Features
1 High-speed positioning of large-inertia loads
Precision speed reducer combined with Megatorque Motor effectively attenuates reflected load
fluctuation and disturbance for high speed positioning.
Max. output torque of 1,960 N·m and applicable inertia up to 700 kg·m2. (Model SR6)
High-accuracy positioning performanceProvides +/- 5 arc-sec repeatability (precision type) using rigid-shaft design zero-backlash speed reducer

Product Configuration
Megatorque MotorTM
(PS series: High-speed outer rotor type)
This direct drive motor features high torque, high speed and compact
size.
It is capable of handling load inertia up to 100 times the rotor inertia.
The combination of proprietary disturbance observer and preview-
based feed-forward control configuration enables very-high-speed
positioning.
