Ernest,
The crank of a motorbike runs from left to right (Twin), the LHS is an external case, in the inside of that case is mounted the rotor (generator internal windings) and their fixed in place. I believe that is opposite to your design.
The timing wheel pick-up is just outside the fixed rotor. The external housing of the generator is attached to and spins with the crank. The generator housing has the pick up wheel attached OR is the pick up wheel - it may be duel purpose - I like that idea as it reduces component numbers.
When the external casing is attached it slides together nicely. I notice the outside casing is doweled, for obvious reasons. A nice design as it makes the spinning parts more easy to balance.
I was thinking I could fix the rotor ( with pick up) to the back of the PSRU and attach the generator shell to the flywheel damper assembly.
If your design is easier I am happy to look at that as well - I'm just researching as much as I can while I have some time to do so. I have some big projects coming up soon. One thing that concerned me about the permanent magnets was the heat sensitivity. What Amperage is your generator?

I was considering a Suzuki Motorcycle generator for my Aircraft application is has the internal windings held on the outer motor casing, with the outer shell connected to the rotating mass. The outer motor casing which holds the inner core also has the CKP pick-up while the rotating shell has the timing wheel. Very neat and simple.
However is a CKP pick-up?

George, I'm not completely sure that I'm understanding you.
It has a wound rotor (the rotating part) that is on the outside?
The stator (the stationary part) is attached to the engine?
What is a CKP?
I wanted to go the permanent magnet route in order to avoid slip-rings and brushes and such. It's modestly heavier, though not by a large margin; however, it is a much simpler setup...electrically and mechanically. Even the regulator is a stone simple affair.
I'll experiment with getting a VR sensor signal from the flywheel once I get my engine running. I don't need to pick a signal up from there, but I think it will be really easy.
