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.

Abstract: An air pulse device according ding 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 a rotor (16) and a stator (14).

Abstract: A motor for moving a flap for distributing a flow of air in a duct of a heating, ventilation and/or air conditioning installation is supplied with voltage. A power-regulation module is mounted in series with the motor, and includes at least one positive-temperature-coefficient resistor, so that, when the flap reaches an open or closed position, the motor is blocked. This results in an increase in the current strength in the circuit, causing an increase in the value of the resistance, and this results in a reduction in the current strength and in the voltage at the terminals of the motor.
