Linear motor, suspension system and vehicle

The utility model provides a linear motor, a suspension system and a vehicle. The linear motor comprises a first component, a second component and a heat exchange cavity. The first component is provided with a containing cavity used for containing a heat exchange medium. The second component can reciprocate in the containing cavity in the first direction. The heat exchange cavity is provided with a first communication opening and a second communication opening which communicate with the containing cavity. The first component comprises one of magnetic steel and a winding, and the second component comprises the other one of the magnetic steel and the winding; the first communicating opening and the second communicating opening are spaced in the first direction, so that in the moving process of the second component, the heat exchange medium can flow between the containing cavity and the heat exchange cavity. According to the linear motor provided by the utility model, through the design of the heat exchange cham
