This thing is still a Work in Progress

A small radial generator


Designed for my wind turbine
http://www.thingiverse.com/thing:1718731

This version has three phases with serpentine winding.
I used 10x10x40mm Magnets in a Halbach array arrangement.


First measurements (after the rectifier) 8 windings (0,8mm wire) on one Phase at 400rpm with a 500mA load: 5V
I had only wire for 8 windings :-) and my wind turbine does not rotate with 400 rpm.
...there are still more tests needed...

Update Parts: „Stator_1x.stl“ and „Deckel_1x.stl“
easier to print but fully compatible with old version

What you need

32x..............Magnets 10x10x40mm (Q-40-10-10-N Supermagnete.de, Supermagnete.ch)
1x................M8 screw or threaded rod
3x................M8 Nut
2x................608 bearing Ø22xØ8x7mm (e.g. inline skates bearings)
4-8x.............M5 screw an Nut
8x................M3x8mm screw / 3x8mm self tapping screw
1.3 meter.....Wire per Winding (I use Ø0,8mm, 20 AWG, from a microwave Transformer)

Print settings

• PETG Filament
• 0.4mm Nozzle, 0.20 Layer, 50mm/s Speed, no infill, no support
• I use „CURA 15.04.06“
• If you print with simplify3d set the extrusion width manual to 0,4mm.

Assembly instruction

• see Pictures
• Glue in M5 Nuts. Make sure that the mounting screws are not too long.
• You can cut M3 threads or use self-tapping screws for „Abdeckung Magnete 1x.stl“

if you have any suggestions for improvement, questions or need further information, feel free to contact me.

Gerne auch auf Deutsch :-)
