Analysis using D-Q transformation of a drive system including load and two identical induction motors

Abstract

This paper contains a mathematical model of a system including two identical three-phase squirrel cage induction motors and a load driven by these motors. While modeling the drive system, to represent three phases as two phases, d-q transformation was used. Mathematical model of the system was obtained and then built in MATLAB Simulink. In the drive system which contains a load and two identical motors having their shafts connected to each other, the two identical motors drive the load at the same time. Dynamic behaviour of the motors and the load was analysed. Calculated individual torque of each motor and the load sharing was as expected. This study is the second step to check the first step of the analysis of load sharing between multiple motors which can be either identical or else.
