Hi Grum,

If you stop the video at exactly 1:02 you will see the tipping of the brush. About half of the original width.

The purpose or tipping ensures only connection to one commutator segment at a time. Much like your shaved
brush in your video.

Tilting is where Brad means adjusting the brush position.

Regards, Penno

Before we go any further,i need to once again make it clear that i will not,and cannot disclose the full details of the RT--> i think i made this point very clear in the partnered coil thread.

What i am going to do is try(!!try!!)and show that PM's(permanent magnets) can do useful work,and how they do it. From there on,how you apply that knowledge is up to each person here.
I will be doing this in way of the solid state transformer version as Luc has posted diagrams of in the first page of this thread.
I am hoping that Luc will join me on this build,and the testing to go with it,as it is based around one of his test bed's he built some time ago,showing how little electrical power is required to divert the flux path of PM's. Anyone else that would like to go down the S/S path are also welcome to join in on the build. Using the principle the RT is based around,i believe we can make the S/S version work.
This time i(and i hope others)will be posting videos and details on each step of the build,so as in the event that success is had,then it will be all to late for anyone to do anything about it.

@ Jim
The first part of the last video will be up in about 30 minutes.

Good day Brad and everyone,

I continue to update the first page of this topic. Now above your RT videos it says:

The below videos are an archive of TinMan's (most recent first) Rotary Transformer (RT)
Please Note: At this time TinMan cannot fully disclose RT v.3  So please do not ask as your post will be ignored.
If you chose to test or work on the RT version you do so on your own with only the information provided in the videos below. 
At this time TinMan is working on a solid state version (below the videos) which is the main focus of this topic.


@ Brad,
I will definitely be replicating your solid state circuit. It may take me a little more time then usual because of my living conditions at this time.
Like Grum I also like things that rotate so I will also be experimenting on a rotary version at the same time.

Thanks for sharing

Luc

Thanks Penno,

here is few other shots as well

Thanks brad really cleared a few things up. I'll be pursuing both projects as well. Mght have to win a couple of poker nights to pick up the rigol :) grum and I are working on the same motor which doesn't lend itself to that sort of brush adjustment. Can you confirm what Penna has said? At this stage I'm thinking I'll have to look for a different Motor... And explain the deconstructed Dyson to my wife :)

oops our Dyson broke. Happy to say that this universal motor spins up nicely without the stator coils connected. Like Grums it tends to wander all over the place with rpms. I performed the charging a load test with the diodes as shown in Brad's last vid. It was difficult to know whether the charging was affecting the rpms or if it was just the idiosyncrasies of the motor itself.  Just for giggles I put the other stator coil across a reed and stuck a small mag on the spindle. It definitely sped up then.

@Jimboot,

It seems that attaching a magnet to the end of the rotor axle, in the stator attraction polarity, would add the same kind of GAP advantage Art Porter gets. The PM power equation was figured out to equal the amount of suppression strength needed to neutralize the PM field with a coil, by Dr. Dragone. The PM adds that exact amount of electrical power to the motor.

Gotoluc shows in his "Flynn Motor 2" video how voltage regulates the flux of the magnet core. Timan apparently struck the right balance this way to aid the RT's efficiency.

The tipping of the brushes is to adjust the timing,and also to have two rotor segments in contact at once. This eliminates most of the arcing of the brushes,and reduces losses by way of heat. It also allows for the reversing of the magnetic field created by the stator coils to that of the rotors field.

See this video(if you havnt yet) of my early experiments,and you can see how much more efficient the standard RT is than an !off the shelf! motor that was designed to drive the fan used in the test.
The standard motor on the house fan is suppose to be 86% efficient minimum,but for arguments sake,lets say it is only 80% efficient. The RT is 40%+ more efficient at running the fan blade than the motor that was designed to do the job. Only 1 stator coil is being used on the RT at the time this video was made,as it was early days-as you will be able to tell with some of the descriptions i give lol.

How is this magnetic amplification?
In fact,how is this anything at all. I see a pulse motor with biased coil's-i see nothing else.

As opposed to 4 rotor segments?

A switched polarity could deliver twice the repulsion followed by a neutralization pulse. The same pole switch circuit could power a coil charged rotor with 2500gm to 1/2 watt ratio, with very powerful magnet stators.

Well that was impressive. I hadn't seen that before. Thanks. What is the better motor to work with? The washing machine or fan.? Which was the easiest to tune for optimum performance?

The later vids it was across 1.5 ? I think I'll have to go back and check. It was the vid uploaded last night.

kEhYo neutralizes then shuts the coil off and allows the backing magnets to repel the rotor. He could power the coil from both directions with a DPDT current reversing reed switch. The same motor would then deliver twice the Torque. In attraction, the backing magnets would have twice the force with coil on in the same direction, then reversed to neutralize at TDC. kEhYo's circuit only delivers 1/2 the motor's potential power.

the fan motor is just a standard induction AC motor-no mods can be made. It was used as a benchmark for efficiency-so as i knew i was going in the right direction with the RT.

Sorry i didnt make that very clear-my mistake.
2 rotor segments at each brush-50% of the time there is 3 segments per brush in contact with each brush-so 4 segments at 100% and 6@ 50% time on all up.
