Harmonic Order Tracking Analysis: A Speed-Sensorless Method for Condition Monitoring of Wound Rotor Induction Generators

Sapena Bañó, Ángel; Riera Guasp, Martín; Puche Panadero, Rubén; Martínez Román, Javier Andrés; Pérez Cruz, Juan; Pineda Sánchez, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016-11)

[EN] This paper introduces a speed-sensorless method for detecting rotor asymmetries in wound rotor induction machines working under nonstationary conditions. The method is based on the time-frequency analysis of rotor ...
Reliable Detection of Induction Motor Rotor Faults Under the Rotor Axial Air Duct Influence

Yang, Chanseung; Kang, Tae-June; Hyun, Doosoo; Lee, Sang Bin; Antonino Daviu, José Alfonso; Pons Llinares, Joan (Institute of Electrical and Electronics Engineers (IEEE), 2014-08)

Axial cooling air ducts in the rotor of large induction motors are known to produce magnetic asymmetry and can cause steady-state current or vibration spectrum analysis based fault detection techniques to fail. If the ...
