Estun (China)

Estun Company is able to provide three series of all digital AC servo drives and five series of servo motors with a power range from 200w to 105kw which can be applied in a variety of industries such as: machine tools, packaging, textiles, semiconductors, plastic, printing etc.     Website


AC Servo System & Motion Control System
Wide range, various models: 0.2kW~22kW, current forward feedback control, auto tuning function, multiple feedback options, various communication protocols, ProNet-E series, universal servo, three phase 400V power supply models are available from 1kW to 22kW, low frequency vibration suppression function, with excellent performance at low speed movement, dynamic electronic gear ratio switching function.

AC Servo Drives
The response performance of the ProNet series servo drive has been greatly improved compared to the EDB series servo drive, through the addition of online real-time inspection of load inertia and gain adjustment to obtain optimal control. FFT Analysis to control the vibration.

Electro-hydraulic Servo Systems
Estun servo pump system realizes speed and pressure double closed loop control by AC servo drive and permanent magnet synchronic servo motor driving internal gear pump. The output flow rate is determined by servo motor speed and ration internal gear's output volume. The system pressure is real-time measured by another pressure sensor. Compared with constant rate pump or variable pump, it can obviously reduce the electric power charge, save cooling water and reduce the heat created by wasted power.
