At rst, the rated values of the voltage, the power, the frequency and the number

of pole pairs are specied. Then the base values are computed. If the IM param-

eters are given in pu, pu = 1 has to be put; if they are given in SI, pu = 0 has to

be put. In the rst case, the parameters are used directly, and in the second one,

a computation of the parameters in pu is carried out. As a result, the parameter

values are formed in the workspace, and simulation can be carried out. It is reason-

able to write down the command run IM_MODEL_6term in the window Model
