Specific Magnetic Loading using Output Coefficient AC Formula

Specific Magnetic Loading = (Output Coefficient AC*1000)/(11*Specific Electric Loading*Winding Factor)
B_av = (C_o(ac)*1000)/(11*q_av*K_w)

What are the factors that decide the choice of specific magnetic loading?

There are 3 factors are used to determine the specific magnetic loading. They are maximum flux density in iron parts of machine, magnetizing current and core losses.

What are the effect of higher value of specific magnetic loading?

Higher the value of q larger will be the number of armature of conductors which results in higher copper loss. This will result in higher temperature rise and reduction in efficiency.
