## Abstract

The subject of the invention is a motor support for a blower of a motor vehicle heating, ventilation and/or air-conditioning system, comprising a first ring (3), referred to as an outer ring, and a second ring (4), referred to as an inner ring, positioned inside the outer ring, the inner ring being configured to house an electric motor, and the outer ring being configured to be fixed to part of the motor vehicle heating, ventilation and/or air-conditioning system, said inner ring comprising an axial retention device (12) for the retention of said motor and at least one end stop (13) able to collaborate with an associated bearing surface (14) of the outer ring (3).

## Claims

### Claim 1

A motor support for an air blower of a motor vehicle heating, ventilating and/or air conditioning system, comprising:
a first outer ring; and
a second inner ring placed inside said first ring,
the inner ring being configured to house an electric motor, and the outer ring being configured to be fixed to a part of the heating, ventilating and/or air conditioning system of the motor vehicle, said inner ring comprising an axial retention device for said motor and at least one stop that can engage an associated bearing area of the outer ring.

### Claim 2 (depends on 1)

The motor support as claimed in claim 1, wherein the inner ring comprises a plurality of stops, and the outer ring comprises a plurality of bearing areas, each of said stops being able to engage at least one of said bearing areas.

### Claim 3 (depends on 1)

The motor support as claimed in claim 1, wherein at least one stop of the inner ring comprises a wall facing the bearing area of the outer ring and spaced from the bearing area by a distance of between 1 mm and 5 mm.

### Claim 4 (depends on 1)

The motor support as claimed in claim 1, wherein the inner ring comprises stiffening ribs.

### Claim 5 (depends on 1)

The motor support as claimed in claim 1, wherein the inner ring comprises two diametrically opposite motor balancing windows.

### Claim 6 (depends on 1)

The motor support as claimed in claim 1, wherein the axial retention device comprises a plurality of axial retention components, each axial retention component projecting axially out from a main body of the inner ring from a base as far as a head, at least one of the stops comprising an end at least partially facing said base of one of the axial retention components.

### Claim 7 (depends on 1)

The motor support as claimed in claim 1, comprising at least one vibration decoupling block placed between the inner ring and the outer ring.

### Claim 8 (depends on 7)

The motor support as claimed in claim 7, wherein the outer ring comprises at least one damping finger having an at least partially spherical end that can engage said at least one vibration decoupling block.

### Claim 9 (depends on 1)

The motor support as claimed in claim 1, wherein the inner and outer rings are coaxial.

### Claim 10

An air blower for a motor vehicle heating, ventilating and/or air conditioning system, comprising:
a motor support having a first outer ring and a second inner ring placed inside said first ring,
the inner ring being configured to house an electric motor, and the outer ring being configured to be fixed to a part of the heating, ventilating and/or air conditioning system of the motor vehicle, said inner ring comprising an axial retention device for said motor and at least one stop that can engage an associated bearing area of the outer ring
an electric motor housed in the inner ring; and
a protective cover for the motor and for the motor support.
