Why HIWIN
Gearbox torque, direct drive.
To 3,600 newton meters
Water-cooled TMRW motors deliver machine-tool torque with no gearbox in the path: no backlash, no transmission losses.
A hollow shaft that works
Large through-bores route cables, coolant, and media straight down the axis of rotation.
Half the cogging
The TM-2 generation delivers larger torque while cutting cogging torque in half for smoother contouring.
Cooled for sustained duty
Water cooling holds the thermal budget through continuous machining cycles, not just peak bursts.
