Disclosed herein is a motor including a shaft, a rotor, a motor housing forming an inner space to receive the shaft and the rotor therein, a stator received in the motor housing and disposed outside the rotor based on a radial direction of the shaft, a first flow path disposed outside the stator based on the radial direction of the shaft such that a first fluid flows in the first flow path, the first fluid being discharged to the inner space and cooling the stator and the rotor, and a second flow path disposed between the first flow path and the stator based on the radial direction of the shaft such that a second fluid flows in the second flow path, the second fluid absorbing heat of the stator transferred through a flow path wall.
