NEW MAGNETIC ARCHITECTURE FOR REDUCING LOSSES ON A HIGH-SPEED ELECTRIC MACHINE

Abstract

The invention relates to an electric machine (100) for a vehicle comprising a stator (10), coaxial with a rotor (20), comprising a stack of stator laminations made of stator material with alternating slots (11) and teeth (12), and a winding made of winding material formed in windings around the teeth (12) in the slots (11), the electric machine (100) comprising a power unit supplying these windings with alternating current and creating a variable stator magnetic field, interacting with the rotor (20) to drive it into rotation, this electric machine (100) comprising means for reducing losses by alternating current at high rotational speed, arranged to reduce the field lines passing through the winding material in the windings, in the form of inserts made of a material more magnetically permeable than the winding material and the stator material,The invention also relates to a motor vehicle comprising at least one such electric machine (100).
