A stator including a ring having teeth with slots there between, and bridges of material each connecting two adjacent teeth at their base on the side of the air gap and defining the bottom of the slot between these teeth. The bridges of material each having at least one region of reduced magnetic permeability that is in the form of at least one localized narrowing formed by a groove or a localized crushing of the material, and/or at least one opening with the width l of the bridge of material, and/or at least one localized treatment in the with l of the bridge of material, which locally reduces the magnetic permeability of the bridge of material, and windings placed in the slots of the ring.

Stator for a rotating electrical machine

A method for manufacturing a stator of an electrical machine. The method including: a toothed ring having teeth joined together by bridges of material and defining between them slots open radially toward the outside, windings produced outside of the slots, and a yoke configured to be attached to the toothed ring. The method also including attaching at least one piece of sheet-form insulation to at least a portion of each of the windings, inserting said winding portions with the insulation into the slots via a radial movement directed toward the inside of the slots, and assembling the yoke onto the radially exterior surface of the ring to close the slots radially.

A stator including a ring having teeth and slots between said teeth that open radially outwards and material bridges, each linking two adjacent teeth to the respective base on the side of the air-gap, a yoke attached to the ring, and windings placed in the slots of the ring, at least some of the material bridges having at least on deformable zone that can be deformed during assembly of the yoke on the ring.
