Miniature AC servomotor with high torque and high-resolution

Delivering a lineup with a wide range of application options of compact high-performance next-generation servo motors with built in encoders.

the servo motor has high acceleration and positioning,suitable in using as gearless.

The motor has characterristics of low speed and high torque (compared to general servo motors) because this motor is assumed that it will drive directry without using a gear(a deceleration mechanism).The integrated sensor realize high-precision positioning, and able to receive a direct load on the shaft by adopting high-load bearing as standard.

advantages:

• silent: since it has no vibraition sound.
• High precision: positioning by eliminating a machanical error  due to backlash.
• Weight and space saving　
• Improving acceleration
• feedback for master-slave control. 
• that can be generally obtained by using a gearless structure

The world's smallest servo motor of all hollow-shaft type.It is ideal for end effectors (hand, gripper, Zθ unit) and also small robot hands with a combination of low reduction ratio gears.
