Mechatronics II

DC Motor

Welcome to the Home page for Mechatronics II

In this course we will discuss 3Ø (three-phase) devices ( i.e 3Ø Transformers and 3Ø Induction Motors ). At the end of this course the student is expected to be familiar with the Principles of 3Ø devices and their application in real life.

You are advised to read carefully through given material and attempt all quiz/questionnaires in this course and don't forget to follow necessary safety code that will be outlined in this course. We hope you will enjoy this major course in Electrical Engineering.

Course Outcomes
