Simple to make Hilden-Brand style motor

[Nali2001]

Regarding the solid state setup there are in my view a few things that need to be looked at.

The valve setup uses as we know a input coil to more or less 'steer' the field from the magnet. But there are two kinds of 'steering' or switching.
One involves just a little power to the coil to set up a field that 'steers' the magnet field away. While the other method is the 'power way', in this method the input coil (almost) saturates the coil core section and so make it a truly non passable core section (barrier) for the field of the magnet. This method will switch the magnet full power but will require the most input, but will result in 'true switching'. And in my opinion this method is needed for the solid state setup. Now there are a few problems with this. And one of the main problems is that you very often need a lot of voltage in order to drive a core in saturation in a dynamic, say 50hz state. Just try it with a transformer. Just connect it unloaded to a variac and pump up the voltage. Think about a mot core and the thick wire primary which is on there. Well you can connect it to the 230v mains, which tells you that the core even with the thick windings will not even approach saturation at 230v input. You will know that saturation kicks in when the amps suddenly jump up, until that point comes the thing draws almost nothing. If you take a mot core and wrap the main leg with 50 wraps of 2mm wire then you probably still need at least 60v to get it to nearly saturate. So now back to the Valve we are discussing. In order for it to be a hard and true switch we want it to get near saturation so the magnet has no other option then to switch. But you need voltage in order to get there. Don't think that 24v will do much unless you use 10wraps of 3mm wire. This is something I will be testing soon. Since it was a problem for me to get into the 250v dc pulsing range. So in my opinion that is one of the main reasons why solid state valve/transformers fail to see any gain from the magnets. And keep in mind that switching the valve does not cost much only when the magnets has another easy to obtain path of least resistance. In a motor for example when there is a big airgap or the rotor and stator are not yet good aligned, or when you have lenz working against you, you will have to pump in more amps to get the valve to switch.

Then there is this other problem and that is, getting a good dc transformer. Like I said before you can not just pulse a transformer core all the time with the same polarity dc pulses and expect it to give you nice efficient transformer action like you would have if it were ac. The advantage of ac is that the polarity of the core is flipped around 50times per second. That obviously makes for good transformer action since there is a real magnetic polarity change / flip. Now dc is a whole other beast. You give it a dc pulse and then what? Another pulse of the same polarity... Which means that if the core on its own did not 'reset' its magnetic polarity to zero in between the pulses you have no, or very little field change, and without a real field change you have no induction and no output. You are just pumping in amps. This dc transformer issue is a problem on its own which needs to be dealt with if one wants to get a working solid state device. Or you get some core material which can by itself reset its magnetic orientation in between the dc pulses, or you devise means to do it yourself like with a very tiny 'reset pulse' of opposite polarity, to at least try to bring the core magnetic orientation back to zero, in between the pulses.

So you ask why not use ac instead of dc then? Well here is problem number 3 and that is that these valves are always dc setups. You can not really use ac since only one of the polarity of ac is beneficial to the valve switching. The other will just clamp up with the magnet and be useless. If one can come up with such a solid state setup which can switch the magnet with ac let me know. Oh wait there is such a setup:

These were the main points in my view.

The secondary is the coil on the top (C core)  The top is a c core instead of a bar, the dimensions are
not a good fit but I thought it would be "close enough" as a mule. I was pulsing about at about 25 to
80? hertz 50% duty cycle and only at 12 volts. I have built megs and the bulgarian meg but always
there seems to be part of the equation missing....so open to suggestion...

Now that is excellent photography. Good thing you cleaned under your fingernails in the previous shot.

Just wondering if you have tuned your magnet lamination combo. For instance in Fig 26. the best bang for the buck came with 10 mm magnets at .6 amps. It clearer in Table 32 of the patent.

Have you used the same pulsed square wave on a regular transformer? If so, what kind of results?

Thank you so much for your input of knowledge. After playing around with the DC supply and my transformer I'm realizing even more how little I really do know. I'm not sure if I have the time and money to "play around" with trying to learn by trial and error. So simply put. If you are willing, what would be the specifications of a transformer that would have the best chance of working? Size of core, wire, turns, voltage, amperage, magnets, DC,modified AC or something like the belgians'..... I just figure that your best guess is my best guess.

Larry,

Good point... ok I didn't do any of that so will study that a little closer, thanks for the tip

Very well thought out and expressed. And very true, as far as my knowledge has progressed to date.

It might be that the motor is the "only" way to extract the power, as double coils in the same
flux loop seem to have their problems...
