The invention discloses a steam motor. The steam motor aims at solving the defect caused by the fact that the existing exhaust gas can not be recycled. The steam motor comprises a valve mechanism, a power output mechanism and an air cylinder body. The air cylinder body is in a sealing arranged cylinder body shape. A piston is installed in the air cylinder body. The piston can move in a reciprocating mode along a lengthways direction of the air cylinder body under the driving of the piston. The valve mechanism is provided with a valve shaft. An air inlet groove and an air outlet groove are formed in the valve shaft, wherein the air inlet groove and the air outlet groove are communicated with the air cylinder body. The external exhaust gas can be entered into or discharged the air cylinder body through the air inlet groove and the air outlet groove. The power output mechanism is in fit connection with the valve mechanism. The power output mechanism is provided with a bent shaft. One end of the bent shaft is in fit connection with the piston and the other end of the bent shaft is connected with an engine through a driving assembly. The discharged exhaust gas in an air exhaust pipe of the engine steam motor can heat water into steams and the steams are fed into the air cylinder body. Then, formative energy is delivered to the engine through the driving assembly so that energy conversion and recycling of exhaust gas waste heat are achieved.
