difference in motor and transformer used for 230V, 60Hz system and 415V, 50Hz system
(OP)
What is the difference in the design of transformer and motor (core and windings) in US (230V,60Hz) and India (415V, 50Hz)?





RE: difference in motor and transformer used for 230V, 60Hz system and 415V, 50Hz system
E=4.44*N*f*A*B
E= electro-motive force
N= turn of winding
f=frequency
B=magnetic flux density
A=unit of area
if f1>f2 and E2>E1 then it must be n1<n2 or A2<A1
therefore US devices are larger(A1>A2)
RE: difference in motor and transformer used for 230V, 60Hz system and 415V, 50Hz system
(N*A*B)US < (N*A*B)India
If B and N are same
then AUS < AIndia
therefor U.S. devices are smaller

I think, N can be determined by A, because The amount of copper usually is same, then for example if A2>A1 then N2<N1
(N)us<(N)ind then (A)us>(A)ind
