RT-2系列電動(dòng)旋轉(zhuǎn)臺(tái)的特點(diǎn)是緊湊和低剖面尺寸。
RT-2的厚度只有38毫米多一點(diǎn)，非常薄。該設(shè)計(jì)利用推力軸承系統(tǒng)來(lái)移動(dòng)工作臺(tái)。這種設(shè)計(jì)方法具有出色的穩(wěn)定性和低成本。RT-2采用蝸輪傳動(dòng)，可提供80:1和40:1的傳動(dòng)比。40:1的傳動(dòng)比將提供比80:1傳動(dòng)比更高的輸出速度。蝸輪被預(yù)加載以最小化齒輪系中的齒隙。這個(gè)小旋轉(zhuǎn)舞臺(tái)標(biāo)配NEMA 17步進(jìn)電機(jī)和可選的4000CPR旋轉(zhuǎn)編碼器。
