Since V=K*B*frq [V= primary supply voltage -approx.
equal to E-emf]; B=magnetic flux density ; frq=frequency]
then if frq=5 Hz and V=constant B[5Hz]=10*B[50 Hz].The no-
load[excitation] current will be more than 300% rated
current.
You have to reduce the voltage to 10% from rated at 50 Hz
in order to get the same B.

Some times to change of DOR of a motor, interchange of R & B is not effected and RYB take same current, but interchange of R&Y is effected ie change the DOR. My doubt is what is the problem in motor and how it is happen.
