AI3281-A-V001輸入卡件，TRICONEX使用產(chǎn)品
步進(jìn)電機(jī)一般不具有過載能力。交流伺服電機(jī)具有較強(qiáng)的過載能力。以M2交流伺服系統(tǒng)為例，它具有速度過載和轉(zhuǎn)矩過載能力。其最大轉(zhuǎn)矩為額定轉(zhuǎn)矩的二到三倍，可用于克服慣性負(fù)載在啟動(dòng)瞬間的慣性力矩。步進(jìn)電機(jī)因?yàn)闆]有這種過載能力，在選型時(shí)為了克服這種慣性力矩，往往需要選取較大轉(zhuǎn)矩的電機(jī)，而機(jī)器在正常工作期間又不需要那么大的轉(zhuǎn)矩，便出現(xiàn)了力矩浪費(fèi)的現(xiàn)象。運(yùn)行性能不同
AI3281-A-V001輸入卡件步進(jìn)電機(jī)的控制為開環(huán)控制，啟動(dòng)頻率過高或負(fù)載過大易出現(xiàn)失步或堵轉(zhuǎn)的現(xiàn)象，停止時(shí)轉(zhuǎn)速過高易出現(xiàn)過沖的現(xiàn)象，所以為保證其控制精度，應(yīng)處理好升、降速問題。交流伺服驅(qū)動(dòng)系統(tǒng)為閉環(huán)控制，驅(qū)動(dòng)器可直接對(duì)電機(jī)編碼器反饋信號(hào)進(jìn)行采樣，內(nèi)部構(gòu)成位置環(huán)和速度環(huán)，一般不會(huì)出現(xiàn)步進(jìn)電機(jī)的失步或過沖的現(xiàn)象，控制性能更為可靠。
六、速度響應(yīng)性能不同
步進(jìn)電機(jī)從靜止加速到工作轉(zhuǎn)速（一般為每分鐘幾百轉(zhuǎn)）需要200～400毫秒。交流伺服系統(tǒng)的加速性能較好，以鳴志400W交流伺服電機(jī)為例，從靜止加速到其額定轉(zhuǎn)速3000RPM僅需幾毫秒，可用于要求快速啟停的控制場(chǎng)合。
綜上所述，交流伺服系統(tǒng)在許多性能方面都優(yōu)于步進(jìn)電機(jī)。但在一些要求不高的場(chǎng)合也經(jīng)常用步進(jìn)電機(jī)來做執(zhí)行電動(dòng)機(jī)。所以，在控制系統(tǒng)的設(shè)計(jì)過程中要綜合考慮控制要求、成本等多方面的因素，選用適當(dāng)?shù)目刂齐姍C(jī)。 微芯片、OLED、LCD、植入物和半導(dǎo)體的生產(chǎn)以及制藥業(yè)，對(duì)生產(chǎn)環(huán)境的無塵等級(jí)要求非常高。每一種類型的污染都會(huì)對(duì)產(chǎn)品造成直接影響，給制造商帶來巨大損失。同時(shí)，制造商對(duì)機(jī)器元件和供能系統(tǒng)也提出了特別高的無塵要求。為此，igus在四年前推出了易于拆裝的全封閉型波紋管e-skin系列。它是獲得德國(guó)弗勞恩霍夫（Fraunhofer）應(yīng)用研究協(xié)會(huì)認(rèn)證的ISO 1級(jí)產(chǎn)品，并在2018年榮獲該協(xié)會(huì)的“Clean! 2018”潔凈技術(shù)獎(jiǎng)二等獎(jiǎng)。 其獲獎(jiǎng)理由是：由耐磨工程塑料制成的e-skin系列，擁有模塊化的結(jié)構(gòu)，并可快速布線。為了使e-skin系列適用于更狹小的安裝空間，igus采用新的柔性材料打造出了柔性型e-skin soft系列，它可以在架空長(zhǎng)度較短的狹小安裝空間中使用。 針對(duì)扁平安裝空間，igus也推出了一種帶內(nèi)腔設(shè)計(jì)的新解決方案——扁平型e-skin flat系列。兩款新拖鏈在運(yùn)行噪聲測(cè)試中都表現(xiàn)出色：柔性型e-skin soft系列的噪音值為32.4dBA，扁平型e-skin flat系列的噪音值為29dBA。 這表明，適用于無塵室的兩款新拖鏈相較于市場(chǎng)上的同類解決方案要更加安靜。
e-skin soft：模塊化，可快速填充
component, only aging without the limit of use times. The number of switches per minute of the relay is also limited, while the transistor does not. Transistors also have large currents, such as 5A or more It is the output of transistor. When there is a rear relay, pay special attention to the polarity of relay coil (generally, the coil is connected with protective diode or indicator light), otherwise the transistor will be burned out). Nowadays, industrial control products have developed to a stage of pursuing personalization and differentiation. The traditional PLC products have been unable to meet the more differentiated market demand. In order to meet this demand, there is a programmable control board. Programmable control board is a PLC that builds the PLC system software in the controller, customizes the hardware according to the user's control needs, and solves the object control problem by the application of PLC.
The example of the product proves that, based on the principle of tailorable software and hardware, the developed products can well meet the personalized needs of users, and various models can be customized according to the needs of users, which saves the hardware cost, shortens the R & D cycle, and obtains many powerful functions.
With the development of economy, the water supply capacity of most cities in China has been improved by leaps and bounds. Even at the peak of water consumption, the water supply capacity is still very rich, which lays the foundation for non negative pressure water supply equipment.
