United States Patent: 4019103
"An electromagnetic motor and generator is disclosed having a pair of solenoids wound on a cylinder, each of said solenoids comprising three separate but connected windings. A magnetizable piston is positioned for reciprocation in the cylinder and is connected to a rotatably mounted crankshaft. A commutator connected to the crankshaft and interposed in an electric circuit selectively energizes the solenoids to cause rotary motion of the crankshaft. An additional circuit means is also provided for recapturing electrical energy generated in each of the solenoids upon deenergization of the solenoid by said switch. " |
Sykavy,
Yes, the Davis patent has some similarities to this project. The big drawbacks in the Davis design are as follows:
1) The power is ON in the coils too long. You can see in the text that he is only hoping to recapture about 1/3rd of the electrical energy.
2) The stator iron structure is total insufficient to produce high torque.
I have the Davis patent in my files and could have used it as an example in my DVD, but decided NOT to because it did not represent a significant advancement.
In this project, we know exactly how to produce both high torque and recapture 80% or more of the electrical input. Davis may have envisioned performance on this scale, but his design is thoroughly incapable of producing it.
He does show separate coils for recovering the electricity, but does not show how to recycle the recovered energy for immediate re-use, as we have already done in this forum.
This patent is an interesting, historical footnote, but offers nothing in the way of advancing the art at this point.
