ABSTRACT
Torsional vibrations must be considered in design of all high-power drive trains including an induction motor. Magnetic field in the air gap of induction motor generates additional stiffness and damping between the rotor and stator. The inclusion of these magnetic effects is limited by the availability of portable motor models. The aim of this paper is to introduce a portable digital twin of induction motor for electrical drive trains. This digital twin is based on the linearization of common equivalent-circuit models of induction motors. The calculation results for a motor-driven reciprocating compressor demonstrate the accuracy and advantages of developed digital twin.
