Magnetic Field Analysis for Health Monitoring of Induction Motor Using Search Coil

Induction motor undoubtedly has an important role in the industry on account of their benefits over other electrical motors. Consequently, there is a strong requirement for their consistent and reliable operation. If any defect and failures take place in the motor it could result in unnecessary downtimes and bring about great losses with regards to revenue and maintenance. Hence, early fault detection is considered essential for the safety of the motor. The research work presents a broad view of the fault indicators generally employed for finding defects in motors, with a special interest on electromagnetic flux monitoring, as the current study depends on the indications given by these parameters. In the present circumstances, the health or condition monitoring of the induction motor are progressively increasing on account of its prospective to lessen operating costs, improve the consistency of operation and enhance service to the customers. The faults executed in the motor's structures and their modeling processes are presented. A specification of the measurement system employed for the validations of the findings acquired from experimental setup and optimization are employed in the field of fault identification in electrical motors is as well to be found in this work. With increasing demands for consistency and effectiveness, the field of fault analysis in induction motors is receiving lots of importance. If the defects are not predicted in advance, it might bring about large revenue losses and also create threat to consistency and safety of operation. Though, many techniques have been recommended for fault detection and analysis, but the majority of the techniques demand a good deal of knowledge to implement them effectively. Simpler approaches are required to facilitate even unprofessional operators with minimal knowledge of the system to detect the defect condition and make appropriate decisions.
