Speed control of a hydraulic motor using an on/off solenoid valve.

Hideki YANADA, Y. Yamamoto

Abstract

As microcomputers have become widespread and the response speed of on/off solenoid valves has been improved, digitally controlled hydraulic systems are used in many applications. This paper deals with speed control of a hydraulic motor using an on/off solenoid valve which is driven according to PWM control. Intermittent flow through the on/off solenoid valve causes large pressure fluctuations accompanied by speed fluctuations. In order to reduce these, the on/off solenoid valve and a hydraulic motor are connected by a high-pressure flexible hose. A compromise is made between the magnitude of pressure fluctuations and system response speed. The present work shows the usefulness of the speed control method in applications where simplicity of the hardware is desired and high response speed is not needed.
