ASE Series Yuken AC Servo Motor Driven Pumps
1. Product Overview
The YUKEN ASE Series is an innovative electro-hydraulic integrated servo pump system that directly drives a piston pump with an AC servo motor, combining the advantages of both electric and hydraulic systems. It is primarily designed as a high-efficiency hydraulic power source for industrial machinery, particularly excelling in injection molding applications.
2. Core Features
1. Excellent Energy-Saving Effect
-
On-demand oil supply: Adjusts flow and pressure in real-time according to system requirements, eliminating overflow losses
-
Energy savings of 30-70%: Compared to traditional fixed displacement pump systems with throttling control
-
Reduced heat generation: Lower energy consumption minimizes hydraulic oil temperature rise, extending oil life and reducing cooling system load
2. Compact Integrated Design
-
All-in-one unit: Integrated motor and piston pump assembly saves up to 70% installation space
-
Simplified piping: Reduced hydraulic connections improve system reliability and reduce leakage risks
-
Lightweight construction: Easier handling and installation compared to separate motor-pump configurations
3. Precision Control Performance
-
Precise speed/torque control: Utilizes YUKEN’s proprietary analog electronic encoder algorithm without requiring additional encoders
-
Fast response time: Servo motor control enables rapid acceleration/deceleration and pressure changes
-
Stable pressure holding: Maintains consistent pressure during molding cycles, improving product quality consistency
4. Low Noise and Environmental Protection
-
Noise reduction of 10-15dB: Quieter operation than conventional hydraulic systems
-
EMC filter: Environmentally friendly design reduces electrical noise interference
-
Lower carbon footprint: Energy efficiency contributes to reduced greenhouse gas emissions
