HAND-WOUND BRUSHLESS MOTORS REVIVE GROUNDED QUAD

You’re happily FPVing with the wild blue yonder, dodging as well as jinking with the challenges of your preferred quadcopter racing course. You get a shade as well close to a branch as well as unexpectedly the photo in your goggles gets the shakes as well as your bird hits the dirt. then you odor the smoke as well as you understand what occurred – a damaged blade put a motor off-balance as well as burned out a winding in the stator.

What to do? A practical pilot may send the quad to the healing bench for a motor replacement. But [BRADtheRipper] prefers to take the chance to rewind his burned-out brushless motors by hand, in spite of the truth that new ones costs all of five bucks. There’s some madness to his method, which he demonstrates in the video below, however there’s likewise some justification for the effort. [Brad]’s coil transplant recipient, a 2205 racing motor, was originally wound with doubled 28AWG magnet cable of unknown provenance. He selected to rewind it with top notch 25AWG enameled wire, providing nearly the same ampacity in a single, much easier to manage as well as less vulnerable conductor. Plus, by diverse the number of turns on each pole of the stator, he’s able to change the motor’s performance.

In all, there are a lot of great techniques in right here to data away for a rainy day. If you requirement to get as much as speed on BLDC motor basics, inspect out this primer. Or you may just want to begin 3D printing your own BLDC motors.
