All Permanent Magnet Motor

[magnetman12003]

Here is the open source description of the motor.
First you must buy a couple of 190 mm ceramic ring magnets, make a round wood centerpiece for both of them and put a 12 inch  8 mm non magnetic rod through the center of each wood piece.
The bottom magnet should not be able to move.  The top magnet must easily spin with its ""SAME""
Polarity facing the bottom magnet.


Now you must buy or fashion 45 degree wood or aluminum blocks and bond them onto the top large ceramic magnet.  In a circular form.   Up to now you will be able to spin the motor easily with your fingers.
Now for the interesting part. Powerful neo block magnets must be bonded onto the top side of each 45 degree angle.
By extending the """LENGHT """ of the 45 degree angles considerably we now will be able to get
The setup to rotate.  How to do this is by bonding 6 inch polycarbonate tubes to the underside or topside of
Each of the four 45 degree angles.  Inside the tubes are placed neo rod magnets that oppose the polarity of the block magnets.   Now the GRAVITY weight of these extensions will cause the setup to rotate hands free.
I hope all this information is useful in your individual builds.
ALL ABOVE INFORMATION IS OPEN SOURCE.

Hi Tom,
Thanks for the description, it sounds interesting.  Perhaps a short video with good camera focusing
on the setup when you let the rotor start rotating from a stand still would be also helpful. 
I know your previous video was deliberately out of focus.

Here is a photo of what it looks like without the polycarbonate and rod magnet extensions on the underside of the top 45 degree angles.

magentman12003,


Will downward pressure from the 4 - 45 degree- block magnets impart spin motion in the opposed polarity magnet ring below?

Actually the missing part in the picture would be the most interesting one to see What is that grey disc underneath the top plate? Did the initial video contain the rods? Also you're saying about two ring magnets (190mm) but both in the video and in the picture the second one is missing.
Thanks by the way for sharing all this! And as far as I can see it's a different design than I thought it is.
