Detection of stator-based faults in Induction Machines (IMs) can be carried out numerous ways. In particular, the shorted turns stator windings IM are among most common industry. As a matter fact, IMs come with pre-installed current sensors for purpose control and protection. At this aim, using only fault detection has become recent trend nowadays as it is much cheaper than installing additiona...

Three phase induction machines for traction applications in electric and hybrid electric vehicles can be used with a fixed gear due to the wide speed range enabled by field weakening. Although the induction machine is know as an extremely reliable and robust device, machine faults may occur. Machine faults which do not become detected may cause complete failure of the vehicle. Therefore, early ...

Stator grounding is the most common fault of a large generator. If accurate coil can be located quickly and effectively, maintenance progress generator greatly sped up, put back into use as soon possible. For this purpose, stator location method for steam proposed, which takes distribution winding potential account. Firstly, characteristics influence are analyzed when single-phase ground occurs...

A reliable and accurate diagnosis of inter-turn short circuit faults is a challenging problem in the area of fault diagnosis of electrical machines. The purpose of this challenge is to be more efficient in fault detection and to provide a reliable method with low-cost sensors and simple numerical algorithms which not only detect the occurrence of the fault, but also locate its position in the w...

Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

The aim of this research was to discover the best indicators of induction motor faults, as well as suitable techniques for monitoring the condition of induction motors. Numerical magnetic field analysis was used with the objective of generating reliable virtual data to be analysed with modern signal processing and soft-computing techniques. In the first part of the research, a fuzzy system, bas...
