The invention provides a motor, an electric power steering system and a vehicle. The motor comprises a shell, the inner surface of the shell is provided with a first wall surface and a second wall surface, and the first wall surface is located on one side of the second wall surface in the axial direction of the motor; the stator is arranged in the shell, the stator comprises a busbar arranged in the shell, the busbar comprises a base and a plurality of bus bars, the bus bars are arranged on the base, each bus bar comprises a connecting part, the base is closer to the second wall surface relative to the first wall surface, and a gap is formed between the base and the second wall surface; the winding is provided with a winding coil and a winding outgoing line, and the winding outgoing line is connected with the connecting part; and the distance H1 from the connecting part to the second wall surface, the distance H2 from the end part of the winding outgoing line to the second wall surface and the distance H3 from the base to the second wall surface meet the condition that H2 is greater than H3 and less than H1. The internal structure of the motor is more compact on the premise of ensuring the electrical safety distance of the motor.
