Design engineers now selecting pmbldc motors over conventional dc or induction motor drives for the following reasons : 1 ) the absence of brushes results in an essentially maintenance free operation and eliminates the undesirable effects of commutation such as sparks, brush - loss, radio - frequency interference, etc. 2 ) the low inertia of the rotor enhances the quality of the mechanical response of the motor, shortening the acceleration and deceleration time. 3 ) utilizing rare - earth permanent magnet materials with high coercive force results in substantially higher efficiency than their counterpart with brushes of the same size. 4 ) because of the absence of commutation segments, the stator construction is simple
現在的工程師們更為青睞永磁無刷直流電動機是因為以下幾點原因： （ 1 ）去除了電刷的永磁無刷直流電動機徹底地免除了維護而且消除了我們不希望的由於換向帶來的火花、電刷損耗以及無線電干擾等等； （ 2 ）低轉動慣量的轉子提高了電機機械響應的質量，從而縮短了電機加速和減速的時間； （ 3 ）高矯頑力稀土永磁材料的使用使得同樣尺寸的永磁無刷直流電動機比傳統的直流電動機效率高； （ 4 ）由於沒有機械換向部分定子的結構簡單了。The tbco amorphous films with and without cr underlayer had been successfully prepared onto glass substrate by magnetron sputtering method. the influence of the preparing conditions to the structure, coercivity and the perpendicular magnetic anisotropy ( pma ) of tbco films were investigated. and the origin of the pma in these films was studied
採用磁控濺射法在玻璃基片上成功地制備了帶有和不帶有金屬cr底層的tbco非晶垂直磁化膜，研究了制備工藝對tbco薄膜結構、矯頑力、垂直磁各向異性的影響，並對tbco非晶垂直磁化膜的磁各向異性來源進行了研究。
