Experimental Validation of Motor Current Signature Analysis for a 2HP Induction Motor

Abstract

The use of stator currents signal analysis for rotating electrical machines monitoring, particularly induction motors, has developed a growing interest, as the information contained in the spectrum of the current signal can indicate the presence of various types of both electrical and mechanical failures. In this work a test bed for induction motors 2 HP was implemented in order to validate the MCSA (Motor Current Signature Analysis) methodology, for the detection of: short circuit in the stator winding, broken rotor bars and eccentricity gap under different load conditions. Results show the dependency between the load level on the motor and the possibility to detect faults, and make possible to assess the feasibility of implementing MCSA methodology in of condition-based maintenance (CBM) schemes.
