A rotor for an electric machine is disclosed. The rotor has a rotor shaft, a laminated core arranged on the rotor shaft and a plurality of stacked electrical laminations. The rotor also includes a first end plate arranged on an axial side of the laminated core and having radial protrusions arranged along its circumference, a second end plate arranged on the opposite axial side of the laminated core and having radial protrusions arranged along its circumference, a plurality of rotor windings which are each wound around a protrusion of the first end plate and around an axially opposite protrusion of the second end plate. A central cooling duct runs in the rotor shaft for supplying a coolant, and a radial cooling duct runs outwards from the central cooling duct in the laminated core. In addition, an electric machine and a vehicle having an electric machine of this type are described.
