Abstract:

This study aims to perform mathematical modeling of asynchronous motor and simulation of the rotor flux-oriented vector control method on a user-friendly platform for multi-physical models. Asynchronous motor is a good choice for the industry due to its low cost, high efficiency, robustness, high reliability, ability to work in bad environmental conditions, easy recycling, good dynamic performance, high maximum speed, and high range of field weakening. Although the scalar control method is sufficient in speed control applications by keeping the stator voltage/frequency ratio constant in asynchronous motors, in cases where the continuity of torque control is important, the scalar control method is not sufficient. With the scalar control method, a large range of speed control could be made at the nominal torque of the induction motor. However, the scalar control method was not sufficient in applications where continuous speed and torque control were required. Therefore, the vector control method is preferred. Besides, the obtained model is created as a PhiSim library, a product of Sherpa Engineering. This library was created using the bond-graph theory.  The outputs from this study will serve the automotive industry. This simulation tool will be beneficial in investment decision-making processes and research.
