Mechanical imbalance and eccentricity are usual faults in induction motors. These two faults can be identified by their effects in the stator current spectrum using motor current signature analysis. However, if the motor is supplied by electronic converters the identification of the fault is more complex, since additional harmonic components appear, caused by the converter. The main objective of the present work is to investigate the possibility of identifying these faults in a motor which is supplied by a power converter, specifically the slip energy recovery drive. To this purpose, the rotor current space vector modulus harmonic components are examined. The system is at first investigated through simulation in Matlab-Simulink. Thereafter, experimental tests are conducted. Characteristic results are presented and discussed.

Future digital audio delivery systems, especially for home-based multichannel applications, will greatly benefit from the evolution of all-digital wireless networked receivers integrating amplification, signal processing and direct digital emission. The paper will examine the limitations imposed by current technologies and methods in each of these contributing fields, i.e.: WLANs, amplification, signal processing for format adaptation and acoustics compensation and direct acoustic transduction of digital streams. It will be shown that current WLAN protocols lacking adequate quality guarantees cannot support the required high resolution multichannel audio traffic without appropriate post-processing for potential channel-induced error concealment. It will be also discussed why such systems may need to incorporate flexible bitstream conversion between PCM audio (the de-facto format after wireless reception), PWM (most appropriate for amplification) and DSD (most suitable for direct bitstream acoustic transduction). The current limitations imposed by the transducer elements will be also briefly examined. The alternative strategies for adaptation of such systems to the acoustic environment will be also analysed. The known limitations of the system-depended approach for acoustic compensation using inverse digital filtering will be illustrated and compared to novel, recent results following a signal-depended adaptation, using perceptually-based distortion maps and other relevant interaural cues.
