This paper presents a stator inter-turn fault detection approach for the inverter-fed induction motor (IM) based on the Teager-Kaiser energy operation (TKEO). The zero sequence voltage under the excitation of the inverter switching harmonics is analyzed, and the characteristic frequencies of the inter-turn fault in the inverter common-mode voltage (CMV) is derived. In this way, the monitoring sensitivity...
This paper presents a method of detecting rotor faults in induction motors using the fast orthogonal search (FOS). Proper online condition monitoring of induction machines is very important to ensure safe operation, timely maintenance, and efficiency. It has been shown that when a fault occurs in the rotor, it will exhibit itself as a series of sidebands around the fundamental frequency in the stator...
In a companion paper (Part I) the bar breakages for a 1.13 MW induction motor used in high speed railway traction drives were studied, by simulating the whole system (converter + motor) and by analyzing frequencies and amplitudes of current sidebands, for various loads (both active and inertial) and with increasing fault severity. It was recognized that faults can be characterized by (1-2s)f sideband,...
