Example Embodiment

[0115]Figure 1 to Figure 6The stator 2 of the rotating electric machine 1 is shown, and the rotating electric machine 1 further has a rotor not shown. In the case of a synchronous motor, the stator can generate a rotating magnetic field that drives the rotor to rotate, while in the case of an alternator, the rotation of the rotor causes an electromotive force in the electrical conductors of the stator.

[0116]The examples illustrated below are schematic and do not necessarily consider the relative sizes of the respective constituent elements.

[0117]The stator 2 has an electric conductor 22 arranged in a slot 21 formed between the teeth 23 of the stator mass portion 25. The notches 21 are closed, that is, a complete circuit can be formed around each slot 21 without encountering a cut in the stator mass. The slot 21 is closed on the air gap side by a material bridge 27 and on the opposite side by a yoke 29, each material bridge 27 connecting two consecutive teeth of the stator mass 25. T...

Abstract

The invention relates to a stator of a rotating electrical machine, comprising a stator mass that has slots in which electrical conductors are housed, inserted axially into said slots, wherein each ofthe slots has an uninterruptedly closed contour.

Description

technical field [0001] The present invention relates to rotating electric machines and, more particularly, to stators of such machines. Background technique [0002] In known stators, the yoke is formed with slots which are completely or partially open in the direction of the air gap in order to allow the introduction of the windings. Typically, half-open slots receive electrical conductors of circular cross-section arranged loosely, while fully open slots receive electrical conductors of rectangular cross-section arranged in an orderly manner. [0003] The known stators can close the slots with non-magnetic wedges. However, such wedges risk disengagement and hinder the operation of the machine. [0004] Patent application FR 3 019 947 describes a stator with a toothed ring having teeth connected to each other by bridges of material and defining between each other slots for receiving coils, the slots are oriented towards The outside is radially open. The opening of the s...
