Embodiment Construction

[0031] figure 1 is a schematic sectional view with a blower device 100 equipped with an electric motor 101 according to the invention. The electric motor 101 comprises a stator 2 and a rotor 3 , a motor support 5 , an electronic body 7 adapted to control said motor, a heat sink 8 , elements 9 for supporting said rotor 3 and said stator 2 . The electric motor 101 comprises at least one channel 10 for circulating a fluid flow, for example an air flow, for cooling said motor 101 . Thus, in the illustrated embodiment, the electric motor 101 has an air flow therethrough.

[0032] It will be noted, however, that the fluid cooling the electric motor 101 can be a gas, a liquid, or a two-phase gas-liquid mixture. The fluid is, for example, water, refrigerant fluid (such as R134A, HFO 1234YF, carbon dioxide, etc.), and the like.

[0033] The blower device 100 comprises at least one electric motor 101 and at least one fan 4 cooperating with said at least one electric motor 101 .

Abstract

The invention relates to an electric motor (100) comprising a stator (2) and a rotor (3), the rotor (3) being arranged around the stator (2), an element (9) for supporting said rotor (3) and said stator (2), a motor support (5) through which a stream of fluid flows, a radiator (8) and an electronic body (7), said radiator (8) being inserted between said motor (100) support (5) and said electronic body (7), characterised in that the element (9) for supporting the rotor (3) and the stator (2), and the radiator (8), form the same so-called bifunctional part (30).

Description

technical field [0001] The invention relates to the field of electric motors. More particularly, but not exclusively, the present invention relates to electric motors for use in blower devices. A blower device equipped with an electric motor according to the invention is used, for example, in a ventilation, heating and / or air-conditioning system of a motor vehicle. Background technique [0002] Electric motors are generally based on the interaction of a rotor and a stator, which are mounted independently of each other in the motor. As a result of this, this motor has the disadvantage of not ensuring a good coaxial relationship between the rotor and the stator. Now, a poor coaxial relationship between these two elements can lead to a risk of motor failure, eg alternation of acceleration and deceleration phases. Contents of the invention [0003] Thus, the electric motor according to the invention makes it possible to ensure a uniform and regular operation of the electric...
