It would not be immediately dangerous but there is a possibility of overheating with the 9% overvoltage so it isn't a good idea unless the motor is lightly loaded and watched very carefully. The safe voltage range should be marked on the motor.

What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?
Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
Can a 380volt's 3 phase motor can be converted to 230volt's three phase motor?
Only if you want to damage it. "277" Volt 3-phase will usually mean 277 from each phase to neutral, and 480 from phase to phase. By "230 3-phase", you likely mean 120 phase-to-neutral, and 208 phase-to-phase. If you really mean 230, then you are probably NOT talking about a three phase motor.
How do you calculate 3 phase power for a motor that draws 22 amps per leg it is a 480 3 phase motor do you use 480 x 22 or 277 x 22?
1.73*480*22
How many amps will a 50KVA 3phase bank carry on 277 - 480 volts?
50 kVA is 16.667 kVA per phase and you divide that by the phase voltage. Current = 16667 / 277 = 60 Amps
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
Can you connect a 460volt 3 phase motor to a 480 volt 3 phase system?
The systems are one in the same. Yes.
Can you run a 570 volt motor on 480 volt three phase power supply?
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?
Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
What is the result of running a 480 volt 3 phase 60hz motor with 415 volt 3 phase motor?
If they are in different rooms or side by side in the same room, and not connected together mechanically, there should not be a problem.
Can you replace a 480-240V 3-phase motor with a single phase motor as a temporary replacement or will it burn it out?
Yes, you can, and it won't burn out IF>>> the horsepower rating is the SAME. Pay attention to wiring and motor rotation. Also check the voltage: the motor voltage must be the same as the voltage between two hots of your 3 phase system. You will only use two hots as this is a single phase motor.
What is the start up amps on a 200 hp 3 phase 480 volt motor?
i have 200 hp motor what i need cable size in 100 feet distance
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
If you had 277-480 3phase power feed can you still use it to power IT equipment rated at 110-120V?
yes
