Introduction: Stepper Motor Generator

This instructable goes over how to create a generator to power lights, charge a battery or capacitor, etc. with kinetic energy.

Stepper Motor (with 4 cables)
8 diodes
a load to charge or power

Step 1: Create a Bridge Rectifier Using 8 Diodes in a Diamond Formation

Here is a project that I created using this circuit:

Circuit Board (A board that lights up using the kinetic energy of the spinning wheel)

what type of diode are u using

aizat0904 (author)2016-09-24

is this stepper motor can be use?

What is the com link? And real photos I can base this off of? I'm a little new to cicrurtry, and I need help sooner than later

SkyRanger (author)SkyRanger2015-12-08

Just did a little research. It's an inductor and the other thing is a capacitor. Specs on those?

Sky Ranger - in the circuit diagram the coils on the left are the actual stepper motor. It has two sets of windings (coils) and 4, 5 or 6 wires - com stands for common which is a centre tap on each of the windings and in this example is not being used. Although he shows capacitors in the circuit diagram I cannot see any on the breadboard, and there are none mentioned in the parts list. Make sure you connect the diodes the right way round, they are marked with a line or spot on the negative side. They only allow current to pass in one direction (not the cheesy boy band!) so if you get them wrong the circuit will not work.

Made it. 390 rpm, 3V, 6mA. Good lighting.

What are the values of the capacitors you used?

JohnC386 (author)2016-06-03

is the stepper motor used for arduino capable of doing this? this is what it looks like:


StudentBuilds (author)JohnC3862016-07-02

Yeah it should be fine

minimeccanica (author)2016-02-26

Any figure about the V and I you have drawn?

chadeau (author)2013-03-13

Just what the Doc ordered-do you have specs on diode and capacitors? Thanks...

1N4007 is great

nerd7473 (author)2014-04-26

how do I do this with a prototyping breadboard?

nerd7473 (author)nerd74732014-04-26

not the solderless

RedstoneM (author)nerd74732015-06-07

Simply solder it? (solderless ones are better from my opinion)

Thanks, I've been meaning to get a windgenerator project going sometime in the future. I have some leftover steppers left. *added to favorites*
