Hilden-Brand Magnet Motor

Hi Rob,

I tried to imagine what you have suggested and I failed, sorry for this.

Could you (or someone else) make a simple hand drawing (even in Windows Paint) of how you mean the semi circle cutout of the rectangular slab?

It is ok that "the smaller the cross section, the higher the flux" but the limit for this is saturation, isn't it?

Thanks

Has nobody figured how this idea can be turned into a motor yet?

There are pictures of some motors Jack has constructed earlier in this thread - about page 12 or so.

Something like this:


Uses the following:
Total current = 0.008 Amps
Voltage Drop = 0.0557591 Volts
Flux Linkage = 0.0147367 Webers
Flux/Current = 1.84209 Henries
Voltage/Current = 6.96989 Ohms
Power = 0.000446073 Watts

Max flux is 1.2 Tesla

Hi Rob,

Thanks for the simulation and the picture, now I understand how you meant.

And now I also agree with your notice in your first message:

"The ideal way would be to get the flux to go through the whole rotor to another valve to complete a circuit."

Because that would seem to be the most efficient way of making use of all the flux coming from the permanent and the electromagnet.

I did some more tests and I think I will scrap that as an idea, although there is loads of dense flux through the narrowed section, it is of not of any mechanical use outside of the core. You cannot get it to attract anything.
Looks good but is serves no useful purpose.

What is needed is something that looks like a south or north pole that is able to attract or repel a magnetic rotor or attract a steel rotor.

I am looking at another method at the moment, using 2 valves, 2 bars and an extra neo magnet between the 2 new bars, I will post an image later on.
The two valves will control the flux direction of the new neo magnet, in the two large bars.
Then using 3 x less powerful cermic 5 magnets for the rotor.
So 2 field poles and 3 arms on the rotor.
Its all theory, I need to get some laminates to try it out.

Rob
