The mathematical model of an electric machine represents all the equations that describe the relationships between electromagnetic torque and the main electrical and mechanical quantities. The mathematical models with concentrated parameters are the most popular and consequently employed both in scientific literature and practice. The equations stand on resistances and inductances, which can be used further for defining magnetic fluxes,
electromagnetic torque.
% Parameters of a typical induction machine.
Rs=0.435; %Stator resistance
Rr=0.816; %Rotor resistance
Lls=0.002; %Stator inductance
Llr=0.002; %Rotor inductance
M=Lm; % Mutual inductance
P=4; %Number of Poles
J=0.089; %Inertia
B=0.01; %friction coefficient
Tl=0.5; %Load torque
Lss=0.0713; %Lss = Lls + Lm
Lrr=0.0713; %Lrr = Llr + Lm
