Abstract
A salient pole machine () comprises a rotor () rotating about a machine axis, said rotor () having at its circumference a rotor rim () with a predetermined outer radius (), whereby a plurality of salient poles (), each extending in radial direction, is attached to said rotor () at said rotor rim () at a respective pole-rim interface (). The mechanical properties of the configuration are improved by providing at said pole-rim interface () a plurality of axial rib-like rim extensions () projecting radially from said rotor rim () with a predetermined circumferential distance (d) between neighboring rim extensions (), by each salient pole () having a plurality of axial pole grooves () matching and receiving said rib-like rim extensions () at the respective pole-rim interface (), and by providing fixing elements () to fix said rib-like rim extensions () in said pole grooves ().
