摘要：
An electrical machine (1) comprising: a rotatable drive shaft having a rotational axis (15); a rotor assembly (2) connected to the drive shaft, the rotor assembly 2 arranged to generate a static rotor magnetic field; a primary stator assembly (4), comprising a plurality of stator coils (5a, 5b) arranged to generate a rotating stator magnetic field for interacting with the static rotor magnetic field of the rotor assembly (2) such as to rotate the rotor assembly (2) along the rotational axis (15), and a secondary stator assembly (7) arranged to generate a static stator magnetic field; wherein the electrical machine (1) comprises a magnetic torsion spring (9) formed by the interaction of the static stator magnetic field with the static rotor magnetic field.
