Abstract (en)
[origin: WO2007140504A1] Electromagnetic rotary drive device (10) having a stator which has electromagnet devices which interact with a rotor (11), which is formed with at least one permanent magnet (13), in order to rotate it, and likewise to provide an electromagnetic bearing for it, and having an open-loop and/or closed-loop control device (20) for the electromagnetic bearing and rotation of the rotor (11), with the stator being in the form of segments (14) with an extender (19) over only a portion of the geometric circle circumference defined by the rotor (11), with force components (3a, 3b) being formed during operation in the direction tangential to the surface of the rotor (11) and in the normal direction by the currents supplied to the electromagnet devices (15, 21) of the segments (14) of the stator, which force components (3a, 3b) cause a torque as well as two supporting forces in different radial directions at right angles to the rotor rotation axis (7).
