Hydraulic valves were designed with two dimensional (2D) concept uniquely integrated pilot stage and power stage into single spool by taking advantage of both translational and rotary degrees of freedom. It was featured with simple structure, excellent anti-pollution capability, high ratio of power to weight and fast dynamic response, which attracted considerable attention in several areas of modern industry. In order to solve the problem that hydraulic servo screw of direct position feedback 2D servo valve had deficiency of complicated structure and high manufacturing cost，a novel paddle wing torque motor with feedback function was proposed. The motor could be used as electromechanical converter and directly connected with spool to constitute a novel force feedback 2D servo valve with simple structure and low manufacturing cost, which was suitable for civil servo valve application. Three types of prototype motors with different inclined angles of paddle wing were manufactured and the test rig was built. The relationships between feedback torque and armature displacement were studied by using methods of magnetic circuit analysis, FEM simulation and experiments. The experimental results were agreed with the simulated results. It was indicated the characteristics between feedback torque and armature displacement were close to linear relationship and its amplitude was raised with the increase of displacement, whose magnitudes reached about 0.098N·m, 0.132N·m and 0.16N·m with paddle wing’s inclined angles of 9°, 12°and 15°, respectively. It was proved that increasing inclined angle was an effective approach to increase feedback torque.
