ams OSRAM 最常用的磁編碼器系列產(chǎn)品有 AS56xx, AS5x47 和 AS5x48系列,今天我們重點(diǎn)梳理AS5x47系列的產(chǎn)品。廢話不多說,直入正題:
先把各型號(hào)的主要規(guī)格參數(shù)進(jìn)行表格整理

從上圖中不難看出:
- 所有產(chǎn)品均支持DAEC(動(dòng)態(tài)角度誤差補(bǔ)償),此技術(shù)可讓電機(jī)在高速旋轉(zhuǎn)時(shí)大大降低系統(tǒng)延遲;
- AS5047系列-40 to 125的工作溫度 屬于工規(guī)產(chǎn)品,AS5147/AS5247系列-40 to 150的工作溫度屬于車規(guī)產(chǎn)品;
- AS5047U ABI可達(dá)到14bit, 轉(zhuǎn)速28000轉(zhuǎn)/分鐘,是AS5047系列中最高的,且支持DFS(動(dòng)態(tài)過濾系統(tǒng)),綜合性價(jià)比最高;(??優(yōu)惠訂貨,具體可聯(lián)系我司)
- AS5047P/AS5047U 為 Pin to Pin 產(chǎn)品。
