sewing machine energized

We just bought a new sewing machine and discovered it has an energy field--up to 20 inches away. I happened to be using a pen-type voltage detector (because the light on the machine is erratic), so it's useless to track down a loose connection. I'm a novice but have used the detector many times without encountering a field. I plugged in the old machine and it also sets off the detector, but only up close to the motor area. I checked the wall plug and it is grounded properly. The new machine was made in Thailand and has UL listing. Instructions say to unplug when not in use and not to use outdoors. Is this unusual or am I just now learning something? Is it safe???

All electrical devices radiate an electro-magnetic field when there is power running through them.

Most devices incorporate some degree of shielding so that other electrical devices are not bothered, and so that people are not radiated (although they will never mention this last reason).

I am not familiar wiuth sewing machines I have no idea if they lean toward putting out MORE or LESS energy than other devices.

My suggestion is to not use the machine if you are pregnant.

Thanks racraft for the advice. It was learning for me, because I discovered the TV has a detectable field also, though closer. The light?--I just pushed the plug more securely into the machine--so simple!

This is why I say that "no contact" testers are not good for life safety.

good for troubleshooting, but once you believe you are right, use a contact tester to be sure.

No sewing... No TV... Wow, this could be an eternity.

To test the appliance, use an ohm meter, or better yet, a special ohmmeter called a Megger.

Unplug to avoid accidental injuries and I doubt it is rated ofr outside usage. The terms "weatherproof" and "sewing machine" don't seam (intentional misspelling) to go together.

If you have a non contact tester triggering at 20 inches, I would be a bit concerned. Although it does not mean something is actually wrong, this is a strong EMF, especially since you have compared this with other sources.


Did tightening the light alter the tester situation?
