Electromagnetic Field Analysis of Switched Reluctance Motor under Different Conditions using Finite Element Method

This paper presents the effects of air gap faults on flux, flux density, magnetic field intensity, and surface force density distribution in switched reluctance motor in both healthy and 44% eccentricity faulty conditions. Investigation of numerical electromagnetic fields has become the foremost job for the design and development of electromagnetic devices.The electromagnetic field analysis useful for perfect design and estimation of working of a motor. The most observed faults in rotating machines are the eccentricity faults which may lead to producing the unbalanced distribution of a magnetic field and also causes the structural and thermal problems in machines. This paper describes a two-dimensional finite-element analysis of an 8/6 switched reluctance motor with different types of eccentricities.
