NAS Eseries

Tipical application
Product overview

The series uses resolver feedback, to achieve torque control, speed control and the implement closed-loop position control on motor shaft, also support optical encoder feedback, grating ruler feedback etc., to allow the target object has whole closed-loop control .          

Advantage          

1. Precision control (speed accuracy 0.1%, torque fluctuation less than 1%);          

2. Better energy saving (10-15% more than ordinary servo );          

3. Explosive power (15ms no-load acceleration, 26ms full load acceleration).
