Abstract

The invention relates to a rotor (3) for a switched reluctance machine (1), comprising a rotary structure (9) provided with a plurality of ferromagnetic teeth (11) and intended to co-operate with a stator (5) disposed around the rotor (3). The invention is characterised in that a regularly arranged ferromagnetic bridge (17) is provided for each pair of teeth (11) of the rotor structure, which bridge is connected to the end edge (19) of a first tooth (11) and to the facing (21) side (11a) of a second tooth (11) adjacent to the first.
