摘要： A claw rotor (2) provided with an insulator (11) for a field coil (10) and a rotary electric machine equipped with such a rotor, the insulator comprising a plurality of projecting petals (121, 131) intended to engage with the inner inclined periphery of a claw (9). Each of the petals (121, 131) includes: a base (122, 132) solidly connected to an associated cheek (120, 130), side edges (123, 133), and an end (124, 134). The claw-pole rotor (2) is wherein each petal (121, 131) has a thickness (e) at the side edges (123, 133) which increases from the base (122, 132) to the end (124, 134).

摘要： A stator of a rotary electrical machine has a stator body formed by a stack of metal sheets. The stator body is delimited by inner and outer radial surfaces. Notches in the stator body extend axially. Each notch has a notch base and a notch opening, and the notch opening is on the side of the inner radial surface. A stator winding is supported by the stator body, and the winding has a plurality of winding parts. Each part is accommodated in one of the notches. Each of the notches at the notch opening has a closure element. Each winding par in a notch is retained between the notch base and the closure element. The closure elements are formed by offsetting at least one of the metal sheets of an adjacent notch in the direction of the notch.
