Stator winding fault diagnosis in dc motors during manufacturing using electromagnetic and thermal monitoring
نویسنده
چکیده
Abstract: Quality assessment during dc motor manufacturing should be accomplished by quality controls in order to detect the different fault conditions associated to the components included in the machine. However, some defects can be produced by the automatic manufacturing process during the assembly of the individual components. Among others, inter-turns short-circuit, turn to earth short-circuit and open-winding can result from the rotor insertion inside the stator. The main problem with these kind of faults is that the motor can operate but there is a high probability of motor breakdown in the near future.

Magnetic Saturation Impacts on Fault Analysis of Squirrel-cage Six Phases Induction Motors using Winding Function Approach
Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carri...
متن کاملImprovement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution
Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...

متن کاملA Fault Severity Index for Stator Winding Faults Detection in Vector Controlled PM Synchronous Motor
Stator turn faults in permanent magnet synchronous motors (PMSMs) are more dangerous than those in induction motors (IMs) because of the presence of spinning rotor magnets that can be turned off at will. Condition monitoring and fault detection and diagnosis of the PMSM have been receiving a growing amount of attention among scientists and engineers in the past few years. The aim of this study ...
