Precision Motorized Linear Stage EPSH Series (Servo)
Special machining process and anodized surface finish unify precision, wear resistance and appearance.; Ground-grade ball-screw transmission: high efficiency, low starting torque, free of chatter and backlash, high positioning and repeat positioning accuracy.; Precision-grade self-aligning ball linear guide with a light preload assembly process for high load capacity and good straightness and parallelism.; Panasonic servo motor with good torque-frequency characteristics, strong overload capacity, wide speed range and very low vibration and noise.; Two mechanical limit switches provide over-travel speed reduction and limit protection.; One photoelectric zero switch provides precise zero positioning and error correction, preventing error accumulation.; Standard DB9 interface for strong versatility and compatibility with the company’s motor controllers.; Standard mounting holes for easy installation and multi-axis module combinations.
Product Introduction
The EPSH series is an improved version of the EPSB series, adapted for smooth operation under low-speed, high-load conditions. It uses high-precision ground ball screws, precision-grade self-aligning ball linear guides and high-quality couplings, a Panasonic servo motor with good torque-frequency characteristics, strong overload capacity, a wide speed range and very low vibration/noise as the power source, and lightweight, high-strength aluminum alloy as the main body material. It offers high precision, strong load capacity, good stability, very low vibration and noise, and smooth operation without creeping at low speed under heavy load.
