absence of brush meaning in Chinese
无(碳)刷
无刷
Examples
- 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
现在的工程师们更为青睐永磁无刷直流电动机是因为以下几点原因： ( 1 )去除了电刷的永磁无刷直流电动机彻底地免除了维护而且消除了我们不希望的由于换向带来的火花、电刷损耗以及无线电干扰等等； ( 2 )低转动惯量的转子提高了电机机械响应的质量，从而缩短了电机加速和减速的时间； ( 3 )高矫顽力稀土永磁材料的使用使得同样尺寸的永磁无刷直流电动机比传统的直流电动机效率高； ( 4 )由于没有机械换向部分定子的结构简单了。 - 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
