Especially, detailed explanation will be made for variable speed control of the rotating machines and re-generation method. Recent trends for the developments of the electric machineries such as ones for the electric vehicle and the wind turbine are also to be outlined. | |||
| Course Goals | Understand fundamentals of designs, kinetic characteristics, coordinate transform as well as concept of variable speed control and drive-control method of rotating machineries. Also, understand basic concepts on recent trends of the developments. | |||
| Schedule and Contents |
Concept of output power and fundamental aspects of design in electric machineries,2-3times,Discuss the relationship among output power, rotating speed, pole number, electric loading and magnetic loading in electric machineries. Also, concept of temporal rating and that of object oriented design are also to be explained. load characteristics and kinetic characteristics,1-2times,Discuss the load characteristics, kinetic characteristics, etc. of the rotating machineries are explained. Examples of visulalized simulation results may also be shown for the aid of easier understanding. Principle of variable speed control of rotating machineries,6-8times,Based upon concrete examples, necessity for the variable speed control of the rotating machineries is discussed. And then, fundamental equations of respective rotating machines, method of coordinate transform for the expression of dynamic characteristics are explained. Further, basic concept and fundamental principle of the variable speed control is described. Power conversion for drive of rotating machines,1-2times,Power conversion method for the realization of variable speed control is explained. Permanent magnet rotating machines,1time,Permanent magnet rorating machine, which is one of the most major motors, is explained from the point of view of its rotating principle as well as characteristics. Trends of new electric machineries,1time,Trends of developments of new rotating machineries, e.g., electric (hybrid) automobile, linear motor, wind turbine, etc., are outlined. Also, concept and meaning of re-generation is explained. Summary,1time,The classes are summarized. This is the feedback to students according to their score. |
