Embodiment Construction

[0044] The air pulse device 1 making it possible to suck in and / or blow out air comprises at least one electronically switched motor 2 capable of rotationally driving a fan wheel 4 , here of the type with fins 6 , via a shaft 8 of the motor. The device also comprises at least one support means 10 combining several functions, including the support of the motor 2 , the cooling of the components of the device and the support of the control electronics board 12 of the motor.

[0045] The motor mainly includes an induction stator 14 and an induction rotor 16 , the induction rotor 16 supports the output shaft 8 capable of driving the fan impeller 4 . A stator 14 is fixed to the support means 10 of the electric machine, and a rotor 16 is arranged around the stator 14 to be driven in rotation under the action of a magnetic field generated by the windings and magnets associated with the rotor and stator.

[0046] Such as image 3As can be seen in , the stator 14 has an annular form wi...

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.

Description

technical field [0001] The invention relates to the field of motors, in particular to the field of electronic switch motors. More specifically, it relates to an air impulse device in a motor vehicle comprising such an electric machine. Background technique [0002] An air pulse device equipped with an electric machine according to the invention is used, for example, in a ventilation, heating and / or air conditioning system of a motor vehicle. [0003] An electronically switched motor, or brushless DC motor, includes a rotor and stator assembly, each of these components supporting electromagnetic elements that interact to produce motion of the rotor relative to the stator. The rotor and stator are mounted independently of each other in the motor, and it is important to ensure that the relative positioning of these two components is correct for optimal operation of the motor. In operation, these two components generate electromagnetic radiation, which may interfere with the o...
