伺服系統(tǒng)(伺服機(jī)構(gòu))是一種自動(dòng)控制系統(tǒng)，它使物體的位置、向、狀態(tài)和其他輸出受控星跟隨輸入目標(biāo)(或給定值)的任何變化。舵機(jī)主要靠脈沖到位置，基
本上可以這樣理解,伺服電機(jī)接收到一個(gè)脈沖，它就會(huì)旋轉(zhuǎn)相應(yīng)的一個(gè)脈沖的角度,從而達(dá)到位移,因?yàn)樗欧姍C(jī)本身具有脈沖的功能，所以伺服電機(jī)每旋轉(zhuǎn)一個(gè)角度,都會(huì)發(fā)出相應(yīng)的脈沖數(shù)，使伺服電機(jī)接受的脈沖回波。 或者閉環(huán),這樣系統(tǒng)就會(huì)知道向伺服電機(jī)發(fā)送了多少脈沖，又接收了多少脈沖，這樣就可以非常準(zhǔn)確地控制電機(jī)的旋轉(zhuǎn),從而實(shí)現(xiàn)精確的定位,可以達(dá)到0 001mm。直流伺服電機(jī)分為有刷電機(jī)和無(wú)刷電機(jī)。有刷電機(jī)成本低,結(jié)構(gòu)簡(jiǎn)單，啟動(dòng)轉(zhuǎn)矩大，調(diào)速范圍寬,控制方便,需要維護(hù)，但維護(hù)不方便(換碳刷)， 電磁干擾, 需要環(huán)境。因此，它可用于對(duì)成本敏感的一般工業(yè)和民用應(yīng)用。無(wú)刷電機(jī)體積小，量輕,輸出大,響應(yīng)快,速度快,慣量小，旋轉(zhuǎn)平穩(wěn),轉(zhuǎn)矩穩(wěn)定?？刂茝?fù)雜,易于實(shí)現(xiàn)智能化,子換向方式靈活,可以是方波換向或正弦波換向。電機(jī)免維護(hù),效率高，工作溫度低,電磁輻射小,壽命長(zhǎng),可在各種環(huán)境中使用。

A servo system (servomechanism) is an automatic control system that causes the position, direction, state, and other output controlled stars of an object to follow any change in the input target (or given value). The steering gear is mainly pulsed to position, Kee
This can be understood in this way, the servo motor receives a pulse, it will rotate the corresponding pulse Angle, so as to achieve displacement, because the servo motor itself has the function of pulse, so each rotation Angle of the servo motor will emit the corresponding pulse number, so that the servo motor accepts the pulse echo. Or close the loop, so that the system will know how many pulses are sent to the servo motor, and how many pulses are received, so that the rotation of the motor can be controlled very accurately, so as to achieve accurate positioning, which can reach 0 001mm. Dc servo motor is divided into brush motor and brushless motor. Brush motor has low cost, simple structure, large starting torque, wide speed regulation range, convenient control, need maintenance, but maintenance is not convenient (change carbon brush), electromagnetic interference, need environment. Therefore, it can be used in general industrial and civil applications where costs are sensitive. Brushless motor small size, light weight, large output, fast response, fast speed, small inertia, smooth rotation, stable torque. The control is complex, easy to realize intelligence, and the subcommutation mode is flexible, which can be square wave commutation or sine wave commutation. The motor is maintenance-free, high efficiency, low operating temperature, small electromagnetic radiation, long life, and can be used in a variety of environments.
