- the invention relates more particularly to a motor support for a fan wheel, in particular of a motor-fan unit.
- the invention also relates to a motor-fan unit for a heating, ventilation and/or air conditioning installation comprising such a motor support.
- a heating, ventilation and/or air conditioning installation which makes it possible to create an air flow in the passenger compartment.
- Such an installation also makes it possible to manage the temperature and distribution of the air flow created within the passenger compartment.
- a heating, ventilation and/or air conditioning installation comprises, among other things, a fan comprising a fan wheel driven in rotation by a particularly electric drive motor.

- An electronically commutated electric motor or brushless direct current motor (also known under the English name “brushless”), comprises a rotor and stator assembly, each of these components carrying electromagnetic elements whose interaction generates the movement of the rotor relative to the stator, and thus the movement of the fan wheel.
- the electric motor is assembled in the heating, ventilation and/or air conditioning installation via a motor support which comprises a base with an internal structure allowing the fixing of the electric motor, more precisely the stator.
- the motor and the control module include components which heat up during use; it is therefore necessary to ensure cooling of the motor and/or the control module.
