Abstract: The invention relates to a coil intended to be inserted in into a first and a second slot of a stator, the coil being wound in a plurality of successive turns, each turn comprising:—a first half-turn comprising a first slot portion configured to be inserted in into the first slot of the stator,—a second half-turn comprising a second slot portion configured to be inserted in into the second slot of the stator, the second half-turns each being connected to the first half-turn of the same turn and to the first half-turn of the next turn by junction portions on each side of the first and second slot portions, the junction portions of the coil stacking along at least two juxtaposed heads extending in mutually parallel junction planes.

Abstract: A stator (2) for a rotary electric machine (1), comprising:—a radially interior ring (25) comprising teeth (23) and slots (21) opening radially towards the outside and extending between the teeth, bridges of material (27) connecting two adjacent teeth to their base and defining the bottoms of the slots between these teeth,—coils (22) arranged in the slots, having electrical conductors arranged in an ordered fashion in the slots (21), and—a radially outer yoke (29) attached in contact with the ring, the yoke being formed of assembled sectors (30).

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.
