Best of all, the entire package will only run you about $20 in parts–including the position sensor! “Another BLDC motor controller?” you might think. “Surely, I’ve seen this before“.

The latter approach is what [GreatScott!] settled on with his BLDC rewinding and rewiring project. Having previously explored which motors have the best potential as generators, he knew the ...

BLDC motors are often specified to maximize efficiency and torque density, and open rotor designs can further extend these capabilities.
