ROTOR FOR A ROTATING ELECTRICAL MACHINE, EQUIPPED WITH A MAGNET CLAMPING ELEMENT

摘要

The invention relates primarily to a rotor (10) for a rotating electrical machine, in particular for an electric turbocharger, comprising: a rotor body (11) defining a plurality of cavities (21); and a set of permanent magnets (22), in particular having radial magnetisation, housed in the cavities (21). The rotor is characterised in that: at least one clamping element (51) is disposed between the rotor body (11) and a corresponding permanent magnet (22), in order to maintain the permanent magnet (22) in place, said clamping element (51) being arranged such that it is located in the passage of the magnetic flux generated by the corresponding permanent magnet (22).
