This paper presents the use of the induction motor current to identify and quantify common
faults within a two-stage reciprocating compressor based on bispectrum analysis. The …

Early assessment of machinery health condition is of paramount importance today. A sensor
network with sensors in multiple directions and locations is usually employed for monitoring …

The development of portable devices that make the reliable diagnosis of faults in electric
motors possible has become a challenge for many researchers and maintenance …

This paper investigates the performance of the conventional bispectrum (CB) method and its
new variant, the modulation signal bispectrum (MSB) method, in analysing the electrical …

This paper presents an advanced signal processing method applied to the diagnosis of rotor
asymmetries in asynchronous machines. The approach is based on the application of …

To accurately extract the fault characteristics of vibration signals of rotating machinery is of
great significance to the unit online monitoring and evaluation. However, because the …

Motor current signature analysis (MCSA) has been an effective method to monitor electrical
machines for many years, predominantly because of its low instrumentation cost, remote …

Broken rotor bar/end-ring is a common fault in squirrel cage induction motors and has been
thoroughly investigated in the case of AC grid supply. In this paper, this type of fault is …

A novel approach for rotor fault diagnosis during the start-up process is proposed. Rotor
faults create asymmetries that affect the phase currents in a subtle yet distinctive way. The …

Rotor electrical faults are common types of faults in squirrel cage induction motors and have
been investigated in detail in steady state condition for grid-connected induction motors. In …
