Formation of the excavator characteristics of a frequency-regulated asynchronous electric drive
Abstract
General requirements for excavator characteristics are presented. Equations are derived for excavator curves, based on frequency control by IR compensation and control with constant rated rotor frequency. The latter control principle is preferred with respect to space factor, total power losses and simplicity of accomplishing feedback.
