synchronous speed

基本解释

The efficiency of PLC control is increased at high speeds up to 95% of the synchronous speed.
PLC控制傚率在同步速度達到95%時提高不少。
Because the AC asynchronous motor' synchronous speed is determined by the frequency, we can control the AC asynchronous motor' speed by changing the supply power's frequency.
交流變頻調速系統是利用異步交流電動機的同步轉速隨頻率變化的特性，通過改變電機的供電頻率而進行調速。
The coupled dc motor can be adjusted so that the speed of the system is higher than the synchronous speed and the system rotates in the same direction as the stator rotating field.
所連接的直流電動機可以這樣調整使得其轉速高於同步轉速且鏇轉方曏與定子鏇轉磁場的方曏一致。

Metro networks have phone gear like digital cross-connects, which manage high-and low-speed traffic, and synchronous optical network (Sonet) systems, which come from fiber-optic phone networks.
FORBES: The God Box
The top-of-the-line Sanshara drives employ synchronous NAND technology and deliver the best speed and performance available in flash-based storage.
ENGADGET: Modbook Pro to launch with SSD storage, up for pre-order October 3rd
These boxes took in low-speed, asynchronous data from the field and packed it into high-speed (9600 bits per second, it seems quaint now) synchronous trunks.
