Definitions
- the present invention relates to a suppressor system of a permanent magnet motor for activating a functional member of a motor vehicle.
- Such motors include power brushes associated with a collector and connected to an external power source by power wires.
- such engines also generally include a metal carcass.
- the subject of the invention is a suppressor system of a jnotor with permanent magnets for activating a functional member of a motor vehicle, in which the motor comprises power brushes connected to a source of external supply by wires and a metal carcass, characterized in that each brush is connected to the metal carcass of the motor through at least one suppressor capacitor, in that the metal carcass of the motor is connected to the ground of the vehicle, and in that the metal carcass of the engine and the functional member comprise complementary means of grounding the latter.
- This motor comprises for example a metal carcass designated by the general reference 2, in which are arranged for example permanent magnets designated by the general reference 3 and a rotating part designated by the general reference 4, provided with a shaft 5 on which are available 2 its for example a collector designated by the general reference 6 and other conventional type bodies, designated by the general reference 7.
- the collector 6 is associated with supply brushes, for example 8 and 9, which are connected by supply wires, for example 10 and 11, to a power source external to the motor, designated by the general reference 12 in this figure.
- each supply brush that is to say the brushes 8 and 9 is connected to the metal frame 2 of the motor through at least one suppressor capacitor, like the capacitors 13 and 14, and the metal carcass 2 of the engine is connected to the ground of the vehicle, for example at 15, in any suitable manner, as will be described in more detail below.
- These wires can also be associated with specific inductors such as the inductors designated by the general references 16 and 17 in this figure, or can be constituted by ferrite wires of conventional type, that is to say in which the core conductor of these wires is arranged in a ferrite sheath, itself surrounded by a layer of insulating material.
- Such a structure then makes it possible to adapt the characteristics of the LC circuits to the desired interference suppression characteristics.
- the metal carcass 2 of the engine can be, as described above, connected to the mass of the vehicle in any suitable manner.
- this carcass can be connected to the mass of the vehicle through a grounding braid or a piece of support for the functional member with which the engine is associated, etc.
- this grounding of the metal carcass of the engine can be ensured by a fastening part of this engine on the rest of the functional member.
- the activation motor is a motor for activating a seat with so-called motorized adjustments of a motor vehicle
- the metal carcass of the motor can be connected to the mass of the vehicle through the slide of the seat Or other. 3 It is therefore conceivable that such a structure then has a certain number of advantages, in particular in terms of its simplicity and therefore of its cost of production.
