The paper presents description of bearing, stator and rotor fault diagnostic methods of a
single-phase induction motor. The presented methods use acoustic signals. Five states of …

The article describes acoustic based fault diagnosis techniques of a three-phase induction
motor. Four real states of the three-phase induction motor were analysed: healthy three …

An early diagnosis of faults prevents financial loss and downtimes in the industry. In this
paper the authors presented the early fault diagnostic technique of stator faults of the single …

Single-phase induction motors are used in the industry commonly. Induction motors are not
expensive, so it is a reason to use them. Diagnostics of faults is very important. It prevents …

Aiming to solve the problem of noise generated by running gearbox, a computing method
was proposed for predicting the noise of a gearbox from steady dynamic response to the …

Diagnosis of electrical direct current motors is essential for industrial plants. The emphasis is
put on the development of diagnostic methods of solutions for capturing, processing and …

As a key component in power transfer, positive displacement machines often represent the
major source of noise in hydraulic systems. Thus, investigation into the sources of noise and …

This paper presents an experimental and numerical modal analysis for an external gear
pump considering its mounting on a test rig in a laboratory setting. Most of the previous …

Low noise fluid power units become a rapidly increasing demand in modern industry. This
paper describes the generation of vibrations and noise in fluid power units, which in many …

Synchronous hydraulic motors are used in high load conditions. Therefore, the failure of
such motors must be promptly detected to avoid severe accidents and economic loss. The …
