Patent ID: 8026640

Claim:
An electric machine, comprising: a first machine part including a stator element and a rotor element and constructed as a rotary actuator which interacts with a rotary movement of the rotor element; and a second machine part including a primary part and a secondary part and constructed as a linear actuator which interacts with a linear movement of the secondary part, wherein the rotor element of the first machine part and the secondary part of the second machine part are interconnected, wherein the secondary part of the second machine part is moveable in a rotating fashion and constructed as an external rotor, and wherein the secondary part of the second machine part has a central pin-type or tube-type element or an axial bore, for support of the secondary part in a radial direction in relation to the primary part, wherein the primary part of the second machine part includes a cavity, wherein the pin-like or tube-like element has an axial length sufficient to project into the cavity of the primary part, and wherein the pin-like or tube-like element is supported in the cavity of the primary part in relation to the primary part.
