BISON GEAR減速電機(jī)
伺服電機(jī)可使控制速度，位置精度非常準(zhǔn)確，可以將電壓信號(hào)轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動(dòng)控制對(duì)象。伺服電機(jī)轉(zhuǎn)子轉(zhuǎn)速受輸入信號(hào)控制，并能快速反應(yīng)，在自動(dòng)控制系統(tǒng)中，用作執(zhí)行元件，且具有機(jī)電時(shí)間常數(shù)小、線性度高、始動(dòng)電壓等特性，可把所收到的電信號(hào)轉(zhuǎn)換成電動(dòng)機(jī)軸上的角位移或角速度輸出。分為直流和交流伺服電動(dòng)機(jī)兩大類，其主要特點(diǎn)是，當(dāng)信號(hào)電壓為零時(shí)無自轉(zhuǎn)現(xiàn)象，轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降

采用以恒壓頻比方式工作的通用變頻器來直接驅(qū)動(dòng)感應(yīng)電機(jī)在工業(yè)生產(chǎn)領(lǐng)域中應(yīng)用很廣泛。在不改變?cè)械暮銐侯l比變頻調(diào)速系統(tǒng)結(jié)構(gòu)的前提下，進(jìn)一步提高該系統(tǒng)的控制性能意義很大。該文根據(jù)恒壓頻比控制的特點(diǎn)，把通用變頻器和感應(yīng)電機(jī)看成一個(gè)整體——恒壓頻比變頻調(diào)速系統(tǒng)，給出了相應(yīng)的數(shù)學(xué)模型，并得出了適用于帶補(bǔ)償和不帶補(bǔ)償?shù)暮銐侯l比運(yùn)行方式的逆系統(tǒng)模型，進(jìn)一步構(gòu)造神經(jīng)網(wǎng)絡(luò)逆系統(tǒng)并與恒壓頻比變頻調(diào)速系統(tǒng)串聯(lián)復(fù)合成偽線性系統(tǒng)，再設(shè)計(jì)線性閉環(huán)調(diào)節(jié)器實(shí)現(xiàn)高性能控制。實(shí)驗(yàn)結(jié)果證明了采用神經(jīng)網(wǎng)絡(luò)逆控制方法可以使恒壓頻比變頻調(diào)速系統(tǒng)獲得優(yōu)良的運(yùn)行性能。

Bison Gear & Engineering Corp. designs and manufactures fractional horsepower electric motors, gearmotors and gear reducers used in industrial and commercial OEM applications worldwide. Bison's strong engineering tradition, based on Robusticity? principles, offers products with up to twice as much torque in the same package size as competitors.
