Rotor with tubular cooling channels for electric machine

The invention relates to a rotor (1) for an electric machine, comprising: a rotor shaft (3); a laminated core (2) which is arranged on the rotor shaft (3), is formed by stacked electrical laminations, and has a laminated core projection (4) which projects radially outward; a first end plate (5), which is arranged on a first axial side of the laminated core (2) and has a radially outwardly projecting end plate projection (7); a second end plate (6) which is arranged on an opposite second axial side of the laminated core (2) and which has a radially outwardly projecting end plate projection (8); a plurality of rotor windings (9) each wound around an end plate projection (7) of the first end plate (5), an axially opposite end plate projection (8) of the second end plate (6), and a laminated core projection (4) extending axially between the two end plate projections (7, 8); a cup-shaped first end cap (10) axially covering the first end plate (5); a cup-shaped second end cap (11) axially covering the second end pl
