A new parameters determination method for
squirrel-cage induction motors is presented. As a main contribution,
the method uses the instantaneous electrical power and
the mechanical speed measured in a free acceleration test to
estimate the double-cage model parameters. The parameters are
estimated from the machine impedance calculated at several
points: (1) at speed points where the double-cage effect is significant,
i.e., between the zero speed point and the maximum
torque point, the machine impedance is evaluated by the instantaneous
power method and (2) at speed points where the doublecage
effect is not significant, i.e., between the maximum torque
point and synchronism, the machine impedance is evaluated by
a dynamic model based linear least square method. The proposed
method has been applied to obtain the parameters of
three motors tested in the laboratory. To check the method accuracy,
the steady-state torque- and current-slip curves predicted
by the estimated parameters are successfully compared with
those measured in the laboratory. [-]
