Bi-generator vertical wind turbine

cults3d

Generator/DcMotor and bearings required for this vertical wind turbine that uses 2 generators, - 12 bearings measures of (8x22x7) - 2 Hilitand 31ZY 24V/3.500RPM permanent magnet This wind turbine can generate more than 100 WATTS using this type of dc motors. It is very easy to assemble and if you print an array of this devices you can have a grid for domestic use or outdoors activity like in a camping etc. This wind turbine device is a part of a further open turbo-machine system based in a pending patent that contains not only open turbo-machines but also close turbo-machines ( jet engines, gas turbine etc etc) and as the picture show, we have developed a 2 stage VAWT where the top stage spins over an already rotating bottom stage making the top stage to rotate by itself and adding the bottom stage rotation. We are now developing a third stage, but in any case we are making a crowdfunding to obtain funds to continue with this and other innovative (In our humble opinion) wind turbine devices. This wind turbine systems have called the attention of 4 students from the Munich University of Applied Sciences and they have done a case study of it as a final project in their construction class. So if you want to discover more about this devices, please come to visit us in our pre launch campaign at, https://www.kickstarter.com/projects/459381052/multi-stage-and-generator-wind-turbine-system There is a step by step pictures attached to this post for making the wind turbine more easy to assemble viewing the pics *A new stl files has been updated with the name of ExtendExtensor.stl that consist of a turbine extension unit that can be linked with other extension units, so the turbine diameter can be extended more in case there is few wind available and you are using the 2 generators in the device. VERY IMPORTANT UPDATES It is important to mention that the type of filaments that must be used are different for each item of the device. For the none moving parts a PLA filament would do right and for the moving elements like gears or turbine blades the ideal filament goes from ABS, Nylon to poly-carbonate due to friction, wind etc. A new stl files has been updated with the name of ExtendExtensor.stl that consist of a turbine extension unit that can be linked with other extension units, so the turbine diameter can be extended more in case there is few wind available and you are using the 2 generators in the device. Another important update has been done. There is a new stl file that is a shaft linker between the small gear and another smaller dc motor (uxcell RF-500TB-12560 DC5V-12V 2300RPM-5600RPM) to be used in case there is not a lot of wind available therefor allowing the turbines to spin much more easily. The stl files have the name, *UpdateUxcell RF-500TB-Holder *UpdateSmallGearUxcell RF-500TB-ShaftLinker *SmallGearGeneratorShaftLinkerPerfectFit (There was an error in the diameter of the hole for the motor 31ZY shaft fit) It is fixed. NEW GEARS RANGE 3x1 If there is few wind as might be in cities etc, it has been developed a gear system 3x1 so the rpm of the motors shaft will be lower therefore taking less load. This is ideal for regions where the wind do not blow strong.This gear range system is applied to both dc motor Uxcell RF-500TB-12560 DC5V-12V 2300RPM-5600RPM & Hilitand 31ZY *SmallGearGeneratorRange3-1Linker *SmallGearRange3-1 *BigGearRange3-1
