whatis knee point ?

Answer Posted / raghavendran

Knee point refers to a point in the saturation curve drawn
between voltage and flux.It is drawn keeping Flux in the X
axis and Voltages in the Y axis.The Knee point falls below
saturation level.Till Knee point the Flux - Voltage relation
will be linear.After knee point,any increase in flux will
not cause proportional increase in voltages.
