Iron losses are the fixed losses in an electric motor.These
are also known as "fixed losses".These are:
1> Eddy current losses
2> Hysteresis loss
To overcome eddy current loss the core is built is in
laminations while to overcome hysteresis loss, the core is
made of stainless steel laminations,i.e.,hysteresis loss is
a property of the material of the core.
Copper losses are the variable losses equal to sq. of
current X R.
