While I was confirming that Grainger has capacitor-start split-phase

While "more efficiency" is a good thing, I find myself wondering how
much the average efficiency of small motors will actually be increased
by this, and what the side effects will be. Generally speaking
"increased efficiency" translates to "costs more up front" so I suspect
we can expect the prices of tools using "general purpose motors" to go
up.

Can the Chinese meet the new standards? If not then this might be a
defacto ban on Chinese motors, which would be good for American motor
manufacturers but also mean price increases on all sorts of things.

The Chinese are in outer space, why would they not be able to make such
a simple change to meet this standard?
I highly suspect that because the companies, like most any brand of tool
that is built there and sold here, dictate the specifications of the
product and that a simple change in the motor will not be any kind of
issue at all.


Then there's a little detail--"Run capacitor provides winding with
increased energy to help improve efficiency". I don't know if that's
specific to Dayton or if it's across the board--if so, if all new
general purpose motors are required to be capacitor-run, then we can
expect to have to replace those capacitors with some regularity.
