The squirrel cage induction motor has been and actually is the rotating electrical machine most used. The origins of the success are the robustness that represents to have a rotor without windings and the low relative cost with respect to other machines.
From the beginnings of the last century, directly connected to the network, to our days, connected by means of static converter, there is a great variety of dynamic performance drives.
The interests in the modelización and quantification of the parameters of the motor have been evolving of parallel form to the technological development.
In the present thesis a balance between the different levels of exigency, the demanded benefits from the drive, the practical costs of implementation and the restrictions are accounted to develop a methodology for the determination of the electrical parameters of the induction motor. This methodology is based, in the measurement of the viable thing practically, in the initial tests or Self-Commissioning.
In the first place the different models susceptible of use are evaluated.
The existing models are used complemented with an unpublished model for the magnetization characteristic in low magnetization situations: the modified polynomic model. Also a new model for the converter working in open loop and DC injection is introduced.
Considering the general restrictions that the industrial reality imposes: not to use more sensors neither the more signals that or implemented in a commercial converter, process automated and automatic with the smaller possible human intervention, wide size rank of motors, to avoid or to diminish the movement of the motor, and to imple
