The "Hybrid Actuator Technology Bulletin" features technical information on the next-generation hydraulic actuator "HySerpack" developed by Daiichi Electric. It introduces a wide range of implementation examples, including its adoption in the molten steel flow control device of the continuous casting equipment installed at Nippon Steel Corporation's Fukuyama Steel Works, as well as in rotary printing machines, seismic isolation rubber testing machines, and dam utilization discharge facilities. Additionally, it presents the specifications and usage examples of the ultra-high precision hybrid servo press "DPP-800," based on "HySerpack."

This document is a technical material regarding the next-generation hydraulic actuator developed by Daiichi Electric Co., Ltd. The "Hybrid Actuator" consists of three components: a servo motor, a bidirectional discharge hydraulic pump, and a hydraulic cylinder, and it requires no control valves at all, with piping and oil tanks kept to a minimum. Despite its extremely simple structure, it can control thrust and rod position with very high precision.

This document explains the new technology "Hydraulic Servo Control," which replaces the hydraulic servo valves developed by Daiichi Electric. Traditionally, the servo valves that have been used have had issues with poor energy efficiency and the difficulty of making adjustments after the equipment has been completed. The "Hydraulic Servo Control" developed by our company allows for the free control of hydraulic actuators by electronically controlling the servo motor without using a control valve. 【Contents】 ■ Issues with hydraulic servo valves ■ Division of roles between hydraulic servos and electric servos ■ New hydraulic servo control technology ■ Flow control of molten steel ■ Case studies - Steering devices for ships - Attitude control for aircraft - Intercept missiles - Energy-saving modifications for fatigue testing machines *For more details, please refer to the PDF document or feel free to contact us.
