Description

In this course, you will learn how to use a DC generator an electrical machine that converts mechanical energy into electrical energy. DC Generators work on the principle of electromagnetic induction. The design, construction as well as parallel operation of DC generators are very simple and the problems regarding system protection with stability are very low. DC generators can be used in electrical devices that require DC power. In this course, you will learn about the classification of DC generators, which are mainly divided into two categories, namely separately excited and self-excited. Do you want to know more about the working principle of DC generators and the differences between AC generators and DC generators? In this course, all these points will be explained in great detail. You will also learn about EMF and load voltage as well as self-excited generators which have three subtypes namely series, shunt and compound generators and there are other subtypes as well. Each generator type DC has its own unique features, circuits and advantages.

Have you ever wondered how generators on constructed? In this course, we will take a closer look at the construction of DC generators. You may want to learn about the basic components of the generator DC and the armature winding and its types. We will also talk about the components of the armature core and the use of balancing windings and interpoles in a DC generator. We will also look at the critical resistance for the shunt generator field and the concept of critical speed for DC generators. You will be able to understand the various characteristics of DC generators namely magnetization, open circuit characteristics, internal characteristics etc. You will learn what magnetization properties are and how they explain the relationship between the no-load emf generated and the field current at a constant speed. Next, you will study the internal properties that explain the relationship between the generated voltage and the load current. In this course, you will learn how the external or load characteristics show the change in terminal voltage with load current at a fixed speed.

Do you want to understand voltage build up in generators? This course will explain the concepts of voltage buildup in a separately excited generator DC, the conditions that must be met for voltage buildup, and the methods of voltage control. By the end of this course, you will know more about DC generators and will have taken a big step toward understanding one of the most important electrical machines powering the industrial world. This course is ideal for electrical or mechanical engineering students who want to expand their knowledge in this field or working engineers who want to refresh their knowledge.
