Patent ID: 8720297

Claim:
A parallel robot, comprising: a body, at least a portion of the body arranged as a stator of a circular motor; two articulated elements, each element including an arm and a forearm connected by a joint, the articulated elements rotatable about a single geometrical axis; an endpiece, an outer end of each forearm connected to the endpiece in articulated manner; and two annular segments forming two movable parts of the circular motor, the two movable parts assigned to a common circular path of the stator, each articulated element attached to a respective annular segment; wherein the circular motor includes permanent magnets forming the circular path of the stator, each of the two movable parts including a plurality of coils and a ferromagnetic piece arranged to close a magnetic flux of the permanent magnets and to generate a magnetic attractive force between the movable part and the circular path to prestress the annular segment that forms the movable part by the magnetic attractive force.
