Advanced Electromechanical Systems 1 ELE 847 Lab 3 Three-phase Induction Motor Dynamic Performance Objectives - To build a Simulink model of a three phase induction motor; and - To investigate induction motor dynamic performance. Part A: Induction Motor Dynamic Model The block diagram of a three-phase induction motor fed by a three-phase power supply is shown in Fig. 1. The specifications and motor parameters are as follows: i) AC Supply A three-phase power supply with phase voltage of 127V (rms) and frequency of 60Hz.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
