Magnet motor "Carousel"

[ramset]

Boris  My post above timed out so I could not respond there [with thank you for answering about Triangles liquid nitrogen comment in Yaldiz motor [ https://overunity.com/8870/muammer-yildiz-magnet-motor/msg548244/#new   post 790 ]
IMO understanding how that could work [even if a trick] still interesting engineering discussion towards a much better understanding.

Thanks again and for sharing your work.[ there are many curious hoping to learn here]

Hi !    Today we have an example of the use of exotic materials in magnetic motors .

               We have a magnetic piston moving in a cylinder of non-magnetic material  ( watch the picture ) ,
       on the opposite side of the cylinder there is a ferromagnetic material with a low Curie point .
     The ferromagnetic properties of such a material disappear at a temperature slightly above room temperature.
   When a magnetic cylinder is attracted to a ferromagnet, it compresses the air in the cylinder.
    The air heats up from compression and causes the ferromagnetic to lose its properties .
     When the piston moves in the opposite direction,
       it does not experience attraction since the ferromagnetic properties are lost for some time.
       At the same time, the air expands, returning the energy spent on compression .
              Thus, we receive additional energy.
           the time after which a change in the properties of this material occurs can have a wide range.
         Thus, you can change the speed of rotation of this motor.

Hi ! 

                Here is the  E - Carousel  ( Version B ) . Electromagnets are used. The design of the engine admits an analogy with automobile generators where rotor magnetization with low losses is applied .
                    The E - Carousel can have many different coil and magnet arrangements .

                    how effective can tests show .

Regards

Hi Chet K !  I have not dealt with freezing magnets . I know a little .
     There are several phenomena under this name.
  1 magnets change strength with temperature
  2 at a certain temperature, a magnet can give a narrowly directed beam of a magnetic field
    (  it drives magnetic motors with tilted magnets  )
  3  frozen superconducting magnets have a magnetic field that is separate from the magnet
  4 there is instant cooling technology with magnetic field and inductive action
      ( using the Curie point controls the magnetic shield )
  5 there is scientific work on frozen magnetic fluxes ( sometimes found by Google ) I haven't studied it .

               These technologies are not for garage .


Best regards ,

This attached file is one approach of lowering the temperature of the magnets in a motor assembly.  When the parts need to be cooled are rotating, then this may be helpful for you.  The materials need to be thermal conductive at the same time non-magnetic.  There are other ways, but it is good to look at all of your options.

Hello . Here is the magnetic motor Carousel .
  the principle of operation of a magnetic motor is shielding the magnetic field
in such a way as to create an inequality of forces on different sides of the rotors .
The motor consists of two rotors mounted at an angle . 
For synchronous movement of rotors, magnetic retention of opposite poles of magnets is used .
When the magnetic shield moves from position AB to position A1B1, motor rotation occurs .
Rotation occurs because the receding magnets are covered by a magnetic shield,
and the approaching magnets are attracted without hindrance.

                The design is subject to change. magnets can have the same poles to each other .
the magnetic shield can have many options to achieve efficiency and prevent induction heating .

                                                                                                         To be continued


Regards ,
Boris

I have tried to find magnetic shielding material to use with motor designs.
I built the attached the following test fixture to do that.
It may save you some time to test the materials in a fixture before building a prototype.

I wish you the best!
