This paper introduced an electro-hydraulic actuator based on direct driving servo motor and its application composition. And the advantages and disadvantages of direct driving electro-hydraulic actuators and traditional servo actuator were compared, respectively. Based on AMESim Simulation software, a servo motor direct drive electro-hydraulic actuator simulation model was established. Besides, a prototype of servo motor direct drive electro-hy draulic actuator was obtained and the related research and experiments were carried out. The results show that this electro-hydraulic actuator based on direct driving servo motor can meet the actual needs of the power plants and other applications.
