<p>The device has a linear stator (38) formed by magnetic elements rails (44A, 44B). The stator comprises succession of magnetic elements arranged parallel to the trajectory. Each element of the stator interacts magnetically with a magnetic element (36) proximal from a rotor (28) to drive a grip element (22) in rotation during displacement along a trajectory. The stator is arranged such that lines of magnetic field between the stator element and the element proximal from the rotor are directed parallel to a vertical rotation axis (A) of the rotor. The rails are arranged fixedly on a portion of a trajectory.</p> |
