Abstract
A permanently excited synchronous machine includes a stator; a winding system arranged in grooves of a laminated core of the stator and forming winding overhangs on end faces of the laminated core, and a rotor connected in fixed rotative engagement to the shaft and having ferrite magnets which extend axially beyond the end faces of the laminated core. The rotor electromagnetically interacts with the stator across an air gap there between during operation of the permanently excited synchronous machine to cause a rotation about an axis of rotation. A flux concentration element is provided radially across each of the ferrite magnets of a magnetic pole and bundles magnetic field lines of the ferrite magnet onto an axial length of the laminated core of the stator. The flux concentration elements and held by a fixing element on the ferrite magnets of a magnetic pole.
