Sounds like you have a good grasp of it all to me Amberwolf....
albeit, I'm still learning too...so I am definitely no expert.
What kind of motor would you nest inside the F&P motor? another smaller outrunner?
The complexities of reverse and the super high torque modes with the ring gear and sun gear spinning in opposite directions makes
me squirm a bit.
I think that you bring up some good points in regards to "idle" modes and current draw. I think that you can avoid huge stall currents at low rpm
by playing some tricks with the controllers. You would need a dead band possibly around low rpms where you would benefit from
reversing one motor and having the other in a forward direction to give you "crawl" gear. Then as you speed up, the other motor
would need to quickly change directions and go to a fast enough forward direction to avoid the dead band zone.
That's why I want to put some one ways in....to isolate the inputs, and to add redundant operation.
In a hybrid app, you could run the ring gear off a honda mini 4 stroke input and run the sun gear off the BLDC.
That gives you full "OR" operation, 1 or the other or both.
Then you have redundant operation via freewheels or oneways for the outputs too...You could have a tri-brid, Human Power, Electric, and Gas.
The one-ways mess with your ability to regen, but oh, well. you can't have it all unless you work at Toyota or Ford R&D
with the hybrid synergy drives. Hell, maybe we can figure it out?
I also think that there is a great potential for a Prius like hybrid drive here. It's pretty cool how the Prius uses two MGs (motor generators)
and an ICE. I think that they Prius has 7 possible modes of operation.. It doesn't have a dedicated starter...it uses one of the MGs to
start the ICE through the planetary....which is cool IMO.
This is from memory, I'll try to visit the prius sites and touch up my memory...
MG2 (Ring Gear drive coupled to differential)
ICE (tied to planet carrier)
MG1 (sun gear)
1. Full Speed Ahead, All three prime movers are contributing to forward motion and torque
2. MG2 only
3. MG2 and ICE providing forward torque
4. MG2 and ICE with MG1 generating
5. MG2 regen and MG1 regen
6. MG2 and MG1 full torque
