Low RPM Generator A larger and more efficient version can be found at: http://www.thingiverse.com/thing:1766551 This generator was created for testing purposes, but a finished version is designed for use in wind turbines, available at: http://www.thingiverse.com/thing:1718731 The generator features three phases with serpentine winding, although other types of windings are theoretically possible. 40 magnets, each 4x4x15mm in size, were used to create a Halbach array arrangement. The magnets are from Supermagnete and have the part number Q-15-04-04-MN. Initial measurements taken at approximately 120 RPM with 50 windings (32 AWG wire) on one phase resulted in a peak-to-peak voltage of 3.8V, which is not sufficient for most applications after passing through the rectifier. Required materials include: 40 x Magnets, 4x4x15mm in size (Q-15-04-04-MN from Supermagnete) 1 x M8 screw or threaded rod 2 x M8 nuts 2 x 608 bearings with a diameter of Ø22xØ8x7mm (e.g. inline skates bearings) 4-8 x M4 screws and nuts Approximately 1 meter of wire per winding (32 AWG, obtained from a microwave transformer) Print settings: Nozzle size: 0.4mm Layer height: 0.15mm Printing speed: 55mm/s Infill: None Supports: None The recommended printing software is CURA 15.04.06. Assembly instructions can be found in the accompanying pictures. When assembling, glue M4 nuts into "Deckel 2x.stl" but ensure that mounting screws are not too long.
