low RPM Generator
a larger, better working Version is available.
Created for test purposes, a finished version is for my wind turbine
http://www.thingiverse.com/thing:1718731
This version has three phases with serpentine winding but theoretically other types of windings are possible.
I used 4x4x15mm Magnets, because i had them here. 40 of these Magnets in a Halbach array arrangement.
First measurements With 50 windings (32 AWG Wire) on one Phase at about ~120 rpms:
3.8 V peak-peak, after the rectifier not enough for my application…
What you need
40x..............Magnets 4x4x15mm (Q-15-04-04-MN from Supermagnete)
1x................M8 screw or threaded rod
2x................M8 Nut
2x................608 bearing Ø22xØ8x7mm (e.g. inline skates bearings)
4-8x.............M4 screw an Nut
~1 meter......Wire per Winding (I use 32 AWG, from a microwave Transformer)
Print settings
0.4mm Nozzle, 0.15 Layer, 55mm/s Speed, no infill, no support
I use „CURA 15.04.06“
Assembly instruction
see Pictures
You can glue M4 nuts in the "Deckel 2x.stl". But make sure that the mounting screws are not too long.
If you have any questions or need further information, feel free to contact me.
Gerne auch auf Deutsch :-)
