Advantages And Disadvantages Of Electric Drive System

2.1 Variable Speed Drive System This chapter deals with the classification and basic operation of electric variable speed drive system and scope, merits and demerits of DC and AC drives. Then AC induction motor drive is selected for complete description. Here AC drive system is presented with its components like inverters, position sensors and current controller.
Figure 2.1: Classification of Electric Drive System Above fig. 2.1 shows the complete classification of Modern Electric Drive system. The rings in the above fig. 2.1 show the type of motor and type of converter chosen for doing thesis work. In every industry there are industrial processes of some form that require adjustment for normal operation or for optimum perf@ormance. Such adjustments are usually accomplished with a variable–speed drive (VSD) system. The VSD systems are an important part of automation. They help to optimize the process and to reduce inve&stment costs, energy consu*mption and energy cost. ... Show more content on Helpwriting.net ...This thesis focuses mainly on electrical drives. A typical electric VSD system consists of three basic components: the electr+ic motor, the power conv%erter and the control system, as illustrated in fig. 3.2. The electric motor is connected directly or indirectly (through gears) to th.e load. The power convert–er controls the po0wer flow from an AC supply (often via a supply transformer) to the motor by appropriate control of power semiconductor switches (part of the power
