Abstract

The invention relates to a rotor (2) for a permanent magnet synchronous machine, comprising a laminated core (6) arranged on a shaft (4) extending in the axial direction (A), a plurality of poles (14) being arranged around the periphery of the laminated core, wherein at least one magnet (10) is provided per pole. In order to ensure particularly good prevention against slipping of the magnets, pole gap rods (12) are positioned between the poles (14) in such a way that, in the peripheral direction, each magnet (10) is applied, by a first side (16a) and an opposing second side (16b), to a respective pole gap rod (12).
