A hybrid finite-element–boundary element method is adopted for the analysis of linear induction machines (LIM) in Cartesian coordinates. A mathematical boundary is defined arbitrarily in free space to enclose the system. Finite-element formulation is applied for the interior region and boundary integral formulation is applied on the boundary using the response function excited by a transverse line...
In the last years, heavy-duty gas turbine has been increasingly used as high efficiency systems for heat and power generation. The typical size of these powerplants mainly consist compressor, turbine and combustor. And the rotor disc assembly structure is different from the single whole rotor structure. Several computer codes have been developed to analyse the strength of the rotor. In the present...
Recent research has seen an emergence of permanent magnet synchronous machines (PMSM) as strong contenders for applications requiring low torque pulsations and larger torque per (RMS) amp for the same volume of the machine. They are also highly in demand for applications requiring high fault tolerance. Owing to the advent of modern power electronics and advanced control schemes, little effort has...
