The contact interfaces for the rod-fastened rotor of a heavy-duty gas turbine rotor were analyzed and classified into three kinds. In order to predict the effects of contact interfaces on the rotor dynamic characteristics of the heavy-duty gas turbine generator set, the torsional characteristics of the contact segments were studied firstly. The piecewise bilinear torsional deformation model for the...
An analytical model is proposed using the d/q-axis model to estimate the maximum output power of the high speed permanent magnet synchronous generator (PMSG) and corresponding current, power-angle, etc. An experimental phenomenon that a 100kW 45000rpm PMSG unable to generate rated power is analysed using the analytical model. Then the rotor structure is improved according to the analytical results...
The eddy currents induced in a thrust bearing result not only in a power loss of the system but also in phase lag and a decrease in magnitude of the magnetic force. Therefore, an accurate model including eddy-current effects would be highly beneficial at the design stage. We present a linear model including eddy-current effects for a typical active magnetic thrust bearing (AMTB). We define and calculate...
