Oz Ax Wind Engineering.

Complete windmill kit.

Hi All

For someone just starting out with wind generators it all might seem very daunting as it was for myself over 2 years ago when I first discovered this web site. I started with the F&P Smartdrive as my alternator and a design I came up with to easily mount 2 stators using the original bearing housing, a design that has not changed very much and has proven it's self through many a blow.

What I have refined is the chassis ( nacelle ) , blade hub ( collet mount ) , tail and pivot. All this combined with the aluminium blade system that Glenn had a major part in designing has lead too where the "dual" is at today. I have always been in the belief that if you are going to go to the lengths to put a windmill on a tower then why put one stator when 2 is just as easily achievable and doubles the output. The components are all shown below in the pictures and are available individually, partly finished or as a complete mill.

As development of this design continues, eg, I get another brain storm, changes are made and always for the better.

I have decided to call this little back yard business Oz Ax Wind Engineering, the eventual direction that I plan on heading in. At present I am designing a kit based on the axial flux generator that I recently built which will be called Oz Ax 300 ( 300mm diameter alternator ) and also a larger Oz Ax 400 ( 400mm diameter ). These should only be considered by those who can use the large amount of power generated by this type of generator, but dollar for watt they are the winner. Hopefully this will become a reality within the next few months and I'll update this page as news come to hand.

I still consider all this to be a hobby and doubt it will make me rich beyond my wildest dreams, the amount of work that goes into making these components far out weighs the price and is only suited to a few as most here prefer to DIY but do not have access to expensive machining facilities. I have tried to come up with components that are strong, simple, and easy to machine with my resources and time. Below are some links to some of my pursuits over the past...

• 4 Stator - 48 v - " THE BEAST "
• Homegrown - Ax Fx
• ALUMINIUM BLADES UP - NEW HUB & TUBES
• TESTING BLADE STRENGTHS & FORCES
• Oz-Ax-Flux 3 Kw +
• The "Ax Fx - & - F&P Dual"
• Testing Capacitors

Complete dual stator kit.

Fixed Shaft Blade Hub

A. 10mm steel disc
B. Collet locks hub to shaft and compresses front rotor to shaft when tightened.
C. 12mm bolt threaded into standard F&P shaft.

A. Rear magnet rotor is standard and uses standard F&P spline.
B. Front rotor is modfied and blade hub then locks the whole assembly to the 25mm shaft, keeping it rigid and strong.

New blade mounting system. Above is the solid steel inner, stainless steel outer and mounts. Below is the hub with mounts attached..

A. 1inch UNC mount stud and nut.
B. 2 of 6008 sealed yaw bearings.
C. 22mm hole through the bearing assembly to allow for wiring 2 of 15amp leads.
D. Housing is 75mm heavy waqlled tube prepared to be welded to your tower.
E. Adjustable tail offset stop.
F. Tail mount to suit 50mm box aluminium.

A. Assembled with aluminium tail. Tail can be easily built from 50mm aluminium box and aluminium sheet.
B. Fine adjustment to the furling speed can me made by changing the blade offset.

DIY Dual Stator Bearing Assembly. Ready to attach to your own design.

Basically this is what you need to get a dual stator up and running.

1. Bearing Assembly.
2. Modified shaft and front rotor.
3. Collet Blade hub basic ( no shafts ).

Bearing Housing and arm mount. The original F&P bearing housing is press fitted into its housing.

Add one of Trev's nose cones to give a professional look.

I can also supply extruded aluminium blades.
