High-rigidity and large-output-torque precision rotary positioning
unit using speed reducer and Megatorque MotorTM

3 Low profile, compact footprint and large through
holes

Minimized footprint includes motor with 222 mm low-profile height (Model SR6).
Output axis has 145 mm large through holes (Model SR6).

4 Max. 10 µm rotor run-out with high rigidity

High moment rigidity in low profile design achieved with custom bearings.
Moment load: Max. 9000 N·m, Rotor run-out: Max. 10 μm (Model SR6)

5 Custom Driver Unit with positioning
controller function

Positioning operation can be controlled without complicated communications or
additional controller.
Home position sensor incorporated so Megapositioner can be connected directly to
Driver Unit.

Zero-backlash precision speed reducer

Zero-backlash design is achieved by an input screw shape in which output
roller followers contact the output contact screw at consistent preload.
This design enables precise positioning in any rotating direction and maintains
accuracy without developing any wear.
