Demagnetization Analysis and Optimization of Bonded Nd-Fe-B Magnet Rings in Brushless DC Motors

Demagnetization Analysis and Optimization of Bonded Nd-Fe-B Magnet Rings in Brushless DC Motors

Bonded Nd-Fe-B magnets have greater freedom of shape than sintered Nd-Fe-B magnets. The ring structure is one of the typical structures of bonded Nd-Fe-B materials. In this paper, we analyzed the generation and spread of demagnetization fault (DMF) and changes in motor performance. Meanwhile, a BLDC...
