PROJECT TITLE :
Characterization of Electrical Steels for High-Speed Induction Motors Applications: Going Beyond the Common Practices
The objective of the current work is to assess the impact of enhancements in normal characterization parameters of electrical steels, sometimes found in manufacturer catalogs (B50 and W10/four hundred), in the performance of high-speed electrical motors. The electrical steel manufacturer has to accommodate numerous process variables and long and expensive development times to come back up with new products. Hence, even small improvements within the B50 and W10/400 parameters are thought-about to be great achievements. So as to verify if such improvements really translate into real gains in electrical motors, a series of prototypes was constructed with newly developed electrical steels. The core losses of those prototypes were determined by the loss segregation method. Check results support the conclusion that the quality steel characterization parameters don't carry enough data for steel and motor makers to conclude on the performance of an electrical steel grade. An expanded datasheet for electrical steels is proposed and might be used in the steel development process as a brand new product assessment tool. The proposed datasheet carries helpful info for both steel manufacturer and electrical motor designer.
