Regenerative Braking System

OK magnetic resistance granularity theory has been completed.


And I think this explains why the more slots the better.  But it doesnt explian why they are wound AaA and AAA and stuff.  This is a different reason which I believe happens because of overlapping.  We can pull this apart next.  Its Important to know what and when and then we can understand why and how..

We divide the pole count by the slot count, then to achieve a constant we divide it by the pole count again to get Magnetic granularity resistance over one pole.

Then multiply the Magnetic Granularity Resistance (MGR) by the telsa of the magnet.  The result.

To get the total resistance over all poles we multiply the result by the pole count.  

Say a Gm magnet has 12 tesla (12t) over the one pole.

Magic Pie

56/63=.0888/56= 0.0158

12x.0158= 0.1896


The total magnetic resistance of the pie would = 0.1896 tesla x 56 poles.

Magic pie with 56x12t magnets has 10.666 tesla resistance over the whole hub

Well under 1 magnets force trying to slow a 26' wheel.


The GMHBS

46/51=0.901.

0.901/46 poles = 0.0196

12x 0.0196 = 10.823 x 46 poles = 10.8192

Gm HBS hub with 46x12t magnets = 10.823 tesla resistance over the whole hub


Magic Pie = 10.666 TMR (total magnetic resistance).

GM HBS= 10.823 tesla TMR

The Magic Pie wins.



The 10.66~10.82 tesla resistance is spaced over the entire circumference of the poles.

Then you need to consider the layered weight diiferentials of the different materials used to make a hub wheel the diameter of the outside wheel.  EG tire on the outside spokes on the inside and magnet ring further inside ETC, and the energy stored at a given RMP, use PI and the accrued newton meters force upon that 10.66~10.82 tesla and you will get what that 10.66~10.82 tesla means to the freewheeling of the Magic Pie.

I don't want to go this far but you get the point.

I am on the right track but I am missing an equasion when I consider the total MFD magnetic flux density of the magnet rim.

Needs fixing.
