How hard can it be to put some kind of electronic limiter on a power tool so if you over-stress it, it doesn't consume enough current to melt the coils?

I assume something like this must be done on electric cars, or instead of stalling the engine, you'd wreck the motor.

here is your chance to do that and become rich.

Of course that will require to you actually do some work
and not just sit around as usual with your dole funds coming in.

trolling:
"He is a well known attention seeking troll and every reply you
make feeds him.
Starts many threads most of which die quick as on the UK groups anyone
with sense Kill filed him ages ago which is why he now cross posts to
the US groups for a new audience.
This thread was unusual in that it derived and continued without him
to a large extent and his silly questioning is an attempt to get
noticed again."

Mains.

You can stall an angle grinder quite easily, just twist it slightly in the concrete you're cutting.

Are you talking portable tools or mains powered ones here?
The current limiting could be done, and as I recall, in battery devices used
to be, as the older batteries did not like huge currents being drawn from
them until they themselves got hot. Not actually noticed what goes on thes4e
days, but I'd have thought like you, it would by now be standard.
mains stuff on the other hand is almost impossible to stall unless you
start rotating yourself!
Either that or the motor is crap to start with!

When working with electronics, my best advice is to do whatever it takes to prevent the smoke from leaking out of the components. Electronic parts require the smoke to stay inside to function correctly!

That's a good way to get the disc to explode and throw bits into your
