The invention relates to a thermal management system () for a motor vehicle, comprising:

Thermal management system for a motor vehicle and corresponding thermal management method

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 () having a rotor () and a stator (). The stator is mounted about a support means () 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 () is disposed in the vicinity of the stator, said shield also being electrically connected to the electrical ground.

Electronically switched electric motor and corresponding air pulse device

The invention relates to a module for controlling the power supply () of an electric motor which comprises a printed circuit board () bored with a plurality of through-holes (), respectively associated with an electrical connection pad () supported by said plate adjacent to each of said through-holes. The electrical connection pads () are arranged on a surface () of the printed circuit board () so that a virtual circle can be defined passing substantially through each of the connection pads, said pads being concentrated on a portion of the printed circuit board so as to form an arc of circle which is shorter than half the circumference of said virtual circle.
