Effects of external field orientation on permanent magnet demagnetization
IEEE Transactions on Industry Applications(2017)
摘要
This paper investigates how the orientation of the applied demagnetizing magnetomotive force (MMF) affects the demagnetization behavior of Nd-Fe-B magnets that are widely used for permanent-magnet synchronous machines (PMSMs). This paper designs and builds a customized test fixture that can produce a magnetic field with varying orientation and intensity to demagnetize magnet samples. A computer-co...
