Radial Generator II

thingiverse

This project is still a Work in Progress. A small radial generator designed specifically for my wind turbine can be found at http://www.thingiverse.com/thing:1718731. This version features three phases with serpentine winding. I utilized 10x10x40mm magnets arranged in a Halbach array configuration. Initial measurements (after the rectifier) showed 8 windings (0,8mm wire) on one phase at 400rpm with a 500mA load: 5V. Unfortunately, I only had wire for 8 windings and my wind turbine does not rotate at 400 rpm. There are still more tests needed to be completed. Update: September 15, 2016 - New parts added: "Stator_1x.stl" and "Deckel_1x.stl". These updated parts are easier to print but fully compatible with the original version. Required Materials: 32 x 10x10x40mm magnets (Q-40-10-10-N Supermagnete.de, Supermagnete.ch) 1 x M8 screw or threaded rod 3 x M8 nut 2 x 608 bearing Ø22xØ8x7mm (e.g. inline skates bearings) 4-8 x M5 screw and nut 8 x M3x8mm screw / 3 x 8mm self-tapping screw 1.3 meters wire per winding (I use Ø0,8mm, 20 AWG, from a microwave transformer) Print Settings: PETG filament 0.4mm nozzle, 0.2 layer height, 50mm/s speed, no infill, no support I use "CURA 15.04.06" If printing with Simplify3D, set the extrusion width manually to 0.4mm. Assembly Instructions: Refer to pictures for assembly instructions. Glue in M5 nuts. Ensure that 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, questions, or need further information, feel free to contact me. I appreciate feedback and responses in either English or German.
