An x-ray source device includes an anode for generating x-rays via an electron beam striking a focal point of the anode, the anode being rotatable about an axis of rotation via an electric motor including a stator and a rotor, the stator including a first coil end, relatively nearer to the anode and a second coil end, relatively further from the anode. A laminated core of the stator is arranged between the first and second coil ends. The first coil end includes a first intersection area, relatively further from the focal point and a second intersection area, relatively nearer to the focal point, with respect to the focal plane. A maximal external radius of the second intersection area is relatively smaller than a maximal external radius of the laminated core in the focal plane.
