Problems solved by technology

However, this makes the winding operation difficult, mainly due to the size of the stator notches, and there are few options for the supply of this wire from a limited number of suppliers
In addition, the magnetic noise generated by the machine is relatively high

Embodiment Construction

[0045] Identical, similar or equivalent elements are provided with the same reference symbols in the various figures. Throughout the following description, the side of the stator referred to as "front" is located on one side of the interconnector and the side referred to as "rear" is located on the opposite axial side.

[0046] figure 1 An example of a rotating electric machine 10 is shown. In this example, it involves a brushless direct current (BLDC) rotary motor.

[0047] The rotating electric machine 10 includes a bell-shaped rotor 11 to which a blower (not shown) is fixed. The rotor 11 supports on its inner circumference a plurality of permanent magnets 12 forming the magnetic poles of the machine 10 . The rotor 11 is rotatably mounted on a shaft 13 from a radiator 16 containing the electronic modules for controlling the machine 10 .

[0048] The rotor 11 surrounds a multi-phase stator 17 with a gap between the inner circumference of the rotor 11 and the outer circumf...

Abstract

The invention generally relates to a rotating electrical machine, in particular for use in motor vehicles, comprising: - a stator (17) comprising a main body (21) and polyphase windings (22); ) with a gap between the outer circumference of the rotor and the inner circumference of the rotor; - the rotor comprises a plurality of magnetic poles; - the winding (22) is formed by a plurality of coils (36), each coil (36) being wound on a corresponding tooth of the stator body (21) (23), characterized in that the winding (22) is formed by 18 coils (36), and the rotor includes 12 magnetic poles.

Description

technical field [0001] The invention relates to a rotating electrical machine equipped with windings having an improved configuration. Background technique [0002] The invention has a particularly advantageous but not exclusive application in the field of electric machines operating in motor mode in order to rotate fans of motor vehicles. [0003] Mounted at the front of the vehicle, this fan is designed to create airflow across stacked heat exchangers, such as an engine cooler and air conditioning condenser located one behind the other. [0004] To this end, these fans consist of a blower set in rotation by a bell-shaped rotor positioned around an externally toothed stator. In practice, the stator consists of a body provided with a plurality of teeth distributed evenly and angularly over the periphery of the cylinder head. [0005] The multiphase winding inserted into the stator recesses is obtained, for example, from individual coils, each coil being wound on a tooth of...
