Abstract
An air pulse device according to the invention is used, in particular, in a heating, ventilation and/or air conditioning system of a motor vehicle. The air pulse device comprises an electric motor (2) having a rotor (16) and a stator (14). The stator is mounted about a support means (10) such that it is in contact with said support means, the latter being made of an electrically conductive material and connected to an electrical ground. Moreover, a shield (70) is disposed in the vicinity of the stator, said shield also being electrically connected to the electrical ground.
