| Abstract: | The irreversible flux loss is an important performance index of sintered Nd-Fe-B magnets for permanent magnet motor.The accuracy of its measurement results directly affects the design of motor and the selection of magnetic performance.The irreversible flux loss of magnets under different test conditions is studied.The results show that the irreversible flux loss is mainly affected by tray properties(material/specification),magnet spacing and baking temperature.In order to obtain accurate measurement results of irreversible flux loss,these factors should be effectively controlled in the measurement process. |
| Keywords: | metrology sintered Nd-Fe-B irreversible flux loss open/closed circuit tray material/specification spacing baking temperature |
