Welcome to the course of 0713-213: Energy Conversion I. This course is very important as it deals with two important machines -one is transformers and another is Induction Motors.  Motors and transformers are the key driving force for industrial and residential appliances. We can’t even imagine any countries power system without transformers. In industry all types of linear or rotational force, movement, torque etc. are applied by motors. Industries are getting automated day by day, hence the use of motors are increasing with the same pace. The power supply to any medium or large scale industry comes through transformer as the utilities prefer to supply at higher grid voltage. Maximum portion of power that is consumed in any industry is by motors. So the efficiency is a great issue for an industry owner to think about. The efficiency of the major consumer, the motor must be of as high as possible. The efficiency of the transformer, through which all the power is consumed, must also be near 100 percent. So every personnel related to the decision-making in industry must have the knowledge regarding the energy efficiency issue for motors and transformers.
This course examines the basic theory, characteristics, construction, operation and application of electrical machines which find widespread applications in power transmission and distribution systems and various industries. It includes the study of single phase transformer, three-phase transformer, poly phase induction motors and single phase induction motor. A detailed description and analysis of these machines is the main focus point of this course.
