Hi

Does anyone know if you can put a 110v plug on a 230v drill so that the drill would become 110v?

Cheers

Yes, you can, but the 230V drill will become a 110V firecracker.

I don't know - why don't you try it and let us know how you get on?

PS. Don't.

Only if you like the smell of melting plastic!

You need one of these:

Or if it is a really big drill:

Would connecting it to a PP9 battery make it a 9V drill?

In what way do you think just changing the plug will change the voltage
of the drill?

I don't think that will help, that converts 240v to 110v - The OP needs the
other way round. The OP has a 240v drill and a 110v supply

The OP needs a step UP transformer like this

(I am not the seller)

It is probably cheaper the buy another drill though.

I wouldn't reccomend this at all.....

..... but years ago a mate of mine had a couple of 110volt drills - he gave
me one and I found a suitable (isolating) transformer for it but it was a
bit under-powered.

He was a mad bugger and did very well running his at 240 volts !

(It was a classic diecast alloy Black and Decker !)

Yes, well spotted! Sorry was reading what I thought he wrote.

(still at least doing it the way descibed has less potential for
pyrotechnics than sticking 240V into a 110V tool)

You may be able to change the armature on the drill for one with 110V
windings.

A 240v drill will run ok on 110v, but at half the speed and a fair bit
lower power. But if its not for a lot of work it may do ok. If OTOH
you've got whole days of drilling to do, I'd get a 240v one, it'll be
quicker.

Just for a minute I wondered if you were going to say ...

Unfortunately, the back-emf in the motor windings is proportional to the
speed, so as it slows down, more current flows, the windings get very hot...
which is how drill motors get burned out. (don't believe me? hold the
trigger in on a stalled drill for a few minutes, smell how hot it gets. Then
buy a new drill).

Hope this helps,

the comparison is not equivalent, and running the motor on lower v will
reduce i, not increase it. Ask news:sci.electronics.design if you wish.

If the novel mains is 110V or 115V it is likely it may be alternating at
60Hz, so this 20% increase will influence behaviour of any optimised @50Hz,
step-up 1:2 transformer and of the (nominally 50Hz) drill motor connected to
the boosted voltage.

We're not tallking about stalling it. Running on a lower voltage and
hence at a lower speed will not damage a motor, all other things being
equal.

Does DC motor theory applies to AC power tools?

"All other things being equal", then yes. But the ratio of excess heat
to power output goes up somewhere between twice and 4 times (linear to
square law, depending on what the limiting factor of the drill design
is). As most hand-held power tools already run quite hot to keep their
size and weight down, you're either at risk of cooking the drill, or you
have to limit it to a far less powerful output..

Yes, except that you obviously have to allow for frequency effects too.
There are no DC motors - if you expect it to rotate, then you have to
make a rotating field somehow, either by powering static windings with
AC or by chopping DC through a commutator. The current in at least some
of those windings always has an AC component.

Univeral / brushed motor designs (every drill) won't care.

The magnetic effciency boost between 50Hz and 60Hz is minuscule
(although real).

Ac fans are routinely speed controlled, and just like drill motors
theyre cooled by their own blades. Fan motors stay close to the same
temp over a wide v range.
