Subjecf Re: Bipolar vs MOSFET Switching Clarifying the Stepping Ladder

Dear friend Ufopolitics,

Great question and thanks for raising it, because this is exactly where terminology can get crossed.

It is not too early to tell anymore, based on the mechanical commutator drawings you shared.

The short answer is:
Yes, MOSFETs are still the correct switching devices.

What changes is how they are organized and controlled.
When I previously mentioned a "stepping ladder," I was not implying that MOSFETs were no longer suitable. 
The "ladder" refers to the State-Machine Logic and Sequencing that replaces the mechanical commutator and not to a resistor ladder or non-MOSFET switching topology.
From the Bipolar Mechanical Commutator behavior we now understand:

• The system does reverse polarity every half-cycle
• This means the solid-state equivalent must behave like a Bipolar Switch
• Electrically, that translates to an H-bridge topology
• Practically, that still uses MOSFETs, arranged as complementary pairs with enforced deadtime

So:

• The system is bipolar in function
• But MOSFETs are the correct and preferred devices to implement it
• The "stepping ladder" is the 32-State Sequencing Logic that steps through the commutation states, emulating the mechanical overlap and break-before-make behavior.

Nothing here excludes MOSFETs in fact, the architecture we are converging on is exactly what modern Motor-Control and commutator-replacement designs use.
So the answer is:

• Bipolar behavior: Yes, required
• MOSFET switching: Yes, absolutely
• Stepping ladder: logical/state sequencing, not a different power device

Thanks again for your dedication to the project the mechanical clarity you provided is what allowed this to lock into place.

Hello Team.

Since 32 segments are so promising, is there any idea that we can run the commutator even slower speeds using 64 segments? (900 to 1000 rpm).
I understand that building such a device will be more complex and assuming it must be bigger to maintain the segments size also the brush size accordingly. (not to compromise make before break)
 If Mr.Ufo gives me a green light, I will start building it since I got a metal lathe to have everything built in my shop/garage.

Hello Team.

Hello Art,

Since 32 segments are so promising, is there any idea that we can run the commutator even slower speeds using 64 segments? (900 to 1000 rpm).
I understand that building such a device will be more complex and assuming it must be bigger to maintain the segments size also the brush size accordingly. (not to compromise make before break)

Yes, your math is correct, as for 50 Hz we will need just 750 RPM's and for 60Hz would be 900 RPM's then a Max of 1000.
However, as you wrote, it will require a bigger setup, a larger Diameter on the Copper Cylinder, then your Radius will increase as well.
A larger Radius (as the Arms/Levers) will require more force (torque) to turn them, as also a larger radius will increase Centrifugal Forces (CF).

Then you will need to find a Motor that have enough Torque to turn Four (4) Brushes at the required speed, adding higher CF.

On a project like this, it requires that you acquire all the components you will be using on your setup, mainly the Motor, so you will need to find a motor that can turn those Four larger Levers and still not be using a large amount of Currents and Voltage.

The goal here is that our Driving Motor will not spend too much power (V&A) to operate the commutator. Considering that all that extra power required could be used on our Input Circuits.
As also, that we are looking to "easily" supply/feed that small motor with the LEAST Power, so we can reach a "Self-Runner".

The other critical point you would be dealing with would be the Segments Angle (no matter how big in diameter you go) it will be 5.625º, so your brushes can not 'touch' Three (3) Segments at a time.
The Max Number of segments your Brush could contact are Two (2)...and honestly, I like brushes to be even less than 2 segments at a time, and still keeping the MBB required here.
Like One and a half segment to just one segment brush size for lower speeds will be perfect.

The other challenge here with 64 segments, is that you will have Eight Quadrants (instead of Four(4) on 32) that means you will be reducing it to Four Full Cycles in 360º.
This may look ´great´, however, the accuracy required here would be the same as a "Swiss Watch", meaning very high.

If Mr.Ufo gives me a green light, I will start building it since I got a metal lathe to have everything built in my shop/garage.

Art, It is not about that I give you a 'green light' here, it is about that you conceive/calculate the whole thing, before getting involved in just 'one part' of this setup (as is the commutator building and cutting into smaller segments), without looking at the consequences/challenges to other components on the build, just to get a lower operating speed.

The "Golden Ratio" on this setup is NOT 32 Segments...

Understanding Golden Ratio as the 'perfect ratio' which will satisfy all other functions without taking some others to a 'critical' or 'stressful' state.

The Golden Ratio for this build would be 36 Segments.

• The division of 360º (a Full Revolution) of 36 segments will be exactly 10º.
• So, instead of 2 Full Cycles within 360º for a 32 segments, we will have Three (3) Full Cycles for a full revolution of 360º.
• At 36 Segments we will have Six (6) Quadrants of 60º each.
• So, instead of reducing speed to Half (1/2) with 32 segments, with 36 segments we will be reducing the speed to One Third (1/3).
• Then to reach 60 Hz we will just need 1200 RPM's  [instead of 1800 RPM's with 32 segments]
• For 50 Hz just 1000 RPM's (3000/3) [instead of 1500 RPM's for 32]
• As the Max would be 1333 RPM's [instead of 2000 for 32 seg]
• All these advantages and we will be just adding Four more segments to the 32 segments setup...

This is why I consider it is a "Golden Ratio".

As going any higher, you will be altering all other components and setting them on critical and challenging state.

This was just my opinion about this build, as I have dedicated so much time studying all these Geometries and best possibilities for an Excellent/Top build.

And YES, I am -now- considering to move (again) to a 36 Segments Commutator, instead of a 32 segments...after making ALL this Analysis above ...THANKS to you @Art Z. !!!

Hello again,

About my previous post related to "Golden Ratio"...I am correct about all the numbers related to a 36 segment commutator...

Except, that it can NOT be applied to my actual Setup, which is based on EIGHT [8] Contacts at the Sequencing Coils.

So, in order to "make it fit" into SIX 'Sexants', I would have to REDUCE Contacts to ONLY SIX (6) terminals at the Sequencing Coils...which means I would have to reduce Total Coils to 12. (taking off 3 coils)

• 12 Coils -as built now- would NOT cover the length of Main Secondary.
• Plus, it will reduce the Operating Resistance per Group then the Currents (now would be six coils groups, instead of eight)
• In order to cover the length of main secondary, and satisfy resistance per Group, ALL Sequential Coils must be rewound, with wider measurements and more resistance.
• Neg / Pos. Brushes on Commutator will NO longer be Sync at 180º apart...but at 120º...not good for balancing on rotation.

And I am NOT going to do that huge conversion at this stage of the build.

So, back to 32 Segments.

Sorry about some confusion this could've created...but I said: 

I will "CONSIDER" moving into 36

....as the result is a big NOPE. it won´t work.

Subject: 36-Segment Follow-Up – Staying with 32-asegment

@ Ufopolitics,

Quick clarification on the earlier 36-Segment idea.
While the math for a 36-Segment Commutator is correct, it does not fit Your actual setup, which is based on eight 8 Sequencing Contacts.

Moving to 36 segments would force indeed a redesign.

Given the current architecture, the 32-Segment Commutator is the wise and correct decision, as it preserves electrical balance, mechanical symmetry, and avoids unnecessary redesign.
