External Rotor
FOI112 series

DDR motors are torque motors that directly drive the load without any transmission components. DDR motors have a compact structure and high rigidity. 

Strong. They generate high torque by using high-energy permanent magnets. At the same time, they are equipped with built-in optical encoders, which make the system have better positioning accuracy. 

Higher bit precision and a more dynamic response. The use of high-rigidity crossed roller bearings enhances the mechanical characteristics of the system.
