This course will help you learn how to work with an AC motor, an electrical machine that converts electrical energy (or alternating current) into mechanical energy by electromagnetic induction. In this course, we will talk about single-phase and three-phase induction motors, how they work, methods of speed control, testing, protective measures, and more. At the beginning of this course, we will explain the construction of the most commonly used types of motors, namely the squirrel cage motor and the wound induction motor. Induction motors are further divided into "single-phase induction motor" and "three-phase induction motor" in this course. You will also learn how to reverse the direction of rotation of a three-phase motor.
We will discuss the single-phase and three-phase induction motors in detail. Under a single-phase induction motor, we can dwell deeper into its components, principle of operation, equivalent circuit, starting methods, and more. We will also study how to start a single-phase induction motor by capacitor start method. Similarly, under the three-phase induction motor. We will discuss its principle of operation, enclosure types, connection types, reversing operation, load-torque characteristics, and more. Want to learn more about the different methods of speed control explained in this course? If so, we will also look at the different types of AC motor starters, AC motor protection, tests of AC induction motors, etc. In addition to this, we will also explore how the bimetallic strip is activated as overload protection in motors?
You may also want to learn about the important role of "synchronous motors". This course will explain the synchronous motor operation, synchronous motor starting methods, load characteristics, power factor improvement, torque and V-curves, hunting, advantages and disadvantages, etc. We will also examine how to derive the torque equation of a synchronous motor? In addition, you will learn about other types of AC motors, namely the universal motor, the repulsion motor, and the AC series motor. By the end of this course, you will have taken a big step toward understanding one of the most important electrical machines powering the industrial world. So why wait, start your learning journey today.Start Course Now
