Hi ,
Thought I would throw a few pics of my latest mill I nic named " THE BEAST " . It is set up as 2 x 60s and 2 x 80s all unmodfied stators in delta , each has its own rectifier in parallel . Recently on my good wind days I have been watching my dual with 3.2m dia blades hitting 520 rpm and with the piclog data max power is at 350rpm for both 60 & 80 series and the cut in is 100rpm for 60s - 145rpm for 80s reaching max output 450w @ 400rpm for 60s and 550w @ 400 rpm for 80s , so I came to the conclusion I am powering a golf buggy with a V8!!
Anyway I can now alter cut in rpms by different stators / star delta / etc , basicly staggered stators with a potential output of 1kw with out the downfalls of neos which in my experience with them require to much start up force and come on to quick stalling the blades . With this set up I could for example have 4 different cut in speeds - 60 star @ 65rpm , 80star @ 87rpm , 60 delta @ 105 rpm , 80 delta @ 145rpm , but for first I am going all delta as my blades seem to start performing at 80 to 100rpm . Hopfully this will keep a gradual load on the blades to stop the over rev which is what I think is the cause of noise and failure in high winds.

Also by carefull alignment of the stators and rotors I have been able to reduce the clogging to a minimum , but there is more magnetic and mechanical drag to deal with . While sitting here it has just started for the first time in 13 to 14 k puffs and kept running in 8 to 10 k , which is promising .

Hopefully I haven't sacrificed to much of the low wind peformance I was starting to get with the dual 60s , but time will tell there and that definatly will be a down side .. The other down side is the head weighs in at 32kg add another 33kg for the pivot, tail and bump start blades and hub and thats why its called " THE BEAST "



Luckly I have a big strong 18 year old son to help me lift this on or I would have had to build a crane to lift it on!!!




Blades on and ready to see if the tower will bend..




Another pic just in case it ends up a twisted mess on the ground!!!




Going up , pole is handeling the load but is flexing a bit...




Up and waiting for wind !!!

Phil,
I was going to complain at your using "The Beast" as that's what I call my dual rotor, but looking at those pics I must concede yours is more deserving of that name than mine. Bloody Hell it's a big brute!!!

Great work. Looking forward to good reports when the wind blooooooows.
was working fine... til the smoke got out.

You have too much spare time Phil.

It is impressive.

Sorry I doubled up on the name Gill , I could re-name it " THE F!*#ING HEAVY BEAST " .. And all my spare time is over now Glenn , I resigned from up in the mines last week , next week I have to finnish of a major landscape project here at home and then start back at Komatsu building 49 x 240 ton rear dumps for the new mine at Clermont , good-bye to days pottering arround in the shed , so I took the opportunity to throw that together over the last couple of days as it's been in the back of my mind for a few months ..

Phil,
at first glance it looked to me like whence it came from.The AGITATOR.What a magnificent effort in utilization.Would next time it's taken down deliberately, could we have an exploded view of its assembly.Looks like it could handle a second blade set out of phase on the other end.And taking that a step further these then downwind blade's could potentially balance the gyroscopic forces of the front set around the pivot.But as more shaft overhangs behind the pivot the downwind blades could potentially generate enough lateral force to do the wind tracking and eliminate the tail.Just an observation from an amateur.Well done.

Great stuff! Is the tower made of 65mm OD pipe in the lower section?

Son of a B*@% that's impressive !!

Very nice work Phil. Considering I have a collection of
F&P's, I'll be starting with a single rotor & stacking as
I get confident. Now that someone has tried it, I feel
much better.

wow very impressive, a lot of weight up there.
are they all decogged stator and old rotor or new 7 phase units,
great work well done

Good stuff Phill,,,
Those 2 white rotors--they are the original type ?? maybe sometime down the track try all grey rotors as all the tests I've done with those white rotors show them being the weakest ?( and the most noisy ) Maybe ?

Nice job ,mate, a complete rebuild by the looks of the tail ?.
You might get the prize for the first 1Kw F&P ?.

Hi Trev,
Still not a lot of wind but we have had a few blows that the piclog catches the data , as Kim turns it on if the wind starts as I am now working in Brisbane , anyway here's some figures that look promising
RPM - Watts
105 - 3 - cut-in
117 - 45
126 - 63
140 - 106
162 - 240 - 80series stators cut in @ 145rpm
186 - 405
218 - 569 - wind speed was 28 klm
It definatly takes 12 klm to start and will keep going in 8 to 10 klm as long as it gets above 50 rpm , can't wait to see 30 to 40 klm , hope fully sooner rather than later. Would love to trial a set of your big blades on this gen . I'm also thinking of knocking up another 3 blades and trialing 6 blades to improve the low wind output as by the look of the data so far by 300 rpm I should be getting close to 1Kw . Time and wind will tell..... Phill

Hi Phill,,

Very impressive,, we are having peaks of 50+ Kph here ,,and the mill is going ape,,with the electrical brake on she is under control up to about 30 Kph ,,but over that ,it just goes bonkers ,but still furls...

I hope it survives tonight,,10 hours to go...

Hi Phill,

I have plotted the data, you presented.


The graph does appear to be quite linear. This is not what I would have expected. This may be caused by some relation between the iron and rotor. Good output whatever the case.

I will be bringing my cct bits to QLD, with some rewinds to be tested at Bruces. Good luck tonight. Gordon.

It got cut up and never revisited. I got the best performance with the duals with the right combination 80S + 100S Twisted poles with the GOE222 blades it was the best F&P for all round conditions.
