comp_skin_effect_resistance(self, freq, T_op=20, T_ref=20, b=None, zt=None)

Compute the skin effect factor on resistance for the conductors from “Design of Rotating Electrical Machines”, J. Pyrhonen, second edition All parameters are defined p.270 / 271

Parameters:

• self (Conductor) – an Conductor object

• b (float) – Slot width [m]

• zt (int) – Number of turns in series per coil

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

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

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

Returns:

kr_skin – skin effect coeff for resistance at given frequency and temperature

Return type:

float
