A rotor for a permanent magnet synchronous machine includes a laminated core having recesses in which respective permanent magnets are received. Each recess has a first end region which is closer to an axis of rotation of the rotor than a second end region. The permanent magnets are arranged in recesses which are adjacent to one another and of which the first end regions are closer to one another in the circumferential direction of the rotor than the second end regions. This arrangement is such that similar poles of the permanent magnets face one another. The rotor has a holding part by way of which a first portion of the laminated core is coupled to a second portion of the laminated core. The holding part has a lower magnetic conductivity than a subregion of the laminated core, the volume of which is equal to a volume of the holding part.
