This paper presents an overview to main problems that may occur in load sharing of three-phase squirrel cage induction motors in tandem operation including mathematical transformations and dynamic model. In the study, two simulations for two individual problematic situations are performed and results are presented. Data for motors having “the same number of poles” and “different number of poles” are used for simulation. Dynamic behaviours for both cases are investigated and it is shown that one of the motors having higher rated speed has the risk of overloading when motors have same number of poles and the lower rated speed motor operates as generator when the motors have different number of poles as expected at the beginning of the study. An important amount of information is obtained from the study to protect test equipment and motors during the practical stage of the project.
