The Team has a wide experience in the application of techniques relying on the analysis of the current demanded by the motor.
The Team is expert in the application of two types of methodologies:
Classical current analysis method (MCSA): it relies on the analysis of steady-state current via the Fourier transform. The Team has a wide expertise in the application of this methodology; we rely not only on the classical harmonics typically employed by the available commercial devices (e.g. sideband harmonics), which may be non-conclusive or yield false indications, but also on higher order harmonics linked to the failure that are less affected by other non-fault related phenomena. This enables to reach a high reliability in the diagnostic.
Modern transient current analysis methods (ATCSA): the most common is based on the analysis of the starting current of the motor. Our advanced tools enable to analyse this signal and automatically track the patterns caused by the evolutions of possible fault components present in the signal. These methodologies have a very high reliability avoiding false indications of classical methods.
We have applied ATCSA in a wide number of industrial applications with excellent results avoiding large losses for the involved companies.

Our services include the measurement and analysis of current signals and, optionally, the analysis of stray flux signals. In this regard, we offer two different options:
OPTION 1: The user captures the signals and delivers them to us. We analyse them with our tools and we send back a complete full report with a detailed analysis of such signals.
We can provide assessment for signal acquisition and we explain the basic features of the captured signals. The process is easy and a simple oscilloscope is only required.
If you are interested in this option, you can send your signals to the following e-mail and we will provide feedback about sample results and cost of the service: joanda@die.upv.es
OPTION 2: We travel to the user facility or installation and we acquire the signals with our equipment. After analysing them, we deliver a complete and detailed report with the diagnostic results. If you are interested in requesting a budget for this service contact: joanda@die.upv.es
We analyse both steady-state (MCSA) and starting current signals (ATCSA). Our team can also analyse stray flux signals both during starting and at steady-state if the user wants too.
