Hi Billo,
Sorry my delay. I have been busy with Christmas and work. Most of your dimensions are the same or similar to mine since we both looked at Fabi's as a starting point. Here are a few that differ slightly.
On the upper platfrom:
You have 180, I have 203
You have 594, I have 508
On the lower control arm:
You have 40, I have 80
On the connecting rod:
You have 630, I have 609
Some of the other numbers will change automatically once you start placing in the new numbers if you choose to use them. There is flexibility here Billo. I tried to be as exact based on what was given as dimensions. You will place your dimensions into the software which will calibrate based on your numbers. You have a great starting point. Some of my numbers changed during my final settings when I was assembling, especially the height of the connecting rod. It started at 630, but when I adjusted the HEIM joints, it unded up at 609. I also worked in inches so I had to convert all the numbers from metric to inches. Feel free to use my dimenisions if you like. You will be very happy with your results. If you need anything else, please let me know.
Good Luck and Merry Christmas!
Steven

Grazie infinite Stevant per la verifica...effettivamente ho nodificato il disegno con le tue misure e la differenza è minima ma almeno vado a colpo sicuro. Devo decidere per qualche dettaglio sulle teste a snodo ma ormai posso dire di avere il progetto pronto per la costruzione  ecco il risultato Nel frattempo sono già arrivati gli inverter rimediati a sole 80 euro l'uno   Ora inizia la caccia ai motori, posso chiederti quanto sono costati i tuoi e se li hai presi online? Thank you so much for checking Stevant it.... actually I modified the design with your measurements and the difference is minimal but at least I'm going to fail. I have to decide for some detail on the rod ends but now I can say to have the project ready for construction. here is the result. Meanwhile are already remedied inverters just 80 euros apiece. Now begins the hunt for engines, can I ask you how much your cost and if you have taken online?   |

I bought my motors at Automationdirect.com. for $125.00 USD a piece. I also bought my Gear boxes from them for $241.00 USD a piece. The gear boxes need a 2.62 base which cost $24.50 a piece.
Motor: MTR-001-3BD18 1hp, 3 phase
Gear Box: WG-262-060-D 60:1 ratio
I bought my inverters at Driveswarehouse.com for $224.00 USD a piece.
Inverter: Hitachi WJ200-007SF
Let me know if you would like to know anything else. The motors and gear boxes are not the prettiest since they are black and not as sleek as some of the other ones, but I knew mine were going to be covered so I did not mind as they work well for me.
Ciao,
Steve

 grazie stevant per la velocità  Sto cercando di creare un simulatore di qualita ma cerco di stare attento ai prezzi perchè qui tutto si moltiplica per 6 ed esce sempre fuori una bella cifra. Con gli inverter ho avuto fortuna: Sono 6 omron 3G3MV-A2007 0,75 Kw una rimanenza di magazzino, quindi nuovi a 480 euro (80 a pezzo)   Ora sto cercando di capire quale sia un buon prezzo per i motori...forse prenderò qualcosa online ma qui in italia altrimenti la spedizione dall' estero mi alza troppo il totale anche se i tuoi motori mi piacevano. Intanto ecco qui i miei bambini Thanks for the speed stevant;) I'm trying to create a quality Simulator but I try to be careful because prices here everything is multiplied by 6 and getting out a nice figure. With the inverters I got lucky: Are 6 omron 3G3MV-A2007 0.75 Kw a remainder of stock, then new to 480 euros (80 to piece) now I'm trying to figure out what a good price for engines ... maybe I'll get something online but here in Italy, otherwise the shipment from abroad I raise too the total even if your engines I liked. Meanwhile here are my kids  ![]()  |

grazie stevant, però non posso copiarti tutto  quindi almeno per l' elettronica avrei pensato a un altra sistemazione: cosa ne pensate? Boun Naltale anche te Thanks stevant, however I can not copy everything to you then at least for electronics I thought another accommodation: what do you think? Merry Christmas also you  |

Hi Billo,
I was going to put all of my electronics below my platform like your picture shows but I decided against it. I felt it was not safe. If you need to make adjustments to your inverters the last place I wanted my body was in the middle of this powerful platform that could crush you if it moves while you are underneath. It makes sense to save space but I felt it was safer to have outside of platform so you can adjust while it is on.
My 2 cents.
Safety first!!

Grazie stevant del prezioso consiglio, non ci avevo pensato Quindi ho fatto diverse prove con il modello 3d nella staza dove andrà posizionato ma purtroppo non ho altro spazio e già così devo fare parecchi spostamenti. Sono quindi costretto a tenere l' elettronica sotto, fortunatamente in questo modo dovrei poter accedere ai miei inverter dagli angoli della base (vedi foto) quindi senza dovermi mettere sotto la piattaforma. Forse la cosa più scomoda alla quale arrivare sarà la AMC1280USB perchè la vorrei posizionare al centro. Capita spesso di doverci mettere mano? Già che ci sono volevo togliermi un altro dubbio: Con il traduttore online molte cose sono incompresibili, ho capito che gli inverter vettoriali sono migliori rispetto a quelli V/F e i miei possono essere utilizzati in entrambi i modo. Non sono riuscito ancora a capire se devo prendere dei motori particolari per gli inverter vettoriali o se vanno bene i semplici motori trifase asincroni. Sto trattando per acquistare i motori e vorrei essere sicuro di non sbagliare  Thanks stevant of valuable suggestions, there I had thought So I did several tests with the 3d model in the path where will be placed but unfortunately I do not have more space and already so I have to make several trips. They are then forced to keep the electronics underneath, fortunately in this way should be able to access my inverter from the corners of the base (see picture) then without having to put under the platform. Perhaps the most awkward thing to arrive will be the AMC1280USB because I would like to place in the Center. Often having to put out? While we are wanted to take another doubt: With the online translator many things are garbled, I understood that vector inverters are better than V/F and can be used either way. I could not even figure out whether I should take special engines for vector inverters or if they go well the simple asynchronous three-phase motors. I'm trying to buy engines and would like to be sure not to miss  ...e tanto per gradire questa è la postazione già pronta che ora uso per i 2 dof ... and so much for liking this is the workplace ready now for 2 dof  |

In attesa dei preziosi consigli ho affinato un po' il progetto dedicandomi al quadro elettrico. Raffredderò gli inverter con 3 ventole da 120 mm mentre le zone rosse nel coperchio sono fatte con lamiera forata per permettere all'aria di circolare per bene. Pensate sia sufficente? Le ventole secondo voi lavorerebbero meglio aspirando o soffiando? Ho cercato anche di curare un po' l' estetica ed ecco il risultato Waiting for valuable advice I've aged a little addicting to the project Panel. to cool the inverters I thought 3 120 mm fans while the Red areas in the lid are made of perforated to allow air to circulate well. Do you think is enough? The fans do you think would work better sucking or blowing? I tried also to cure some aesthetics and here is the result     |

Hi billo,
What is for me peharps more interestning is to cool the motors .It depends how there are powerfull and how much percent from their power you need to move the platform.
Normally Inverters have their own cooling system , just be sure that they get enough air flow.When I look your design there space around them.
The question is for me motors because their cool fan is not used as they supposed to be .Always the motor direction changes during motion

Ti ringrazio per il suggerimento. Sto pensando di smontare la ventola originale dei motori e applicarne una io con alimentazione esterna a 12 v.
Credo sia il sistema più economico e allo stesso tempo valido.
sei d' accordo?
Inoltre mi è stato consigliato visto che userò la AMC1280USB di ridurre la distanza tra gli attacchi della piattaforma superiore che io ho messo a 100 mm
Ha senso fare questa modifica e farla circa 60 mm?
Thank you for your suggestion. I'm thinking of removing the original fan motors and apply an I with external power supply at 12 v.
I think is the cheapest system and at the same time valid.
do you agree?
Also I was recommended since it will use the AMC1280USB to reduce the distance between the upper platform attacks that I have put in 100 mm
It makes sense to make this change and make it about 60 mm?

Yes for cooling the motosr , just maybe prepare the connections but put fans on motors only if you notice that is necessary after the first hours tests.

grazie per l' aiuto ragazzi...ne ho bisogno Nel frattempo su un altro forum mi è stato consigliato di ridurre il più possibile la distanza fra le teste a snodo nella base superiore (100 mm nel disegno) perchè questo semplificherebbe molto la messa a punto del simulatore. Oggi mi sono arrivate le teste a snodo e posso ridurre fino a 50 mm centro centro. Non conosco ancora il software perche la AMC non mi è ancora arrivata. Pensate che sia meglio ridurre a 50 mm o lo lasciereste a 100mm? Thanks for the help guys ... I need it in the meantime on another forum I was advised to reduce as much as possible the distance between the rod ends upper base (100 mm in the drawing) because this would simplify a lot the development of Simulator. Today I came the rod ends and can reduce up to 50 mm Center to center. I don't know yet the software because the AMC I is still here. Do you think it is better to reduce to 50 mm or leave it at 100 mm? |

As Doc said, reduce it to 50mm. The closest its positioned the best stability you will have.
Thanks

Hi,
I've got 100mm between rods end on the top plateform.With 50 mm just check that they won't touch them together.
edit : when I look at your drawing and the scale , I don't have the feeling that on the drawing the distance between rods end is 100mm.It seems to be bigger than 100mm?

quindi almeno per l' elettronica avrei pensato a un altra sistemazione:
