The invention discloses a motor for a suspension system, the suspension system and a vehicle, and the motor for the suspension system comprises a housing which is internally provided with an accommodation cavity; a stator assembly, wherein the stator assembly is arranged in the accommodating cavity; the rotor assembly is arranged on the radial inner side of the stator assembly, the rotor assembly comprises a rotor shaft, a rotor iron core and a plurality of permanent magnets, the rotor iron core and the rotor shaft are coaxially fixed, the permanent magnets are arranged on the peripheral surface of the rotor iron core, and the permanent magnets are arranged on the outer circumferential surface of the rotor iron core. The plurality of permanent magnets are arranged along the axial direction of the rotor iron core, and at least parts of two adjacent permanent magnets in the axial direction of the rotor iron core are arranged in a staggered manner in the circumferential direction of the rotor iron core. According to the motor for the suspension system, the torque ripple output in the working process can be reduced, and the stability and the mute performance are improved.
