If a +/- 10% service voltage variation is allowed then the 380 volts RMS "nominal" voltage could in fact vary between 342 volts and 418 volts.
Whether or not it would be safe to run a 3-phase motor, which was designed to run continuously on a 380V service, on a 415V service will depend on how closely the actual voltage which is being supplied stays to 415V because, allowing for a 10% variation either way, the actual service voltage could vary between 373.5 volts and 456.5 volts.
The lower voltage would be ok but the higher voltage would be too high such that there could be a risk of the motor overheating and/or catching on fire if the circuit breakers don't trip to shut off the current.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
Can a 440 - 480V 60Hz motor run in a site with 380V 60Hz supply If No how can it work?
The motor will run, probably at nearly the same speed, but it cannot supply the same mechanical load. If it can be run on a lighter load, proportional to the voltage, it should be OK.
What is impact ampere in 50Hz motor connected to 60Hz?
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
Can you run 480V motor on a 380V system Have is 480v 60hz 3 phase equipment and moving to a country with 380V 50HZ 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.
The motor states it is 230V single phase to operate. Does that mean you need two 120V lines in and just a ground with no neutral?
Answer for USA, Canada and countries running a 60 Hz power supply service. The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get a 240 volt output because L1 and L2 are adjacent to one another. If the rating plate on this motor says 230V and it has a brown wire (the 230V "hot" or live"), a blue wire (the "neutral") and a yellow/green wire (the "earth" or "ground") it was designed for use in Europe or other world areas which use a 50Hz supply. Those wires mean it requires just one "hot", running at 230V and a neutral. In 50Hz areas that neutral is connected to earth (ground) back at the breaker panel. If you are planning to use it in a 60Hz area, such as US or Canada, it would be wise to determine exactly how the ground wire is wired inside the motor. Check it by using a test meter: if it was made in the past 30 years or so the earth/ground wire should be connected only to the frame of the motor and should not be connected to the neutral wire in any way. If you are sure that is the case, then you can use the motor but only if you do not use the 60Hz supply's neutral, which is the white wire. Connect the motor's brown wire to one of the 60Hz supply's "hots" - say the red. Then connect its blue wire to the 60Hz supply's other "hot" - say the black. (It doesn't actually matter which hot goes to which.) Be sure to connect its ground wire to the 60Hz supply's ground, which is green or bare wire, and do not connect the 60Hz supply's white neutral at all. Just leave it blanked off inside an insulated connector or wire nut.If it is an old type of 50Hz motor it might have a red (or, in newer models a brown) 230V hot wire with a black (or, in newer models a blue) neutral wire with plain green (or yellow/green) ground wire. If, using a meter, you find the motor's ground wire is linked both to the frame of the motor and to its neutral wire, that link to the neutral will have to be cut before you try to use the motor. Leave the ground wire connected only to the motor's frame. If you don't make sure that link is cut so that the neutral is no longer connected to the ground wire, you will have big problems when you hook up the motor because, back at the breaker panel, the 60Hz supply's neutral is connected to the ground, so if that link within the motor had not been removed, it would cause a short to whichever 60Hz hot (red or black) you connected to the motor's neutral wire! Note: if the motor does not have brushes running on an armature then it is a squirrel cage or similar type induction motor, which means that, running on 60Hz, it will spin at a speed 60/50 of its rated design running speed. That is 20% faster than it would spin at 50Hz, so it would be wise to check that the higher speed is suitable for the equipment you want to use the motor for.

Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.
What is an ac motor?
An AC motor is an electric motor that runs on alternating current, like household electricity, as opposed to a DC motor that runs on direct current from a battery. Most AC motors work from the mains supply, which has a frequency of 50Hz in the UK and 60Hz in the USA. Other types are available that work like stepper motors and need a specialist supply to run them.
How can you run a 220v 3-phase 60hz motor on a 380v 3-phase supply?
Not advisable, the voltage differential is too great.
How can you run a 380VAC 3-phase 50hz motor on a 220VAC 3-phase 60hz supply?
To run a 380VAC 3-phase 50Hz motor on a 220VAC 3-phase 60Hz supply, you would need to use a voltage converter to step up the voltage from 220VAC to 380VAC. Additionally, you may need to adjust the motor's parameters to account for the difference in frequency between 50Hz and 60Hz, such as adjusting the motor's speed rating and ensuring the motor does not overheat due to the increased frequency. It's important to consult an electrician or motor specialist to ensure safe and proper operation.
Can you run a 460v 60hz motor to a 480v supply?
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
How do you connect a 460V 3 phase motor 60Hz with 380V 50Hz 3 phase supply?
You can use a voltage converter to step down the 460V 3 phase motor to match the 380V 50Hz supply. Make sure the converter can handle the motor's current requirements. It's also advisable to consult with an electrician to ensure safe and proper installation.
Can i use an American Apple TV in Australia?
No. Australia's electricity supply is 230 volts at 50Hz... america's is 120 volts at 60Hz.
How do you connect a 230volt 60Hz air conditioning unit with one phase wire to a 240 volt 60Hz two phase south American supply?
Treat the USA 2 Phases as 1, its called split phase, instead of Line and Neutral, you ahve two phases but they deliver 240v, this will not hurt a 230v machine as the chances are that you are NOT getting 240v supply at the delivery point anyway. As long as the machine si 60Hz and supply 60Hz, you will not have a problem
How can you determine if an electric motor is 50HZ or 60HZ if there is no name plate?
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.

What is the result of running a 460 volt 3 phase 60hz motor with 415 volts 3 phase 50hz?
It will run hotter. It will run slower, about 83% of nameplate speed. It will draw more than the nameplate current. You will only be able to get about 3/4 of rated horsepower. If the motor is loaded to more than this, it will not live very long.
