2.伺服電機(jī)和其他電機(jī)(如步進(jìn)電機(jī))相比到底有什么優(yōu)點:
1、精度:實現(xiàn)了位置,速度和力矩的閉環(huán)控制;克服了步進(jìn)電機(jī)失步的問題;
2、轉(zhuǎn)速:高速性能好,一般額定轉(zhuǎn)速能達(dá)到2000~3000轉(zhuǎn);
3、適應(yīng)性:抗過載能力強(qiáng),能承受三倍于額定轉(zhuǎn)矩的負(fù)載,對有瞬間負(fù)載波動和要求快速起動的場合特別適用;
4、穩(wěn)定:低速運行平穩(wěn),低速運行時不會產(chǎn)生類似于步進(jìn)電機(jī)的步進(jìn)運行現(xiàn)象。適用于有高速響應(yīng)要求的場合;
5、及時性:電機(jī)加減速的動態(tài)相應(yīng)時間短,一般在幾十毫秒之內(nèi);
6、舒適性:發(fā)熱和噪音明顯降低。

3)試方向
對于一個閉環(huán)控制系統(tǒng),如果反饋信號的方向不正確,后果肯定是災(zāi)難性的。通過控制器打開伺服的使能信號。此時伺服電機(jī)應(yīng)該以一個較低的速度轉(zhuǎn)動,這就是所謂的“零漂”。一般控制器上都會有零漂的指令參數(shù)。使用這個指令或參數(shù),看電機(jī)的轉(zhuǎn)速和方向是否可以通過這個指令控制。如果不能控制,檢查模擬量接續(xù)及控制方式的參數(shù)設(shè)置。確認(rèn)給出正數(shù),電機(jī)正轉(zhuǎn),編碼器計數(shù)增加;給出負(fù)數(shù),電機(jī)反轉(zhuǎn),編碼器計數(shù)減小,如果電要帶有負(fù)載,行程有限,不要采用這種方式。測試不要給過大的電壓,建議在1V以下。如果方向不一致,可以修改控制器或電機(jī)上的參數(shù),使其一致。

一套模具一般允許氮化3~5次;復(fù)雜的高倍齒散熱器型材模不進(jìn)行氮化工序;對老產(chǎn)品的新模子、棒模、圓管??刹唤?jīng)試模直接進(jìn)行氮化處理;新產(chǎn)品及復(fù)雜型材模必須經(jīng)試模合格后才能進(jìn)行氮化處理;新模試模合格后,多擠壓1個鑄錠就應(yīng)卸機(jī)進(jìn)行氮化處理,避免將工作帶拉出溝槽;兩次氮化之間不可過量生產(chǎn),一般平模為6~1個錠,分流模為4~8個錠為宜,過多會將氮化層拉穿。使用后的模子拋光后,涂油人庫保管。
