Abstract
The training of technicians in maintenance requires the use of
signals produced by faulty machines in different operating
conditions, which are difficult to obtain either from the industry
or through destructive testing. Some tasks in electricity and
control courses can also be complemented by an interactive
induction machine model having a wider internal parameter
configuration. This paper presents a new analytical model of
induction machine under fault, which is able to simulate
induction machines with rotor asymmetries and eccentricity in
different load conditions, both stationary and transient states
and yielding magnitudes such as currents, speed and torque.
This model is faster computationally than the traditional
method of simulating induction machine faults based on the
Finite Element Method and also than other analytical models
due to the rapid calculation of the inductances. The model is
presented in Simulink by Matlab for the comprehension and
interactivity with the students or lecturers and also to allow the
easy combination of the effect of the fault with external
influences, studying their consequences on a determined load
or control system. An associated diagnosis tool is also
presented.
