If these are the exact voltages that you need you will need an auto transformer to obtain these voltages. If these voltages are nominal voltages and are of a three phase four wire configuration, the 220 voltage can be obtained from the three phase legs to the neutral (ground) connection. The equation to use is 400/1.73 = 231 volts.
One method is to use an auto transformer and use the 220 volt tap.
With a transformer or motor/generator set.
Use a step down transformer with a turn ratio of 2:1.
Use a step down transformer.
by using a step down transformer
By using a suitable transformer
The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347 volts. This lower voltage is present on any of the three phase legs of the three phase system to the neutral which is grounded on a wye connection.
any one of the three line to neutral is 220 volts
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.
If the Peak to neutral voltage is 220 volts, the root mean square voltage is 155.6 volts (sqrt(220)).
You should be able to use it as is (assuming the plug matches your outlet). It will just run a little bit cooler at 220 volts vs. 230 volts.

3 phase 220 volt submersible motor convert to 440 volt
No.
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
Answer for UK and countries running a 50 Hz supply service.The voltage potential of 380 volts is not common to North America.It will probably be difficult to tap into the plug to get the voltage.If you have a three phase 380 volt supply from a source then you can obtain a single phase voltage of 220 volts from it. 220/380 is a wye voltage connection. 380 divided by 1.73 will give you 220 volts. L1 - N = 220V, L2 - N =220V, L3 - N = 220V. L1 - L2 = 380, L2 - L3=380, L3 - L1 = 380.
No 380 volts is too wide a spread to use a 220 volt motor on.

The formula you are looking for is I = W/E. Amps = Watts/Volts.
Yes, that's exactly what it's designed to do.
You need a 110 v to 220 v transformer, which will be inexpensive for supplying an alarm clock. That steps up the 110 v suppy into 220 v for the clock.
you don't. you just take and use 120 volts from the 220. At least that's what I'd do.
