Default Electric motor burning

Recently bought a 'Silver Crest' electric carrot grater from Lidl. It says
in the instructions not to use continuously for more than two minutes at a
time and then allow time for it to cool off.

However if worked very heavily you can get a whiff of a burning smell from
the motor, even within the two minute time slot.

Is this burning smell indicative of something that is damaging the motor or
can this smell be safely ignored, provided one stays within the two minute
window ?

What is the margin for damaging overload likely to be here, since two
minutes can be quite a short time ?

If it's new, the smell could be from dust / grease from manufacture burning
off normally.
Personally, I can't fathom why anyone would require an electric carrot
grater, unless you breed toothless rabbits?

Those electric carrots are horrible to grate manually.

Suppose it depends if you're grating a couple of carrots, or dozens of
the things.

The faf involved in dismantling, cleaning & storing the gadget makes it
silly for anything less than catering quantities.

I'd have thought something that could only be used in two minute bursts was not very good for catering quantities unless it has a prodigious throughput...

Seems like the answer to a problem that didn't exist :-)

Well I have a bush shredder that smells, but it has a thermal cut out so it
cannot overheat. It trips and a likkle light apparently comes on till ts
cooled down.
I'm not sure what to make of these sort of appliences, but i suppose what
you smell is the windings getting hot and if its a brushed motor, probably
the sparking of the brushes.

Do you really have enough carrots to make such a device useful?

More than four is enough to justify its existence.

You may be smelling ozone (O3) which is generated by sparks from the
carbon brushes.
It usually goes away when the brushes bed in and sparking is reduced.

Thanks to all. Is that what they call * Egotism *, not being able to
conceive of someone needing to grate more carrots than they would eat
themselves.

It comes from those who have never grated a bag of carrots and skinned
their knuckles.

Ozone has a very distinctive odour that I don't think many people would
describe as "burning". There would have to be some serious arcing in the
brushes to produce enough ozone to be easily detectable by a distant nose
over the smell of freshly grated carrot...

I go for overheating in the windings and general hot smell from the
laquers etc. Seems to me that the machine is not big enough for the task
it is being asked to perform. Either that or the OP is overloading it by
forcing carrots into it to fast. Let it do the work, don't force the
motor to slow down much.
