    Performance analysis of axially laminated anisotropic synchronous reluctance motor

    In an effort to obtain better performance of SRM by obtaining a high ratio of direct (d) axis to quadrature (q) axis magnetizing inductances ( d q L L ) an axially laminated anisotropic (ALA) rotor was designed and fabricated. To construct an ALA rotor the axially laminated segments were constructed with multiple C.R.G.O laminations interleaved with milo paper insulation sheets. The thickness of C.R.G.O lamination and milo paper insulation sheet were of .2 and .25 mm respectively. The rotor has been designed for four poles configuration. The objective of this study was to design and fabricate axially laminated anisotropic synchronous reluctance motor for performance analysis. Parameters of SRM determined by A.C stand still test. The saturation effect was studied by synchronous running test. We analyzed the steady state and dynamic state behaviour of the SRM by developing a mathematical model. The presence of third and fifth harmonic at no-load and load condition was also determined. The results reveal that the steady state analysis performance on simulated of SRM as well as experimentally on test motor were in close agreement. The saturation effect was found negligible in motoring mode. The harmonic contents included third and fifth harmonics in very small percentage and increased slightly with loading.
