Not a juiceatrician, but should be OK, Your house is likely less than 120, Usually anywhere between 110/117. Might get a Multi V meter and check it.

not an electrician -- but yes it will run fine. if the voltage is truly 120 it will pull less than .6 amps. house power has been called everything from 110- 120 volts. You can even run that one on 120 dc volts.

Yes

House running at 116 Volts

not an electrician, I am an electronics technician ,110 is what they used to call normal wall power or grid power now it is called 120 it is likely someplace between the two and it will be just fine wound motors are every forgiving

I also had a similar singer and it worked just fine on current ac US grid power

My mom has rehabbed a ton of old sewing machines. The motor should be fine on house voltage. Make sure the cord is good. Maybe run it outside first, just in case the magic smoke goes bye bye.

What kind of machine is it on?

I've noticed that 110 is no longer 110 or 220 is still 220. Everything new is 120 or 240. I wondered what was up with that.

It's a 1910 Portable Singer sewing machine. Has the exposed rubber belt pulley. Wiring looks a little worn in some spots.

it hasn't been 110 since before I got my first meter in about 1989

not sure it ever was I think 110 was a minimum acceptable and then the nomenclature turned to max expected

109 and below is starting a brown out condition

114-117 is very common I see up to about 123 at times

High voltage is better than low voltage. I deal with a ton of 480 volt 3 phase motors and want 490-500 rather than 470 volts

110 is closer to the voltage on the wire 120 is the rating that the components will operate safely at
Hence 110 outlets or 220 plug in. But ratings are 120 and 240 volts
Really want to jack with someone mention 180 wild leg or 208 circuits !

Anyone notice that motor is also DC ?

Green around here most circuits will test around 106-112. No brown outs that’s typical

Your allowed 10% on voltage variation to what’s rated on name plate of motor.
I have my doubts your motor was made in 1910. In this country Canada, we where on 25 cycle at that time and I would imagine the states was too. The change over happened around 1940-50. My dad worked for comstock doing the motor change overs on farms that’s the only reason I know that.

Voltage should be within 10% of the motor's rating. Motor having a range of acceptable voltage is weird today but... Motor rated at 110V > 10% is 11V > could run on 110V +11V = 121V. I'd go for it.

I was wondering the same thing. Not sure I’ve seen that before and trying to think it through.

Did a little research . NOT a battery power also. It has to do how the electronics deliver the power inside of the motor.

just don't get your 110/120 relay on the wild leg , it makes for a short life of the relay

had some deep fryers at the church they made it about 2-3 fish fries before we realized some outlets were wired with the hot/wild in the wrong leg


they call 180 , 177 at some of the places I do work they want to know if your equipment can run 177 because they always seem to have extra space in the 177 rack

It's fine.

120 is the present nominal voltage. But depending on load during peak use hours in your area it will vary from that...

I'd worry more about the state of the insulation and whether or not things are grounded.
