The invention discloses a stator cooling system, a stator cooling method, a motor and a vehicle, and relates to the field of motors. The stator cooling system is applied to a motor of a vehicle and comprises a controller, a common rail pipe, an electric control nozzle, an oil pump and an oil rail pressure sensor, the oil pump is in transmission connection with a speed reducer of the vehicle, the input end of the oil pump is communicated with a lubricating oil way of the motor, and the output end of the oil pump is communicated with the common rail pipe; the electric control nozzle is arranged on the common rail pipe and used for spraying lubricating oil to a stator of the motor. The oil rail pressure sensor is used for detecting oil pressure in the common rail pipe; the controller is in communication connection with the oil rail pressure sensor and the electric control nozzle and used for controlling the electric control nozzle to be opened or closed according to the oil pressure. The stator cooling system provided by the invention is better in cooling effect and higher in safety.
