Abstract
  Static eccentricity (SE) is an intrinsic fault existing in both faulty and newly made resolvers. The late diagnosis of SE causes severe damages to mechanical parts of resolver such as bearings, cores and even windings, in addition to wrong position estimation. However, so far fault diagnosis has not ...  Read More

Abstract
  In this paper no-load and full-load performance of Permanent Magnet Vernier Generators (PMVGs) is investigated in fully-aligned condition and under different types of mechanical faults. The studied mechanical faults are Static Eccentricity (SE), Dynamic Eccentricity (DE), Inclined Rotor (IR), and Run-out ...  Read More
