ASR Series AC Servo Motor Driven Pump

ASR Series AC Servo Motor Driven Pump

Achieve space-saving and reduced wiring! The parameter settings use simple and reproducible digital adjustments.

We offer the "ASR Series AC Servo Motor Driven Pump," which allows for precise control of flow and pressure. The piston pump is directly driven by an AC servo motor, enabling control of the rotation speed from zero to the maximum speed, thus allowing for variable discharge volume. Additionally, the control deviation between the control signals from the upper level (speed and pressure commands) and the sensor signals is calculated by the AMSR controller, creating a feedback loop that drives the AC servo motor. 【Features】 ■ Control parameters can be digitally set using dedicated software ■ Energy-saving and low heat generation ■ Low noise ■ High performance ■ AMSR controller with digital settings that achieves space-saving and reduced wiring *For more details, please refer to the PDF materials or feel free to contact us.
