Back in the 1930s, I believe it was Dodge that manufactured a car where the starter was also the generator. It must not have had a bendix to mesh with the flywheel because it was said to be very quiet when it started

Directed to the electronic wiz types.

This is not a development issue but an educational issue as
I would like to understand the issues associated with
developing a starter alternator.

Personally I believe a combined starter, alternator,
flywheel, damper, timing wheel and pick up would be a great
advantage (we live to dream).
Some systems use the combined starter alternator attached
to the gear box shaft just, between the motor and the
gearbox fluid damper.

I believe from talking to Bill Jepson that getting
sufficient power from the current winding used is
problematic but that there had been major improvements in
this field. Also reading a little on the Internet ( if I
understand it correctly) an alternator is AC ( alternating
current) and a generator is DC. As Batteries are DC and
starters are DC, we would need to use a DC generator
winding in the starter generator (someone tell if I'm
wrong here).

Of course nothing is as simple as this, so I'm keen to
understand the issues associated - from anyone out there in
the electronics world!?
