Here is Mr. Fouquet's answer for the Santos,
Hello Mr. Ranelucci, I have just spent delicious minutes to the reading of this forum. Which are positive or negative in connection with our product, all the remarks are interesting. There are really experts in “paste”, and I acknowledge that exceeds my competences, even if one finds fundamental French laboratories which tested our product: incorporation of air, to turn etc slowly… I learned how not to take part directly in these forums, I know that it is generally appreciated very little because much from manufacturers benefit from it, with final, to make promotion… (even if I am accustomed to the English, I travelled much to the USA formerly…). All is not “scientifically precise”, in particular the variator of tension (at the end): the fact of lowering the tension on an engine of this type (asynchronous) will not decrease its speed… (just to decrease the couple (Torque))I will try to launch some prototypes of a “screw gearing without end” with a higher report of reduction. It will take me several months unfortunately. And then, initially it will be right a technical test of validation, and a validation of cost and feasibility “for me”, and can be of exclusiveness for you if it goes. Currently in 50Hz: engine 1500 rpm, 1470 rpm with the slip, 70 rpm at exit, is a report of reduction of 1/21Actuellement in 60Hz: engine 1760 rpm with slip, with 84 rpm at exit, one finds well the same report of reduction of 1/21Si one aims at a velocity emission slightly lowered compared to the 50Hz, of 65 rpm, it is necessary that I obtain a report of reduction of 1/27. Il' work on it, and I keep you informed. Contact our dealer in Montreal, they are very nice people, I was there in November last year and I have an excellent memory of it. Sincere Salutations !
