Times:2019-04-22Clicks:357

Main Features

KAH series hollow shaft rotary actuator provides large-torque and high-precision rotary actuation. With integrated design, processing and assembly technique, it is provided with high precision harmonic drive reducer, frame-less torque motor, hollow shaft high resolution absolute encoder, brake and intelligent sensor.

It provides high torque output and high torque density, for example, the torque of KAH-40 rotary actuator can reach 800N·m.

The positioning precision of rotary actuator is within 30 Arc sec.

An internal through-hole is set to facilitate threading of wires, gas pipe and laser beams, which simplify the system structure.

Dozens of product models are provided to meet diversified needs, and the products with 220 VAC, 110VAC and 48 VAC voltages are available.

High protection grade (IP67) makes the product applicable to severe working environment.

It can be used by matching with KDE series EtherCAT Bus Servo Drivers to realize ultra-low vibration control and reliable stable operation, through which offers an integrated drive control solution to customers.

 

Application Areas

KAH series rotary actuators have been widely used in many industrial fields, such as electronic and semiconductor equipment, precision machine tools, factory automation systems, precision laser processing devices, LED equipment, detection device, medical devices and instruments, industrial robots, printing machines, spraying machines, glass processing equipment, precision measuring instruments and so on.
