Space Harmonic Analysis of Magnetic Fields in a Compensated Pulsed Alternator or an Active Rotary Flux Compressor
MetadataShow full item record
This paper discusses the space harmonic Fourier analysis of magnetic fields for a compensated pulsed alternator (compulsator) or an active rotary flux compressor (ARFC), which has been applied for two particular sets of boundary conditions appropriate for these machines to calculate magnetic field distributions, inductances, and how those inductances vary with rotor position. The results of the analytic model are compared with experimental results. This paper also shows the results of the extensive parametric studies using the inductances calculated from space harmonic distribution (SHD) code to explore design alternatives to improve the performance of these machines.
