Abstract
A turning device for a turbomachine comprises a plurality of electromagnets connectable to an electric power source; a rotor magnetically coupled with the electromagnets, connectable to a main shaft of the turbomachine and having a rotation axis, the electromagnets are arranged facing the rotor in order to induce eddy currents on a surface of the rotor and apply a torque to the rotor, thus rotating the main shaft.
