The 775 motors are direct current motors used in many projects and that I think are very little known to people.
When we talk about these types of engines, the 775 refers to the motor size that is standard. In this way we can find 775 manufactured by different brands, with different operating voltages and different power, with 1 set of bearings or with two. But what everyone respects is the size of the engine.
Lately I write little but yes Patelo pulls out a new engine, this must be reviewed. I see the news in Fogonazos 1 year of work, 2520 hours to build this wonder.
For those who do not know him, Patelo (José Manuel Hermo Barreriro) is a 75-year-old naval mechanic, retired, which has become famous for the engines it manufactures.
Patelo W-32 Engine
The last 32 cylinders in W, an engine that would be capable of delivering a lot of power if it were not a miniature compressed air. It impresses me, that you get such perfect machines and that they do not have any vibrations. Look at the coins he puts on the motor. As Patelo says, the level of vibrations determines the life of the machinery.
The motor is based on a property of ferromagnetic materials discovered by Pierre Curie, which is that after a certain temperature the materials lose their magnetism and are no longer attracted to magnets.
El Mendocino Engine is a electric motor that magnetically levitates and uses solar energy. The beauty of the engine is watching it run while floating in the air. It really looks like magic.
Formed by two different parts, the magnetic system that makes it levitate and the electromechanical part of the motor that makes it turn. The motor has four faces (square section) around an axis, which form the rotor. The rotor block has two sets of coils and a solar cell attached to each side. The shaft is horizontal and has a magnet at each end.
Little by little and article by article we are increasing our little corner about stirling engines.
This time we found an article with the detailed construction of the Stirling LTD engine in makezine (the link is broken) luckily we keep the content. This engine is LTD, which means that it is designed to work with small temperature differentials.
We have a complete guide on Stirling engines, if you want to delve into this exciting world it is very interesting that you also learn a little about its history, why they work, what their cycles are, the types that there are etc.
Construction of a stirling engine.
It is a machine in which you have to be quite meticulous in its construction. It is not very complicated to reproduce it, but if we are careful we will obtain a much more fluid operation.
Bedini's rally was followed by Jim Watson, a research scientist living in Colorado, Springs. Watson presented two working devices similar to that of John Bedini. Watson's smallest device worked throughout the presentation and the audience could see that the battery was constantly recharging. The largest device, which weighed 800 pounds, was only revealed for 10 minutes due to practical reasons. During this time, a constant 12kw load was removed from the device. The device was powered by two 12v car batteries.
