Hi All,
Thought I would write this as it came to me during a call of the wild. How to get more out of the SG in rotational speed and a higher COP. It is quite simple really. You can talk about all these special lubricants all day long and still not understand. Lubes help but do not address the mechanical issue of rigidity.
When the magnet passes the coil core center the magnetic field of repelling tales place between the north magnet and the north coil there is a very abrupt kick talking place. We need to make sure that we take full advantage of this kick and send it to the wheel 100 percent.
The question is are you getting all of this kick to the wheel? There are several factors that could deter this from happening.
1. Magnet mounting to the wheel......epoxy vs tape
2. Coil Mounting.......is your coil bottom mounted?
3. Frame construction....does the frame flex when this kick takes place.
Most of you have epoxied or glued the magets to the wheel. This is one of the best attachments known for rigidity. I would be willing to bet that most of you like me have mounted the plastic coil by screwing the bottom of it to the base. If this is how you have it mounted then I can guarantee that you are loosing a lot of the kick. The plastic spool flexes during the kick action.....resulting in lost inertial going into the wheel. Also if you have a riser that the coil sits upon...is it rigid also?
This is probably one of the most widely overlooked issues with any construction. As I come from a tool and die background this is one of the things we look at all the time dring the engineering and construction phase. I cannot stress rigidity enough!
Let's also consider frame construction. If the frame even wiggles it is lost wheel energy. When one considers how high the wheel supporting limbs are how narrow the mounting face is is does not take much force to wiggle the wheel assembly.
I have briefly discussed several aspects of rigidity in this article. If you are not addressing all of them then I can guarantee you are not getting the most out of the SG.
Consider each of these items and apply the rigidity aspect to the entire assembly first before you get carried away with special lubes.
One last thing......consider the construction of any electric motor. Ask yourself how rigid the design is. This how you should consider the construction of your SG. Everything rigid!
