Resumen:
This work presents, demonstrates and
analyzes a property that relates the transient
response of stator and rotor currents to the speed of
induction motors and their parameters. The
straightforward application of this property allows
determining the rotation speed of the motor and
detecting a failure or variation of its parameters.
This property is demonstrated analyzing the
induction motor modeled by two parts: one linear
and another non-linear. Based on the operating
principles of induction machines and the theory of
differential equations, a hypothesis is stated on the
behavior of currents in the transient state. Then, by
symbolically computing the eigenvalues, the
hypothesis is verified so that it validates the stated
property.
