Reducing the start-up transients of an induction motor
The steady-state characteristics of devices with periodic excitations – such as motors and generators – are often of interest. Unfortunately, the large time constants can have start-up transients that take a considerable amount of time to die out. One example is voltage-driven coils with large inductances.
The start-up response cannot be skipped by simply starting the simulation at a later time. However, there is no need to wait through the slow start-up response either.
There are a number of techniques to significantly reduce the duration of start-up transients using the right initial conditions with MagNet. These powerful features are applied to the simulation of an induction machine. These methods can all be automated by scripting as well.Open Report (Model 0198)
