1.除去...的磁性,给...退磁
1.to remove the magnetic properties from something
1.Due to the small size and difficulty of heat dissipation, the PM rotor is easier to be overheated and irreversible demagnetized.
同时由于高速永磁电机体积小散热困难,受电枢反应去磁和转子过热影响,容易产生不可逆失磁。
2.Ring should be demagnetized. Edge should be without burr.
环体必须消磁,棱边去毛刺
3.measuring method for demagnetized state permeability of microwave ferrite materials
