The utility model relates to an inner curve radial plunger motor, which comprises a shell, a piston rod and a piston rod, the front end of the output shaft extends out of the inner cavity, and the rear end of the output shaft is located in the inner cavity; the cylinder body is located in the inner cavity and connected with the output shaft, and a plunger hole extending outwards in the radial direction of the cylinder body is formed in the cylinder body; the plunger is located in the plunger hole and directly or indirectly abuts against the curved-surface guide rail so as to move in the radial direction under the guidance of the curved-surface guide rail; wherein the outer surface of the plunger and the inner surface of the plunger hole are contact surfaces subjected to finish machining, and the roughness of the inner surface of the plunger hole is smaller than that of the outer surface of the plunger. According to the inner curve radial plunger motor, the contact surface with high precision is arranged to be
