Miki Pulley Việt Nam : SHM-25 + SHD2-08 - Linear shaft drives

These new cylindrical linear motor systems were designed to enable driving with the simplest possible system. They detect position using flux generated by the shaft, so they can operate without external position sensors.The drivers also have built-in positioning functions that enable relatively complex positioning operations. The motor shaft diameters are ⌀25 mm and rated thrust is 28 N to 118 N.
