comp_skin_effect_inductance(self, freq, T_op=20, T_ref=20, b4=None, h4=None, zt=None)

Compute the skin effect factor on inductance for the conductors from “Design of Rotating Electrical Machines”, J. Pyrhonen, second edition All parameters bc, h4, z4, are defined in Fig(4.14) p.249

Parameters:

• self (Conductor) – an Conductor object

• freq (float or ndarray) – electrical frequency [Hz]

• T_op (float) – Conductor operational temperature [degC]

• T_ref (float) – Conductor reference temperature [degC]

• b4 (float) – Slot width [m]

• h4 (float) – Slot height [m]

• zt (int) – Number of radial adjacent conductors

Returns:

kl_skin – skin effect coeff for inductance at given frequency and temperature

Return type:

float
