| Stdio-Wcalc: air_coil_calc air_coil_calc - Single layer air core solenoid inductor analysis ## SYNOPSIS air_coil_calc N len fill AWG rho dia freq flag ## PARAMETERS ### INPUT PARAMETERS N : Number of turns len : length of the coil (meters) fill : ratio of coil length to closewound length AWG : wire size (American Wire Gauge) rho : resistivity of wire (ohm-m) dia : inside diameter of coil (meters) freq : analysis frequency (Hertz) flag : used to calculate coil length. flag=0 : the length given by len is used. flag=1 : the length is calculated from the wire size, number of turns and fill input. ### OUTPUT VALUES L : calculated inductance (Henries) Q : calculated quality factor SRF : calculated self resonant frequency (Hertz) len_out : length used for the analysis (meters) fill_out : fill used for the analysis lmax : maximum (closewound) inductance ## DESCRIPTION Function to analyze the electrical characteristics of a single layer, uniformly spaced, air core, solenoid inductor. The physical dimensions of the coil are given as inputs and the inductance, quality factor, and self resonant frequency are calculated. ## EXAMPLE
