What are the Losses in DC Machine? | Eddy Current Loss & Hysteresis Loss | Efficiency of DC Machines | DC Machines Losses and Efficiency Hello Everyone, I am Dr. Saurabh Mani Tripathi and this is a short Lecture (Part-K) on the topic "Direct Current Machines: Losses and Efficiency". After completion of this short lecture, the viewers may be able to understand the reasons behind occurrence of various losses namely Core losses (including Hysteresis and Eddy Current losses), Copper losses, Mechanical losses and Stray load losses in a practical DC machine. The efficiency of the DC machine has also been introduced briefly. This short lecture is useful for the U.G. students, in particular, who are studying the electrical engineering / electrical machines course(s). I hope you will find this lecture useful. After watching this video lecture, the learner would be able to answer the following: 1. What are various losses in DC machines? 2. What is hysteresis loss in DC machines? 3. How hysteresis loss occurs in the armature core of a DC machine? 4. What is eddy current loss in DC machines? 5. How big is the eddy current loss? 6. How to reduce the eddy current loss? 7. Why armature cores are made of thin lamination? 8. What are mechanical losses in DC machines? 9. What are stray losses in DC machines? 10. What are copper losses? 11. The formula to calculate eddy current loss? 12. The formula to calculate hysteresis loss? 13. What is efficiency of DC machine? 14. Why the efficiency is less than 100 percent?
