An electric vehicle driving source of an RV reducer type hub motor comprises a permanent magnet synchronous servo motor, the fixed end of the permanent magnet synchronous servo motor is connected with a suspension connecting piece, the power output end of the permanent magnet synchronous servo motor is connected with the power input end of an RV reducer, and the power output end of the RV reducer is connected with a tire module; the power output of the permanent magnet synchronous servo motor and the power input and output of the RV speed reducer are the same main shaft; the wheel is compositely driven by the high-speed permanent-magnet synchronous servo motor and the large-transmission-ratio RV speed reducer, the power performance of the whole vehicle can be greatly improved, the structure is simple, the size is small, the weight is light, the larger transmission ratio can be provided under the smaller size due to the application of the RV speed reducer, and the service life of the vehicle is prolonged. The high-speed permanent magnet synchronous servo motor is adopted, so that the motor has the advantages of good starting capability, strong low-speed dragging capability, high power density and the like.
