In the frequency-amplitude spectrum of a 2-Pole/4-Pole dual-winding induction motor operating at various times off electric company power, an in-factory motor generator (MG) set, a 6-step inverter-rectifier, variable speed power supply and a pulse-width-modulated (PWM)variable speed power supply...
My understanding of the meaning of generalized mass from an eigenvalue analysis is that it represents inverse damping, ie, the higher the generalized mass, the lower the damping at the calculated modal frequency. A supplier provided eigenvalue calculations for a 100+ node pump and motor giving...
