A ROTOR OF AN ELECTRIC ROTATING MACHINE AND AN ELECTRIC ROTATING MACHINE COMPRISING SUCH A ROTOR

A rotor of an electric motor includes several poles arranged circumferentially relative to the rotor, each pole having a first set proximate a rotor outer edge and a second set farther from the latter. The first and second sets are symmetrical relative to a d-axis. Each symmetrical part in the second set has two opposite ends terminating respectively with an outer flux barrier proximate the outer edge and an opposite inner flux barrier, both inner flux barriers being separated from each other by an arrangement having two radially-extending inner bridges flanking a central radially-extending flux barrier aligned along the d-axis.
