Visualizing Class Separability - Independent Component Analysis

-

The Independent component analysis (ICA) was able to separate each of the 5 classes very well. ICA was conducted for all the different loads as well. 

The figures below shows the class separability for our data. The classes are healthy, 1 BRB, 2 BRB, 3 BRB, 4 BRB.

Each figure displays a different set of load. These include:

  • 5Nm
  • 10Nm
  • 20Nm
  • 30Nm
  • 40Nm

ICA plot for 5Nm load

ICA plot for 10Nm load

ICA plot for 20Nm load

ICA plot for 30Nm load

ICA plot for 40Nm load

What are Broken Rotor bar Faults?!

-

Induction machines are one of the crucial elements of many industrial processes nowadays (IM). These machines are prone to rotor, stator, or bearing failure due to diverse operating circumstances. All of these IM flaws have the potential to impair output, harm neighboring equipment, or, in the worst case, lead to the system’s complete failure[1]–[3]. Induction machines have been in use since the early 1800s. The operators or the equipment close to the working zones may be at danger from this motor’s strong starting torque and high operating speeds. Broken rotor bar defects are one of the frequent causes of motor failure, which may also be brought on by an unfavorable operating environment or artificial mis-operation during the manufacturing process. The rotor bar will first fracture locally, and the surrounding area will experience increased stress. As the defect worsens, the rotor bar entirely breaks, along with any adjacent bars, and finally the whole motor collapses. The early detec...

The Induction Machine We Used...

The bench of experiments is on the premises of the School of Engineering of São Carlos (EESC) of the University of São Paulo (USP), Brazil, more specifically in the Laboratory of Intelligent Automation of Processes and Systems (LAIPS) and Laboratory of Intelligent Control of Electrical Machines (LACIME). The machine parameters are given below:  220V / 380V 3.02A / 1.75A 4 poles 60Hz 4.1Nm Torque 1715 rpm Squirrel cage rotor (34 bars) To simulate the failure of broken bars in the squirrel cage rotor of the three-phase induction motor it was necessary to drill the rotor. Drilling was carried out by means of a bench drill mounted with a 6 mm diameter drill to ensure that the diameter of the hole exceeds the width of a rotor bar, with the tip centered at half the longitudinal length of the rotor. The link to the dataset is given below: https://ieee-dataport.org/open-access/experimental-database-detecting-and-diagnosing-rotor-broken-bar-three-phase-induction
