Abstract According to the idea of aequilate curve double stator motor, the traditional CAM rotor blade motor was improved into double stator structure. Based on the traditional CAM rotor blade motor, the structure and the working principle of the double action CAM rotor blade motor with double stator were analyzed to calculate the theoretical displacement. The basic formula of theoretical displacement for the multi action CAM rotor blade motor was deduced. The instantaneous torque values of the hydraulic motor at different rotor turning points were analyzed, and the torque and the torque ripple coefficient in different compound mode of inside and outside motors were calculated. The results show that different compound mode of inside and outside motors can lead to many different kinds of torque. The minimum torque ripple can be obtained by combining two inside and one outside motor, while the maximum torque ripple can be obtained by combining two outside and one inside motor.
