Vertical Wind Turbine by samrobmoe

Last crawled date: 3 years, 1 month ago

Now updated with MK3.1 - Which allows you to generate power!
A vertical turbine design which will turn freely in the wind, or when printing Base_Motor, you can use it in conjunction with a motor to generate power.
The motor used in my design is a 28mm diameter printer motor. If you decide to use a smaller motor, you could possibly print a spacer of some sort. You will also need to print the Arms_Gear and Motor Gear files, or if you wish to run a pulley system instead, then print the Arms_Pulley and Motor_Pulley files and find yourself an elastic band!
The Arms_Gear / Arms_Pulley files can be attached to the arms with 2 - 4x 25mm or longer M4 bolts
The turbine can be built in layers - I built a two layer version, as per the image.
The arms are printed in sets (Arms_Top & Arms_Bottom combine to make one set)
For a single tier turbine you need 2 sets, for a double tier turbine you need 3 sets, etc.
The design uses standard skateboard bearings and a length of 8mm threaded rod - I would recommend a minimum length of around 200mm for a single tier.
The Blades are held on the arms with M4 machines screws/bolts and secured with a nut on the other side - I would recommend at least 20mm length screws for a single blade, or 25-30mm for doubled up blades (Where the arm holds a blade on the top and bottom)

PLEASE NOTE:
The wind turbine must be firmly and securely mounted at your own risk. I am not responsible for any damages to property or people resulting from the turbine coming loose and/or breaking during use.
