介绍
CoreLossCoeifficient用于拟合电工钢的BP曲线。
原理
Under sinusoidal flux conditions, core loss is computed in the frequency domain as follows:
$$
P_v=P_h+P_c+P_e=K_hf(B_m)^Y+K_c(fB_m)^2+K_e(fB_m)^{1.5}
$$
For a material with anisotropic core losses, the coefficients Kh, Kc, Ke, and Y have different values in different principal directions, that is, (Khx, Khy, Khz), (Kcx, Kcy, Kcz), (Kex, Key, Kez), and (Yx, Yy, Yz) in (x, y, z) directions, respectively.
where
Bm is the amplitude of the AC flux component,
f is the frequency,
Kh is the hysteresis core loss coefficient,
Kc is the eddy-current core loss coefficient, and
Ke is the excess core loss coefficient.
Y is the power of Bm for hysteresis core loss.
