Make a BLDC Motor From Scraps You Can Find In The Garage

Think you’ve got what it takes to build a homebrew brushless motor? As [JaycubL] shows us, it turns out that a bldc motor may be living in pieces right under your nose, in scraps that so many of us would otherwise toss aside. To get our heads turning, [JaycubL] takes us into the theory of brushless DC motors operate. He then builds a homebrew brushless motor using screws, a plastic container, a few bearings, a metal rod, some magnets, and a dab of epoxy. Finally, he gives it a whirl with an off-the-shelf motor controller.

This isn’t [JaycubL’s] first dive into homebrew brushless motors. For the curious, he’s also assembled a fully-functional brushless outrunner motor with a paint can housing.

Sure, understanding the principles is one thing, but being able to take the leap into the real world and find the functional beginnings of a motor from your scrap bin is an entirely different story! [JaycubL’s], dare we say, finesse of understanding the principles behind motor design makes us wonder: how many other functional higher-level electrical and mechanical components can we bootstrap from bitter scrap? To get you started, we’ll point you in the direction of this CNC router that’s just a few steps away from one trip to the hardware store.

Thanks for the tip, [John]!
