Motor Question

Ask your local certified Electrician about the possibility of "single-phase" operation...assuming you (he) has access to actual NEUTAL line.

220V is single phase supply.

What is the amperage draw of the motor...?

Don't you also want to know the color?

Home use.

You don't say where you are. I can't imagine a US home with only 220vac, so I assume it is not in the US.

You are going to have to get your voltage to 120 with a transformer. If your power frequency is 50 hz and the motor is 60 hz, you may have to reduce the voltage further, depending on the type of motor. The only safe way to go is buy a transformer.

There are several possibilities, none of which is guaranteed, that might be possible. Luck also has a big factor in this.

1. If the motor is not a tiny one, there is a chance that it is dual voltage 120/240. Many modern motors, about a 1/4 hp and up, are dual voltage.

2. Depending upon where you live some homes are wired for 120/240 single phase. If this is the case make some changes in the circuit breaker panel for the circuit feeding the motor.

3. If the motor is very small, a high wattage resistor could be placed in series with the motor. This will generate a lot of heat though.

4. If you have an identical motor run them in series is a possibility, not guaranteed though.

5. Check with a motor rewinding shop and see if the motor can be rewound. Unless the motor is 1 hp or more it could be cheaper to buy a new motor. Also ask them for any recommendation for what they would do to solve your problem without rewinding.

6. Buy a used transformer. If there is an "electronic junk yard store" with used equipment ask them. A ham radio operator might be able to help you locate one.

Running a 120v motor at 240v is not recommended. Depending what type it is it could self-destruct very quickly with a fire works type display. Make sure your insurance is paid up.

Good Luck, Old Salt

if the energy waste is out of concern you can use a series resistance to drop the voltage till required value .

otherwise you have to use a transfer .

Option 1

Call the fire department and report a fire at your home. Plug the motor into 220V and switch on. Don't panic about the subsequent explosion and fire, the fire department is already on it's way.

Option 2

Buy a 220/120v transformer

Option 3

Buy a new 220V motor

In certain 240VAC countries, building sites must use tools with 120VAC. They use safety transformers, they can be cheap to buy secondhand on ebay or car boot sales.

You do not allow us to know where you live, that is negative for us and for you personally, please change your settings.

I assume from his name, he is from India.

And what sort of motor is it?

Here is the other question from out motor man.

I wish there was more information . . .

This must be single phase motor. We have 220 V for single phase here.

what type of settings may I change?

This is what you HAVEN'T TOLD US UP TO NOW!!

Which implies to me that you are not an EE for example, nor are you an electricain either....

Try doing/posting the following:-

You can change your personal CR4 settings to tell us where you live and work, the country will be enough usually. Some of us give Latitude and longitude as well....

You can tell us if you are in an AC or DC mains area for house electricity.

You can tell us your frequency of the mains voltage.

You can tell us whether the motor is AC or DC. What frequency if AC?

You can tell us, if DC, is it a brush or brushless design of motor.

If AC with brushes, is it a universal motor or not.

You can tell us its wattage or running current.

You can tell us if an AC motor, single or 3 phase.

If single phase, with or without starter field winding and capacitor. Furthermore has it a centrifugal switch or not!!

Picture of motor plate.

Model number and manufacturer.

I am sure that I haven't noted everything, but this should give you an idea of what WE need as a start to help YOU!!

Otherwise its just a guessing game......

Depending on the rated power and load type you can use a capacitor in series. It can be cheaper and lighter than a transformer.

Your question suggests that your not from an electrical background (forgive me if I'm wrong). Going on this assumption, what makes you think this is an AC Motor and not a DC Motor. As you've supplied us with very little information.

How often is DC used to supply towns nowadays? Very, very seldom. He mentioned that in a way, but his English is not so good:-

I have a motor the rated voltage of that motor is 120 but in my home there is 220v supply I want to run that motor in my home but how I don't have transformer to adjust voltage but how can I operate

So the chances are huge that he was talking AC. Millions to one for DC?

Well considering we have no idea where he has obtained this motor from, why should we start making assumptions. If he has gone out and purchased this motor from a shop, why then has he been supplied with a motor of a voltage that has no relevance to the supply voltage of the country he lives in.

This motor could've come from anywhere i.e. from his place of work, where there could be a very high chance that it could be DC .

The posts we make will have already alerted him I guess.....

I think you should look at your breaker box, find out if the 220V AC has two "hot" leads, that make up the 220V. Either one of the leads should be ~115V AC with respect to ground (neutral). Install a new circuit on this, making sure that (1) you get the desired voltage of ~120 VAC, (2)the neutral and ground are firmly established, (3) right before you do this, bail out, and hire a local electrician to fix it right, (4) order a new 220V AC motor to replace the one you about to let the smoke out of.

All electricity is smoke, failures are just leaks of the smoke.

That is true for a small part of the world live, usually with 60Hz.

The major parts of the world are 230VAC and are 50Hz.

The type of connection you describe is not found where 50 Hz is as far as I am aware, though a possible isolated one could exist....see Madagascar and part of Japan!!

So then, Andy, I removed all doubt. Forgive me for being Anglo-Centric. America rocks! The rest just roll. America uber alles.

Can you run that by me in English instead of American, it simply did not make sense and I don't want to get offended for no reason now do I?

Exactly why I asked for "clearance"...Thanks!!

I always feel that its best to write as clearly as possible first time around!! But it is not easy for all I know!!

Especially for those who do not have English as a first language.

Americans?

Have a great day in spite of my joshing!!

One of my friends has English as second language, yet taught at an upscale Eastern Seaboard of U.S. engineering school for a number of years. He speaks Choctaw as first language, and also Chickasee.

I also speak Chick-I-See.

LOL!!!

"Any-Chick-I-See"?

something like that, I suspect.
