Hello!
So thanks to the generousity of active and known SOHC4 user
calj737, I have finally begun work on my CB550 (and more) Perm Magnet Alternator (PMA) Project!
The idea sprung up from seeing my previous short lived project, XS650, having similar charging issues i see expressed for the SOHC4s. Then a well known XS guy made a PMA solution for the XS, giving it the ability to go to a kick only, batterless life. The PMA also has no wearing parts, further making me like the appeal of a more reliable, simple machine.
When I decided to just make the commitment to finding my dream project, CB550, I saw no solution existed, or at least that i could find.
So, like i do with a lot of stuff, I decided to give it a go.
I might succeed, i will likely fail. But I will try, and learn in the process.
Just need to learn electromagnetism (I was previously a crap physics major, so not a far leap, still not easy), generator/alternator design, and source all the materials/services needed without losing money should I succeed the prototype stage.
EASY PEASY
Cal sent me a CB550 rotor, field coil, cover, and stator.
First steps are to replicate the parts in Solidworks for design reference (and to share with you fine folk should you need 3D models of them), and to send them back to Cal.
First up is the rotor. I could model the claw poles, but they are not exactly needed, unless i wish to run a sim of the current design. Not looking to make more work. This will do for any design purposes.
To measure that damn "taper into flat, into thread" bit, I took measurements in many horrific ways that tolerance stacking will murder me. But I figured out some ways to remove error. I also remembered I had some replication puddy I was "gifted" from work. I will check my initial measurements with that replication later.
Next up, stator measurements-to-model...
