Flynn PP Motor Idea

You will ever stay (C8-ceramic magnets related) in the
400% range !
But you can also change the output-power through
3x/4x...wheels use !

  You mean use bigger wheels? or more wheels?

A physically "provocating"question:
probably you will get with bigger wheels an extra-lever effect,
but my statement has been related to "more wheels use" !

  Ah, ok. What if I had two devices running independently. At (in theory) 400% each, would that be a total of 800%? If so then what is the difference of making two devices vs putting more Flynn devices on the same device. My head is spinning, lol

pure maths:

wheel-concept 1 input  1 unit,100%   = output 400%,4 units
wheel-concept 2 input  1 unit,100%   = output 400%,4 units

resume:2 units in-,8 units output

The use of more wheels will only get a higher power-density,
but the relation 100% in:400 % out will stay !

  Thought of using a reed switch, but wouldn't you need a magnet that is exactly the right sizie in order kick it on and off at the right time? I was thinking more along the lines of a light senser. Use another wheel with notches cut out in the right spots to allow the light to pass throught at the right time, kinda like the old mouse wheels used to work. Is a hall sensor the same as a reed switch? Anyhow a hall sensor or a light sensor would be better to reduce drag of a physical one.

Nice motor design drak!, I wouldn't use a reed switch, as the timing of reed switching is... problematic, at best. Reed switches are better for detecting the absense of a magnetic field than the presense of one, there are normally open, or normally closed ones. The normally open ones are the ones they use for alarm systems, to detect when a door or window has been opened. Those types of applications are what they are best at.

Hall effect sensors are powered sensors, however they are far more reliable at proximity switching than reed switches are. I don't know much about mosfets myself, and would probably just use a relay for polarity switching.

The MOST critical part of the construction of this device, will be permanent magnet positioning, and switching. All of your output power hinges on those two factors. Other factors would include permanent magnet size.

If you design your rotor with specific large magnets in mind, you can cut holes for them in the rotor so that one pole faces inside and the other faces outside, you can use the inside pole for motive force and the outside pole for inductance in coils, turning it into a motor/generator.

For pure motor function you could just remove the coil assembly and allow the shaft to do work.
