The invention relates to an electric machine which comprises a first machine part (30), comprising a stator element (31) and a rotor element (32) and being configured as a rotary actuator which interacts with a rotary movement of the rotor element (32). The electric machine (40) also comprises a second machine part (20), comprising a primary part (1) and a secondary part (2) and being configured as a linear actuator which interacts with a linear movement of the secondary part (2). The rotor element (32) of the first machine part (30) and the secondary part (2) of the second machine part (20) are interlinked. The secondary part (2) of the second machine part (20) can be rotated and is configured as an external rotor. Such a secondary part (2) allows to generate a higher power of a secondary machine part (20) acting as the linear motor. The secondary part (2) is mounted in the center thereof in relation to the primary part (1).
