Claw rotor provided with an excitation winding insulator, and rotary electrical machine equipped with the claw rotor

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).
