Abstract
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.
