This consists of a MatLab function that is based on the work of M. H. Haque, in which he describes how to estimate the parameters of an induction motor based on the data sheet.
The function is defined as follows:
function [X1, X2, R1, R2, Rm, Xm] = induction_parameter(hp, V, pfh, nh, pff, nf, sf, Tfl, Tst, tol)
Input:
- hp, nominal power in hp
- V, voltage line-ground
- pfh, power factor of half load
- nh, efficiency of half load
- pff, power factor of full load
- nf, efficiency of full load
- sf, slip of full load
- Tfl, torque of full load
- Tst, starting torque
- tol, tolerance
- X1, stator reactance
- X2, rotor reactance
- R1, stator resistance
- R2, rotor resistance
- Rm, exitation resistance
- Xm, excitation reactance
Different test are implemented and sum up in test folder which are based on WEG Datasheet Motors.
