## Induction motor model in rotor flux frame with three phase sinusoidal excitation (Scripts) Publisher's description

### This model simulates three phase induction motor model in rotor frame of reference.

This model simulates three phase induction motor model in rotor frame of reference.It is helpful in simulation of induction motor drives.
Electrical system equations:

Vs = Rs is + (1/wb) (dfs/dt) + wf M(pi/2) fs

where the variables is, vs, and fs are 2-dimensional space vectors and M(pi/2) represents a 90 degree space rotator namely [0 -1;1 0]

wf = wm + wr;
wr = Rr Lm/Lr (iqs / fdr)
1/wb Lr/Rr (dfdr/dt) + fdr = Lm ids
fqr = 0

fs = Ls is + Lm ir
fr = Lm is + Lr ir
Ls= Lm + Lls;
Lr = Lm + Lrl

Mechanical system equations:
Te = 2H (dwm/dt) + Bm wm + Tl
where Te = Lm/Lr (iqs fdr)
