Answer / elangeswaran

the motor speed will increase the increase in frequency
lead to more heating due to iron and hysterisis losses as
they are directly propotional to frequency. the mechanical
design also will not support the high speed

Answer / lalchhotex

when we increse frequency of motor through drive in this
condition motor RPM also increase

Answer / prasad bhagwaty

if drive freuqvency increased then motor speed incresed but motor over heated

Help need in transformer !? Hello Friends The parameters of 2300/230 v 50hz t/f is R1=0.286 ohm R`2=0.319 ohm Rc=240 ohm X1=0.73 ohm X`2=0.73 ohm Xm=49.2 ohm Secondary Load impedance ZL=0.387+J0.29 solve the exact equivalent circuit with normal voltage across primery.. I know every thing but i cant find CURRENT I1=? and I`2=? Please help me give solution or only Formula please please...
