Rug Doctor Might Pro

[pauline1948]

I brought a rug doctor from over sea,I brought a converter to go from 240v to 120 it starts up for a while and it turns it self of, I brought a new motor and that does the same so it got to be electric the rug doctor is 1200w my converter is dc so I don't no if it should be ac I tested it on a car battery and the motor worked ok I need help so I can use it,as it cost over £500 it's a shame it just sit in the corner any help I will be grateful for

>>> I brought a converter to go from 240v to 120

What type of converter did you buy? Anything powerful enough to supply 1200W normally costs a great deal of money. e.g. this is the sort of thing which you need: http://www.maplin.co.uk/p/tacima-230v-to-110v-2000w-voltage-converter-n56hf

Although it shouldn't matter in this case, there are sometimes problems with equipment because in the USA the power supply is 60 cycles whereas in Europe it is 50 cycles. Do you know anyone that can help you locally, or even someone who knows someone....?

I assume this Rug Doctor is AC. The mention of 240v and 120 suggests that this is so.
You can't expect a DC voltage converter to convert 240v AC to 120v AC.
I don't see how it is managing to start for a while.
You don't say whether your converter is rated for 1.2 kW anyway.
I don't understand how you tested an AC motor using a DC car battery and a DC converter.

I can only assume I've not understood what you have described.
Can you rephrase what it is you are connecting to what and the power ratings and voltages involved ?

It's not just you, O_G. I got lost too!

The device appears to be a foreign version of this:

but it gets a bit confusing after that!

Thank you all for replying to my question I got a 240v to 110-120v converter
I wet on google, and it came up just say that you put in 300v and the motor wanted 350 it would work for a minute then turn its self of it got something on the motor to tell its the wrong vaulted.
When I read that. it done my head in but that's what mine dose

[Old_Geezer]

But is your converter capable of delivering 1.2 kW ? If not it may drop the voltage to save itself.

[Buenchico]

Is your voltage converter rated at 1200W or more? (Unless you paid a great deal of money for it, as in my link above, I very much doubt that it is).

If you're trying to use a converter with insufficient power capacity then it might well power the motor for a very short time but then it will either:
(a) overheat and burn out, rendering it totally useless ; or
(b) as I suspect is actually happening in your case, overheat and trigger a safety cut-out, turning it off.

Sorry but there is no safe way to use a 120 volt machine on UK 240 volt supply. As you have been told it is NOT just the voltage that is different it is the frequency of the electricity supply. UK and Europe use 50 cycles per second while the USA and Canada use 60 cycles per second. Put simply it means that even if you did buy a powerful enough voltage converter the frequency difference will mean the machine runs at the wrong speed.
Then I have no idea what you are saying when you start talking about 12 volt car batteries, a 12 volt D/C motor will NOT run on 120 or 240 volt A/C power, it is very dangerous to even try to connect a 12 v DC motor to either a 120 v or 240 v supply, it will probably catch fire as well as blowing all the fuses.
How did you buy a 120 volt machine in the first place they are not allowed to be sold in the UK.

My converter goe,s from 240v ac to 110-120ac my motor as got 1200w on it I contacted some one that's selling one in America and said yours is 1200w if I brought it would I need a converter they said its 1200w and it's got a 240v plug on it.that got me thinking when I got it I brought a adapter and pluged it in my socket I cleaned half a carpet
Then it made a funny noise so I turned it of I've tryed converters and transformers the only time it as ever worked is when I just pluged it in to my socket.
