Motor Interface Design

Water cooling design
HIWIN torque motor can be cooled by water or air. (TM-2 and IM-2 are only available with water-cool) Water
cooling channel is designed on the outer case of stator. O-ring is installed outside the water cooling channels as
a leak-proof device. To ensure a good circulation of the coolant for cooling, the design coolant inlet and outlet
must be aligned with position on the approved drawing.
