If all the curvature changes are necessary on the rim, you can a loft across multiple planes, tightly packed to get the detail in that rim. Otherwise, a mixture of fillets should do just fine. In fact, your models seem like pretty good approximations.

What exactly are you looking to closer approximate?

I'm guessing the front of the motor is the one you're showing multiple images of?

If you used a sketch to extrude the body of the motor, then you may be able to use an offset of the outline to create the front. Add a fillet, then cut the reliefs for the machine screws.

Attaching your file to the thread will get you more detailed answers (File|Export|Archive files (*.f3d)).

Something like this?

That's done by Lofting three profiles, with the first being the main perimeter, while the second and third are on offset planes and have that perimeter offset inside. And finally Filleting as required.
