電刷火花
英文
brush spark-
Ac induction motor will govern speed stepless, no brush 、 no spark and long life
交流感應電機無極調速，無電刷、無火花、長壽命。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。Main purpose : it is widely used in steady speed mix, high speed disperse and sand will lab process. it adopt mouse cage motor, so no sparkle phenomena when working
主要用途:廣泛適用於穩速攪拌，高速分散，砂磨實驗過程。由於採用了籠式電機，運轉時不會產生火花。與有刷電機相比，無碳刷磨損的問題，噪聲小。We take some measures to prevent the emergence of disturbance when we design the hardware. for example, we increase the copper breadth according to the magnitude of the electric current. the rc circuit is used to absorb the spark generated by buttons and relays when they are putted at the same time, we use the redundancies instruction technology and the trap technology in software aspect avoiding the interference, which can assure the system work credibility
在硬體上，我們設計印刷電路板時採取一些措施如根據電流的大小，將相對應的銅線寬度加粗，利用rc電路加以吸收按鈕、繼電器等零部件操作時產生的火花等防止干擾的產生；在軟體上，我們採用了指令冗餘技術和軟體陷阱等抗干擾措施，以保證系統可靠工作。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

電火花加工產生的熔融工件切屑，藉助超聲波振動從工件上彈出，從工作間隙輸送/沖刷出去，而不會附著在電極上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。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
