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.

An electromagnetic pole () for a rotary electric machine is disclosed. The pole has a tooth () comprising a tooth body (), the tooth () being radially oriented and the tooth () comprising a recess (), a coil () comprising a plurality of wire turns () wound around the tooth () between a first radial end () and a second radial end (), the wire turns () which are the most distant from the tooth body () between the first radial end () and the second radial end (), forming an outer wire layer (), the coil () comprising a bracing wire (), the bracing wire () being wound on the outer wire layer () from the first radial end () to the second radial end () in less than one turn around the tooth () so as to hold in position the outer wire layer ().
