As long as they're the same voltage, yes it will, but probably not for long. A lot depends on what type of appliance you're using. For instance, if it's an electric stove, you'd probably be OK, but if it has a clock, expect it to run slow. And even that too, dependfs on what type of electric stove it is. The problem is that at the lower frequency, the device has to draw more power in able to do the same amount of work that it would at 60 Hz. Because of that, some motors, electronically controlled devices and the like, tend to overheat as a result. For a window fan, it's probably no big problem (although I'd keep an eye on it until I knew for sure) but for something that's `frequency dependent', like a refrigerator compressor, I'd think you'd just be asking for problems. Usually during the day, voltages and frequency of the U.S. system varies in both frequency and voltage. A `brown-out' usually happens when the voltage falls below 80 volts, as compared to the nominal 117 volts. But too, so does the frequency. Tis is mainly because of industrial usage during the day, along with air conditioners and the like. Late at night though, it's usually closest to where it's supposed to be. Does it work? Will it work? Yes. The question is: For how long.
I've seen it done. Be sure you have the correct voltage going to the motor. A 50 Hz motor was probably used in the UK, or other parts of Europe. They use 240V/50 Hz. So your motor will probably need 240V too. Check the motor's nameplate.

Yes, As long as the v/f ratio is same 460/60 =7.6 and 380/60= 7.6. But of course you have to ask the minimum speed this motor could run since it will cause overheating of winding when using VFD.
This is a common question and unfortunately the answer is very complicated. As the frequency of the motor drops the current that flows in the motor rises so it is important to drop the input voltage to avoid damaging the motor. This is usually done in a linear fashion so this 60hz motor running at 50hz should be run at 50/60*480V = 400 volts. So no this motor cannot be run on a 50hz 440v system. It is also important to realise a 60hz motor running on a 50 Hz supply will rotate at 3000RPM not 3600RPM, so it will be slower as well. Finally due to the voltage being less the motor will not be able to produce the same power as it could on a 60hz supply, so it usually isn't worth it anyway.
Yes, the motor will be ok but it will run 20% faster and this might damage the equipment it is driving.
It is an extremely expensive way of utilizing the deep fat fryer. You should look into changing the heating coils in the fryer to utilize the new voltage. That said it can be done.
Should work at nearly full power as long as the polarities of the 4 pin plug are in sync and it is a 3 phase 50Hz motor. Do a regular temperature check under full operating conditions for the first hour to ensure speed is enough for cooling.
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
There should be no problem at all.
The speed of a single phase digital meter 1600mp or kWh 50HZ can be reduced. By decreasing the voltage to reduce the speed of the single phase digital meter the motor is to decreased in speed meaning the consumer load will be decreased as well.
Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?
no

It would probably spin, but I don't know if it'd last very long. First, the speed of AC motors typically are dependent on the frequency ( 50 Hz or 60 Hz) so the motor would be trying to spin 20% faster than designed. Also, because of the higher voltage, you would have more current running through the motor windings (wiring) than designed. These 2 conditions would cause overheating of the bearings as well as the wiring inside the motor.
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
It will probably run but not correctly. Low voltage will cause the motor to draw less amps than it's designed to. It will not reach its rated RPMs and such slow operation may shorten its operating life.
Depends on the current rating which should be on the motor.
