In order to improve energy efficiency and compact structure, the dual-rotor structure, with low-
pressure rotor and high-pressure rotor, has been widely used in aero-engines. In severe …

At present, the fourth industrial revolution is pushing factories toward an intelligent,
interconnected grid of machinery, communication systems, and computational resources …

With the widespread application of the Internet of Things (IoT) technology, smart fault
detection and condition monitoring are urgently required in mechanical systems. The …

This paper deals with a new diagnosis method for detecting bearing faults (BFs) based on
frequency response analysis. For non-rigid multi-mass systems with dominant mechanical …

After unbalance, coupling misalignment is the most common fault present in rotating
machines. However, limited research has been carried out on coupling misalignment and its …

Condition monitoring of bearings is an open issue. The use of the stator current to monitor
induction motors has been validated as a very advantageous and practical way to detect …

Misalignment is one of the most common mechanical faults in electrical rotating machinery, it
can lead to partial or total breakdown of a motor in the long run may. This paper investigates …

In this paper, faults in induction motors were diagnosed using the Common Vector Approach
(CVA). In order to verify the performance of CVA, a database including stator current signals …

For an induction machine, we suggest a theoretical development of the mechanical
unbalance effect on the analytical expressions of radial vibration and stator current. Related …

In the present article questions of the validity and feasibility of establishing a system of
diagnosis and assessment of the residual life of the electromechanical equipment as the …
