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 ? |

Personally, I can't fathom why anyone would require an electric carrot grater, unless you breed toothless rabbits? |

snip 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... |

I wonder if they also work on Sprouts?

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? Brian -- From the Bed of Brian Gaff. The email is valid as Blind user. "john stone" wrote in message ...

It usually goes away when the brushes bed in and sparking is reduced. |

You may be smelling ozone (O3) which is generated by sparks from the carbon brushes. 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. -- Cheers Dave. |
