With almost every brand having an Electric Car on the market or coming
soon, it leads me to think, are there some generic designs of motor, and
controllers that these firms are all using (like Lotus used to design
Suspension for many brands).
Setting up an efficient motor production line from scratch would need some
advanced thinking - surely they are all buying into existing manufacturing
engineering.

Any thoughts as to who the big players are?

Don't think Lotus designed suspension systems or indeed complete engines.
They tended to fine tune existing designs as consultants to the makers.

Wouldn't the same apply to cordless drills? Just about as many makers of
those as car makers.

IMHO, it's more likely to apply to the battery makers.

GKN Power systems supply drive shafts and EV motor
systems to many car manufacturers.

Those are called "crate motors".

There are some for BEVs.

The big players don't use them.

GM put out an article a few months back,
where they showed pictures of their
"engineering fleet" of electric motors. And these
will be what eventually appears in their
vehicles. The things looked as ugly as a pile
of used GM transmissions.

VW has a few "common platforms" for its vehicles,
and the Volkwagon Microbus thing will use the same platform
as one of the existing cars. Just change the body on
top, retune suspension and so on. I hope they
don't forget to put a gasoline heater in the glove box.
Think how that will extend the battery range.

Very interesting - thanks.

Actually the electric motors are VERY simple. I've made little ones for
model planes, so am sure a manufacture could, The winding of the coils
requires the sort of kit that winds any other leccy motor or alternator,
so probably manufacture is subbed out to firms with it

Its the design, especially of the electronics, where the magic lies.

If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
time as the State can shield the people from the political, economic
and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

I think car motors are in another league. Some use welded copper bars as
the field winding. Neobdinium magnets in armatures.

Not really a huge difference - that's a fairly standard way to achieve
very high currents. and my motors had neodymium magnets in the rotors too.
