CLAW-POLE ROTOR OF A ROTARY ELECTRICAL MACHINE PROVIDED WITH AT LEAST ONE CHAMFER MADE IN A TRAILING EDGE OF A CLAW

摘要

The invention relates in particular to a rotor of a rotary electrical machine of a motor vehicle, comprising: at least one polar wheel including a plurality of claws (29); each claw (29) comprising a leading edge (51) and a trailing edge (52) extending between a base (53) and a free end (54) of the corresponding claw (29); said rotor (12) being characterised in that at least one claw (29) comprises a chamfer (57) made in at least one trailing edge (52), and in that a ratio of a maximum width (chb_max) of said chamfer (57) to a pole pitch is between 0.16 and 0.37 in a range of operating speeds.
