Hi, I have been searching for the videos, can you please post the links. Thank you for any help received.
I've copied the below from my original topic:
http://overunity.com/8429/mostly-permanent-magnet-motor-with-minimal-input-power/msg420188/#msg420188It contains the essential details and developments.
Over five years ago I came up with a unique linear motor design where a coil moves on a steel core between two opposing permanent magnets.
The benefits I found in this design are:
1. The stronger the magnets and the more core surface area, the stronger the push or pull gram force is.
2. The design has no magnet cogging as the cores and magnets don't move.
3. The coils Inductance has next to no change as it moves since it never leaves the core.
4. If designed correctly the coils push or pull gram force is equal throughout the travel stroke.
5. Compared to a standard solenoid my design uses a fraction of the input power, so it can be continuously operated 24/7. A standard solenoid would catch on fire if it tried to continuously push or pull what my design can do.
6. My design offers huge travel distances compared to a standard solenoid.
7. It can be made to travel a 1/4 inch to 4 inches or more if needed while maintaining the same gram force throughout the stroke.
Here is a demo video of how my basic design works:
https://www.youtube.com/watch?v=-eTQ49RcFKMHere is a larger magnet version:
https://www.youtube.com/watch?v=qa1dO8qWPQUHere is a super build version:
https://www.youtube.com/watch?v=f6pc-XNS9uoAll tests were done with the same digital scale which displays pull gram force in 5 gram increments.
Results of the tests in the same order as the videos above:
no.1 has 250 grams pull force with a continuous 1.2 watt input
no.2 has 500 grams pull force with a continuous 0.43 watt input
no.3 has 2500 grams pull force with a continuous 0.43 watt input
As you can see I'm demonstrating that the pull gram force can be increased by the force of the permanent magnet without increasing the input power. Note that test no.1 has 1.2 watt input and test no.2 has 0.43 watt input which is a 65% reduction in input power but still has double the gram pull force.
Test no.3 has 5 times the gram pull force of test no.2 using the same input power since the core and magnet surface area is 8 times wider.
So obviously not just the force of the magnet can play a part but more core and magnet surface area also increases the push or pull gram force.
This is what I've been trying to demonstrate in a nutshell. However, since this is the Overunity Forum people here are mostly interested in OU possibility rather then an innovation.
So to please everyone I did tests to see if the super build could have OU potential even though I knew it would not since the design also suffers of the generator effect as the coil moves in the permanent magnet field. Since it can only move at a certain speed because the coil generates power as it moves, it fights the input power which is coming in the same direction, so we cannot beat the laws of physics here.
Hope this helps
