ROTOR OF A ROTARY ELECTRIC MACHINE WITH OPTIMISED PLACEMENT OF ATTACHMENT MEANS

摘要

The invention relates mainly to a rotor (10) of a rotary electric machine having an axis of rotation (X) and including: a rotor body (11) made up of a packet of sheets, a set of permanent magnets (22), and a plurality of holes (13) made in said rotor body (11) in order to each allow the passage of a means (14) for attaching the sheets of said rotor body (11), characterised in that a ratio between a radial distance separating an axis of each attachment hole (13) relative to said rotation axis (X) and an external radius of said rotor body (11) is lower than 70%, in particular lower than 65%.
