直流電機換向火花的自動分級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。It throughly solved some long time complicated questions such as high service rate in dc motor, large quantities of maintaining contact type drive controller, high energy consumption of dc locomotive
徹底解決了直流電機維修率高、換向火花及接觸組火花大、觸頭式司控器維修量大、直流電機車能耗高等老大難問題。The permanent magnet brushless dc motor is a dc motor using electronic commutation in place of mechanical commutation in fact, so it has excellent characteristics of dc motors, for example good start and timing performance. it simplifies the motor ' s structure and overcomes the friction disadvantages of ordinary dc motor because it does n ' t use mechanical commutation. it is extensively used in aviations, robots, digital machine tool and so on
永磁無刷直流電動機實際上是以電子換向代替機械換向的直流電動機，因而保持了直流電動機的優良特性，具有較好的起動和調速性能，又因它無需機械換向器使電機的結構簡單，可以從根本上克服一般有刷直流電動機易於產生換向火花的弊病，在航天、機器人、數控機床等許多工業領域已得到廣泛應用。The permanent magnet brushless dc motor is a dc motor using electronic communication in place of mechanical communication in fact, so it has excellent characteristic of dc motors, for example good start and timing performance. it simplifies the motor ' s structure and overcomes the friction disadvantages of ordinary dc motor because it does n ' t use mechanical communication. it is extensively used in aviations, robots, digital machine tool and so on
永磁無刷直流電動機實際上是以電子換向代替機械換向的直流電動機，因而保持了直流電動機的優良特性，具有較好的起動和調速性能，又因它無需機械換向器使電機的結構簡單，可以從根本上克服一般有刷直流電動機易於產生換向火花的弊病，在航天、機器人、數控機床等許多工業領域已得到廣泛應用。However, the traditional dc motor uses brush so as to switch the phases, so there are relative mechanical frictions. then it comes out many fatal failing, such as yawp, spark, wireless disturb, etc. what " s more, its making cost is high, its maintain is also difficult, therefore its application is greatly limited
直流電動機具有運行效率高和調速性能好等諸多優點，但傳統的直流電動機均採用電刷，以機械方法換向，因而存在相對的機械摩擦，由此帶來了噪聲、火花、無線電干擾以及壽命短等致命弱點，再加上製造成本高及維修困難等缺點，從而大大地限制了它的應用范圍。This magic is in keeping with to perform at the satge or the party, the magician controls a light ball arbitrarily, matching with various hua shi4 s technique and music result to attain super and strong magic result, if think " solo " in the dancing party to be also groovy a recruit. sees a magician stretch hand toward once the air grasp, a little very red light of fire has already been grasp in hand medium ; after rowing a circle in the sky pass the light of fire another again hand, after namely two hands mutual fast commutation light of fire, if can match with beautiful of body language, perform will very good see. the video frequency plays to show
這個魔術適合在舞臺或宴會上表演，魔術師將一個光球隨心所欲地控制，配合各種的花式技巧及音樂效果達到超強的魔術效果，若是想在舞會中" solo "也是很帥的一招。只見魔術師伸手向空中一抓，一點紅紅的火光已被抓在手中在空中劃個圈圈后再將火光傳給另一隻手，之後即兩只手互相快速的交換火光，若能配合優美的肢體語言，表演將會非常的好看。視頻演示：Sparking on commutator ' s carbon brushes is a common phenomenon in operation of the turbo - generator set, the causes resulting in sparking have been analysed, the experiences in aspects of operation, maintenance, and repair being summarized, and corresponding preventive measures beng put forward
