To improve the performance of the dual stator cam rotor blade motor, the influence of blade friction coefficient on the torque performance of the dual stator cam rotor blade motor was studied. A mechanical model of the torque of the dual stator cam rotor blade motor was established under four different working modes: external motor working alone, internal motor working alone, internal and external motor working together, and internal and external motor differential working. By analyzing the forces acting on the outer and inner motor blades on different curve segments, the relationship between the friction coefficient between the blades and blade grooves and the positive pressure of the cam rotor on the outer and inner motor blades was derived. The expression for the relationship between the blade and the resistance torque of the cam rotor was obtained, and finally, the mechanical model was simulated and calculated. The results indicate that an increase in friction coefficient will reduce the positive pressure between the blades and the cam rotor, thereby increasing the resistance torque of the blades to the cam rotor. Reducing the surface roughness and geometric tolerances between the blades and blade slots can improve the performance of dual stator cam rotor blade motors to a certain extent.
