WebMulti-Mass Torsional Shaft Interface (Obsolete) Description. Input Parameters Description. This component simulates the dynamics of up to 26 masses connected to a single rotating shaft. One mass is normally used to represent the generator, and the electrical torque Te is applied to it. One mass may be used to represent an exciter. Websynchronous shaft generator is far from an optimal solution, as it has relatively low efficiency due to its low-speed operation. In traditional high-speed power generation, synchronous generators can achieve efficiencies up to 98–99%. In low-speed shaft generator applications, however, their efficiencies are in the range of only 93%.
