Stepper motors are great for their efficiency and high voltage produced with low torque. It is not always intuitive for the non-electrically-inclined to produce something a current that is more usable. In this video, I detail the workings of stepper motors, why they make better generators than brushed or BLDC motors, and how you can easily create a rectifying circuit using either 1N4007 diodes or the KPB-307 IC.
