b/c if voltage decreases therefore the current is increases
due to p=v*i & hence if current is increases therefore the
magnetic flux will also increases & hence there is good
magnetic strength will occurs
It is the requirement of the machine.we can either operate
in 440 or 220 or even in 110 volts.The voltage depends upon
the motor,circuit and other loads related with the machine.

What does 380 volts between phases mean?
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
Can a 240 Volts delta motor run on 440 Volts star connection?
If it is a 240 v delta motor it needs a 240 v three-phase supply, which has 139 v between line and neutral, so 440 v would not be acceptable.
380v motor on 415v?
Answer for European SystemsThe nominal line-to-line voltage used for single-phase supplies in Europe is 400 V. In the UK, this voltage is allowed to vary between -6% and +10%; in other words, it can vary between 376 V and 440 V. So it would be quite acceptable for a 380-V and a 415-V motor to operate on this system.

Relationship between work and voltage?
Work W=VC where V is voltage and C is charge. WORK is power power= I X V I=CURRENT V=EMF
Will a 50 hertz 380 v motor work on 60 hertz 440 v?
no it will start to smell after a few min.
