Design of High Speed Solenoid Actuator for Hydraulic Servo Valve Operation

Abstract

Modern electric controlled valves are demanded that its solenoid actuator should be smaller size, lighter weight, lower consumption power, and higher response time. For achieving these purposes, the major design factors of solenoid actuator such as magnetic flux density, coil turn numbers, plunger size, bobbin dimension, and etc. are must be optimized. In this study, for optimal design of high speed solenoid actuator for hydraulic servo valve operation, we draw up governing equations which are composed by combination of electromagnetic theories and empirical knowledge, and deduct the values of major design factors by use of them. For more increase the operating speed, voice coil are used as main armature in manufacturing of prototype actuator. And, we have proven the propriety of the governing equations and speed increasing method by experiments using the hydraulic valve assembly adopted the prototype of solenoid actuator.

Simulation and Modelling of Solenoid in Switch Gear

“…He focused on the design of the valve body and did not address the process of the coil design, which is a core part of the design of a solenoid valve. Sung [4,5] have developed a design program for ON/OFF type solenoid actuators. Their design summarized 22 input parameters and 18 design parameters based on electromagnetic theories, experimental values, and their experiences.…”

A Study on the Manufacture of Permanent Magnet Traction Control Valve for Electronic Stability Control in Electric Vehicles

“…The on/off solenoid valve that opens and closes the flow path or the proportional control solenoid valve that controls the flow rate by current has been mainly studied. Sung derived the governing equations for optimal on/off solenoid design and developed a design program consisting of electromagnetic theory and experimental parameter values [17]. Wu et al studied the modeling, optimization, and validation methods of a hollow plunger-type solenoid for a high-speed on/off valve [18].…”

High-pressure electrorheological valve with full pQ-functionality for servohydraulic applications

“…Therefore, electromechanical transducers were optimized. They are utilized for both direct and pilot stage drives (Bauer and Reichert, 2005; Reichert and Murrenhoff, 2006; Sangiah et al, 2013; Sung and Kim, 2013). Both cases demand large strokes at high operating frequencies of the drive in order to reach high flow rate at high switching speeds.…”
