Blueprints for Howard Johnson's Permanent Magnetic Motor(not adequate to build working unit)
Preface CommentFrom: <Douglas@mchsi.com>
Comment about Page 3 of 4From: <Douglas@mchsi.com> Sterling, Here is page 3 of 4. I did make two changes in the blueprints from what I had first received. Knowing that prototypes would be worked from this basic plans, I put in the non-magnetic stainless steel 304 and took out Aluminum. In my experience Aluminum will cause problems that will make it almost imposable to balance the fields. Next the magnetic shield. It said to use a sheet of Co- netic [?] AA Alloy rolled into a torus [?]. But I had problems passing the butt where two peaces of shielding came together. So I say use a perfect Torus [?] with no seam or butt joint. You could state that these plans are improved design by Mann in these areas. I also have some processes that will even out the differences in the magnets. If someone orders some magnets from a commercial provider, the magnets will not be close in power, in field shape or exact pole locations. Mass production magnets will not work!!!! Douglas
Other Pertinent CommentsScaling up or down
Sterling,
One thing that I did not say about the
blueprints, I do not think at they can be SCALED up or down in size, or
that the magnets power level can go down more than 10% or up no more than
20% over the Sm Cb 18,and all magnets must be as perfectly alike as
possible . The stator and the rotor magnets must have the same type
power level magnets. The physical size of each part magnet, and shield are
in a balancing act with the fields. In each step of making a
motor is important to keep your mind on the magnetic
field not on the just the parts. To Scale the motor up or down in
size we must keep in mind of what these changes will do to the
fields, and how the shield will work under the new size.
