Nippon Pulse
has provided a wide array of motion control solutions, including industry leading stepper motors, the innovative Linear Shaft Motor, controllers, drivers and networks.
A wide range of product offerings and expertise in application engineering makes NPM a discerning partner in motion control technology and implementation
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:
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.
