Due to many requests we have decided to offer a complete axial flux wind turbine. This machine is ready to go on your tower top with the exception of a little wood finishing and a bit of assembly. The machine is of our own design but very similar and very much inspired by Hugh Piggotts designs. The machine is manufactured here in our off grid shop mostly with wind and solar power. We have been building this basic design now for 5 years. With many machines now in the field we feel the bugs are worked out and we feel confident offering them for sale. Several of our machines have survived 3-5 years in the field with no problems and no maintenance (although we do recommend yearly maintenance).

Included is the assembled alternator, blades, tail vane, all necessary hardware to assemble the machine, and a USERS MANUAL. All that remains for you to do is apply finish to the wooden parts (blades, blade hubs and tail vane) and assemble the turbine. You will also need to provide your own tower, 3 phase rectifier, diversion regulator and all other parts of the system. This machine is designed to charge batteries, you need to specify when you order if you want it setup for 12, 24, or 48V.




This is a 10 foot diameter turbine conservatively rated at 800 Watts, although the alternator has proven to withstand sustained output of 1000 Watts in bench testing. The blades are beautifully hand carved from Western Red Cedar, they are the same blades we sell here. All of the holes are drilled in the blades and the hub so assembly is simple and straight forward. Once the blades are finished, and assembled - you will need to balance them on the wind turbine.



All of the metal work is powder coated. When we build the machine, we first powder coat the magnet rotors and all the rest of the metal work. We put 12 2 inch diameter x 1/2 inch thick magnets on each rotor and then band the rotors with stainless steel and cast vinyl ester resin mixed with alumina trihydrate and chopped fiberglass around the magnets. The alternator runs on a common trailer hub which utilizes very common/inexpensive tapered roller bearings.

The stator in the machine is the same HD(heavy duty) stator that we sell here, again - you will need to specify your system voltage when you order. This alternator will usually slightly overpower the blades (Stall) and if the machine is very close to the batteries you may need to add resistance to the line to match the load to the power available from the blades. The machine furls to the side in winds over 25 mph limiting the sustained output to about 800 Watts. You can add a bit more weight to the tail if you require more power in higher winds but we prefer to keep things slow and cool running. Most of your energy is available in lighter/average winds so we don't get so worried about 'peak' output.




A wind power system is a significant investment so be sure that you realize what you are getting into before you get in too deep. We have a Users Manual that you can either buy here, or down load free HERE. You should read this users manual before you buy - it contains a lot of useful information about the machine and the rest of the system. Hopefully if you are considering this purchase you have a good understanding of renewable energy systems, wind power, and the basic design of this machine. If you do not have a good understanding of this stuff, please take some time to read our Otherpower.com website. Check out Dan Finks articles HERE, HERE, and HERE. And again - be sure you either purchase, or download the USERS MANUAL before you buy.

This item ships in 3 boxes, it is large and heavy. It will usually ship via UPS ground and at this time we will only ship the complete wind turbine kit to the US or Canada. If you are not within the US or Canada please email us before you order and we will discuss shipping options.

We build these to order so please plan on 2 - 4 weeks for delivery.
