Mostly Permanent Magnet Motor with minimal Input Power

[wattsup]

I wonder if I recognise your coil.

Is it the low current coil on the 8:1 mains power transformer of a microwave oven?
If so, they are available to us all for peanuts - a visit to a recycling centre, and
an amusing evening in front of the TV cutting through the transformer with an angle
grinder (hack saw will do), and soaking the result overnight in water to soften up
the paper/card packing around the coils in order to get them off.

Wow, that sounds like a good idea to get them coils off. I have two microwave transformers with the tops off and I never found a way to get the coils off. Hmmm. I will soak one of them tonight and try it tommorrow morning. I should be at home all day since they are announcing a good snow storm tomorrow and on those days I stay at home and work on OU. Just love them snow storms.

There is a former member named @JackH who passed away several months ago and he was doing some great work with magnets and coils.

@powercat
thanks for your PM on this thread, in the meantime I also noticed it at the energetic forum where I answered in the meantime too.

@Luc

regarding the vertical arrangement wattsup mentioned, I recall an old patent where a permanent magnet was placed under the core of an electromagnet and this extra flux helped more than double the lifting height against gravity  with the same input current to the electromagnet, see this link and the patent drawing: http://www.overunity.com/index.php/topic,1621.msg16347.html#msg16347

Hi Gyula,

yes this works! but how do you get the magnet (weight) back up once it has used gravity?

Hi Paul,

you know me I always try to salvage and reuse stuff but this one I winded the coil from new magnet wire since it needed to have such an exact center opening and also to be epoxied between layers during the winding so it can all hold up if I decided to drive it hard.

Hi Luc,

Well, sorry I did not mean using it in your present horizontal setup but in wattsup wheel setup he has showed where he wishes to offset the wheel balance by pushing objects linearly up whenever the vertical course for them just passed the 12 o'clock clockwise. I thought here to help the upward linear move with that 'under'magnet, then, as the wheel rotates clockwise, these objects will return by sliding back again due to gravity. I only meant here using this trick, you get more upwards movement for the same input to the electromagnet coil.

Okay I see,

it would work but one thing to consider in wattsup's design is maybe the quick launch (at desired time) may cause a braking of the wheel at that timing point???
