Mostly Permanent Magnet Motor with minimal Input Power

Well not even worth a video on the solenoid setup. I had to use 5 times as much power to achieve the 500 gram pull force.

Your on to something great here Luc-time to make the same type of setup i think-but one more thing to try first. So the idea is to achieve 500 gram's of pull force,using only .432 watts.

Here is the pull force(or torque) from a standard small dc motor.

Hi Luc,
I keep thinking about this aspect of the testing:
For example, if you do the lifting test once per second,it
consists of on/of duty cycle, which means that you apply  power only
half of the time of the cycle, which will be 0.2 W, instead of .4 W per second, to perform the same work.
Which means that for the present setup of 500g pull, you only need to lift
it twice per second by 2 cm to reach OU. If you do it more often - you are in a surplus territory.

This is an interesting test,but what are the ruel's based around the test.?
Would this be allowed-we have a spring sitting under the 500g weight.If Luc can get the weight with spring into resonance,and the 500g weight is lifted that 2cm's twice a minute,dose that still count?-are we aloud to use the spring. If a spring is not an energy source,then i dont see why not. this would then become like a kid on a trampoline.

Thanks TinMan for making this excellent test setup using a standard motor.
Your 1 to 1 pulley is the right way to go to compere a standard motor pull force to my design.
You spring idea also sounds good.

@ telecom, when I came up with this design 5 years ago I ordered many large 2" square by 1" thick N52 magnets to build a super powerful version of it.
I never did build it because most said it wouldn't give OU and then the topic died.
I still have at least 10 or more of these super magnets in the original delivery box in storage . Today they are worth a fortune compared to when I purchased them.
I guess it's time to open the box and build the thing to see the real results!

I was thinking to build one that's at least 8 inches wide by using 4 of these 2" wide by 1 " thick magnets next to each other. That way most of the coils outer magnetic field is used. Only 1" on each sides where I attache the guides would be lost compared to my latest design where only half of the outer field is used.
