will a 110 volt motor turn 2x as fast if ran on 220 volts

Long story short, I bought a pizza place. The conveyor pizza oven is way louder than spec. Factory spec is 80 decibals. This oven is running at 105 decibals. The noise sounds like mass amounts of airflow. Like a jet engine on crack

Now I didn't check the wiring yet but in my sleep tonight I wondered if the install guy somehow wired this 110 volt oven up to 220 volt could in theroy the 110 volt motor run twice as fast making it louder. If it didn't fry the motors ??

Sounds stupid but I can't sleep and I'm thinking about this a lot now cause it hurts my ears

It's possible, how many wires come off the motor?
what is wired into now?

No. A 110v motor not designed to run on 220 will burn that thing up.

I highly doubt that it is a 110 motor, being a commercial unit it is probably 220 or 240.look inside there should be a schematic which will give you the specs.
It should also be marked on your fuse panel,get a meter and check it.
They do make 110v/220v motors it depends on how you wire them

I would call the manufacturer and explain the isue the should be able to tell you what is wrong

not sure what kind of motor you have there. But from my experience working around baggage conveyors in airports, our motors are three-phase motors (three hot wires and a ground) and they are all rated for multiple voltages. All US airports uses 480V and Canada uses 600V. Now, it doesn't mean the motor spins faster in Canada, they all spin at 1750RPM, but only that the same motor in Canada draws less current.

Most industrial motors have a metal nameplate on the side of the motor stating all the info you need. If the motor is multi-volt rated, it will say 480/600v, and the amp rating will also say 3.6/2.4 amps etc.

If the motor is not rated for the voltage you are supplying, it won't last very long and will run very hot - if it runs at all.

Usually when a motor goes bad, it won't make much noise. It just runs really hot and then trips the overload protection. Noise is usually from things that are attached to the motor, like a v-belt or chain, etc. There are cases of bearing failure within the motor which will make noise, but most motor failures are not caused by the bearing.

You seem to have a lot of issues with both physics and numbers.

we had a shop class in school and had to assemble a 5v electric motors.

a genius who wired the classroom put identical outlets for 5v and 220v next to each other so i accidentally plugged 5v into 220v. it spun up real fast and before i could even yank the cable the whole fucking thing blew up in pieces right in front of me. Got an F for almost killing bunch of people with flying metal pieces. lol

we had a kid who put too much voltage to a capacitor and blow it up like a firecracker.

That's what you get for cooking pizza in a conveyor oven.

So you make 1826 pizzas per location each day? That's a lot of pizzas!

I think he meant $2 mil worth of pizzas. So, maybe 125 a day per location.

Voltage has no baring on speed, at least in an AC motor, It depends on how many poles in motor and how they are wound. DC motor do speed up with voltage until you over voltage them and they burn up. The Motor could have different wiring configuration to allow the speed to be changed, so yes it could have been wired up incorrectly. Also fan noise many time has more to do with air flow, when the air flow is restricted either on the inlet or outlet it can create back pressure on the fan causing increase noise.
