Several torsional issues have been reported in drive train applications such as oil and gas or mining, where the drive rated power exceeds the megawatt range. This paper analytically explains why mechanical engineers worry about this phenomenon in such applications. Simple and comprehensive relationships are established, and electrical and mechanical(More)
This paper presents new, simple, and linear mathematical relationships to predict pulsating torque frequencies in industrial multi-megawatt pulse width-modulated (PWM) drives. The proposed relationships provide direct definition of possible drive operating points where the torsional resonance modes of the mechanical shaft assembly might be excited. The(More)
