 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Bryan,and my other interested mates, this is the Exmork body and fron blade hub . I thought of attaching the disc to the rear of the blade hub and hydraulic caliper to the body of the exmork --plenty of room and I could also set the master cylinder with it's oil reservoir close by-I have all that gear. For those not quite understanding my project. The Exmork 's tail does NOT pivot, like our backshed and otherpower makes. Just the fin pivots . I've started this new thread as I feel it was getting away a bit on the microcontroller section .. If someone could bring all the other revelevent postings across to here , that may be appropiate also. again , thanks for your keen interest Bruce Bushboy |

Hi Bruce, Have not checked the electronics thread, but I have a pair of 1.5 kW 48V Exmorks that I am contemplating for a future project. Yours looks bigger, so I would guess that it must be 2 kW or more. When mine arrived they did not have any assembly instructions, but the Australian suppliers and Exmork were both quick to forward this information. Unlike yours, the 1.5kW ones that I have do not have an offset pivot, although the tail boom does have an angled pivot. This suggested that there should be some sort of furling scheme, although the tail fin appeared to be fixed to the boom, and I was blowed if I could see how their furling might work. The advice that I received from Exmork was that, because my units were pre-2011, I would have to tie a rope to the tail for furling. Maybe their latest pivot arrangements are offset, as is yours, so there could be some auto furling. As it happens, I am looking to set up a twin turbine arrangement, and did not need their furling system - just the alternators and blades, so a non-functioning furling system did not bother me. Hopefully, you will keep posting the progress of your project. Regards Don B |

Hi. Don B, mine is the heavy,say40Kg model. So I reckon she,a around the 2-3. Kw. Model Has the offset boom. Has the pivoting tail fin. I,ll let you know further developments when I get well,in hospital with problems ATM. Bruce. Bushboy |

Hi Bruce , Hope you get better soon and are back into it........ your Wind turbine Looks great , they are well built . As for fitting braking I have started a thread about Huaya exmork. I have put some info there that might be useful wit ID on what size you mill and what Huaya do to add brakes. Come for a drive over one day and have a look at whats happening on the other side of the mountain.

Imagine this disc and caliper mounted behind the Exmork blade hub . the disc attached to the blade hub and the caliper attached to the body --plenty of mounting points. Then the caliper's hydraulic hose to the brake fluid resevoir . That disc and caliper ,along with the hose ,hydraulic master cylinder and push rod came off one of those fancy italian motor gusi bikes, very strong and big ,so she should do the trick? There would be two ways of activating the disc brake. 1. A dc solonoid that operates the plunger in the master cylinder . 2. a pull wire through the center of the slip ring assembly down the tower to a hand operated lever or remotely activated solonoid lever /cam assembly to on/off the brake.

Hi Bruce, Sounds like you have a great plan in the making. Now I did find that test jig and can test it on a brake drum as I don't have a disk brake here. I reckon I do have a few solienoids here that will do the trick. Now tomorrow I will sort out a 3mm cube neo magnet and 1101 hall effect sensor and get them in the mail to you so monitoring rpm will be a breeze. Cheers Bryan |
