them onto a body with batteries and management {hardware}, he as an alternative determined to constructed the motors themselves from scratch. His preliminary motor design makes use of a 15-coil, 20-magnet configuration, giving a three-to-four coil-to-magnet ratio, which seems to have stayed the identical throughout the construct course of. Nonetheless, many components of the design, as outlined within the construct video, have been revised throughout improvement.

The primary prototype, with coils wrapped round a 3D-printed core, is seen on the 4:00 mark. It spins means too quick, with too low of a torque output for use in a one-meter drone with massive propellers. The answer was to interchange the 3D-printed core with a set of ferrous plates, which once more needed to be wrapped with wire – and wrapped but once more after including enamel-based paint to stop shorts. An outer “again iron” shell was additionally added to additional improve magnetic efficiency, finally producing six kilos, six ounces of pressure, exceeding Logan’s challenge objectives.

Logan additionally designed a hub and propeller meeting, and was finally capable of produce 4 of those motors for future droning. Now the one factor left to do is construct and fly the one-meter drone itself!
