Abstract
Methods and systems are provided for an electric machine. In example, an electric machine includes a stator that electromagnetically interacts with a rotor during electric machine operation. The electric machine further includes a first gear coupled to or included in a rotor shaft, a spring assembly coupled to a first side of the rotor and exerting a first axial force on the rotor, and a second gear that meshes with the first gear and exerts a second axial force that is opposite the first axial force, where a magnitude of the second axial force corresponds to a rotor torque.
