an electromechanical converter endowed with a rotating portion defining an axial direction and a radial direction, an electronic control unit, an electrical filtering means, and a housing comprising a cooling device including fins, wherein:

the electromechanical converter, the electronic control unit, and the filtering means are accommodated inside the housing such that the fins surround the electromechanical converter, the electronic control unit, and the filtering means;

the electronic control unit comprises an electrical converter configured to power the electromechanical converter;

the housing is cylindrical; and

the electrical converter comprises one or more electronic boards disposed inside the housing; and

wherein the smart motor further comprises an impeller connected directly to the electromechanical converter via a mechanical transmission shaft, the electromechanical converter being positioned in the axial direction between the impeller and the electronic control unit, blades of the impeller surrounded by the housing, ends of the blade of the impeller overlapping the fins in the radial direction, and the blades of the impeller being in fluid communication with the fins so that the fins are crossed by a flow of air delivered by the blades of the impeller, thereby cooling the electromechanical converter, the electronic control unit, and the filtering means surrounded by the fins.
